Metals, Metalloids, and Nonmetals
Properties of Metals. Most of the elements are metals. Metals include the alkali metal, alkaline earth, transition metal, basic metal, lanthanide, and actinide groups. These elements have metallic character, which means atoms easily lose electrons. Metals display the following properties: Solid at room temperature (with the exception of mercury)
Alkali metal
The alkali metals all react violently with water according to M + H 2 O → MOH + 1/2 H 2. The rate of the reaction depends on the degree of metal surface presented to the liquid. With small metal droplets or thin films of alkali metal, the reaction can be explosive. The rate of the reaction of water with the alkali metals increases with ...
4.6: The Periodic Table of the Elements
Some of the groups have widely-used common names, including the alkali metals (Group 1) and the alkaline earth metals (Group 2) on the far left, and the halogens (Group 17) and the noble gases (Group 18) on the far right. The elements can be broadly divided into metals, nonmetals, and semimetals. Semimetals exhibit properties …
List of Metals
Nearly 75% of all the elements in the Periodic Table are classified as metals. Examples of metals are gold, aluminium, copper, iron, lead, silver, platinum, uranium and zinc. In the Periodic Table metals are separated into the groups detailed in the following list: Alkali Metals. Alkaline Earth Metals.
21.3: Group 2: The Alkaline Earth Metals
The alkaline earth metals are produced for industrial use by electrolytic reduction of their molten chlorides, as indicated in this equation for calcium: CaCl2 (l) → Ca(l) + Cl2 (g) (21.3.2) (21.3.2) C a C l 2 ( l) → C a ( l) + C l 2 ( g) The group 2 metal chlorides are obtained from a variety of sources.

Group 2 Elements: The Alkaline Earth Metals
Calcium is the 20th element in the periodic table. It is a group 2 metal, also known as an alkaline-earth metal, and no populated d-orbital electrons. Calcium is the fifth most abundant element by mass (3.4%) in both the Earth''s crust and in seawater. All living organisms (in fact, even dead ones) have and need calcium for survival.
Alkaline Earth Metals
The alkaline earth metals are the elements that correspond to group 2 of the modern periodic table. This group of elements includes beryllium, magnesium, calcium, strontium, barium, and radium.The elements of this group are quite similar in their physical and chemical properties. For example, all alkaline earth metals are silvery-white-coloured …
Periodic Table of the Elements
When alkali metals react with halogens, halides are formed. All the halides readily dissolve in water except lithium fluoride (LiF). All the halides are ionic in nature except lithium iodide. The chemical reaction of the alkali metals with the halogens is: 2 M + X 2 2 MX (where M represents an alkali metal and X represents a halogen)
Alkali Metals: Elements in the First Column of the Periodic Table
Alkali metals are so called because when alkali metals react with water, they create highly alkaline substances. Alkalinity refers to the pH of the substance, or the ability to neutralize acid. Substances that are highly alkaline can form strong bases able to neutralize acids and maintain a stable pH level.
Group 1: Properties of Alkali Metals
Jim Clark ( Chemguide .uk) Group 1: Properties of Alkali Metals is shared under a license and was authored, remixed, and/or curated by LibreTexts. This page discusses the trends in some atomic and physical properties of the Group 1 elements - lithium, sodium, potassium, rubidium and cesium. Sections below cover the trends in …
Alkali
Alkali. Appearance. In chemistry, an alkali ( / ˈælkəlaɪ /; from Arabic: القلوي, romanized : al-qaly, lit. ''ashes of the saltwort '') is a basic, ionic salt of an alkali metal or an alkaline earth metal. An alkali can also be defined as a base that dissolves in water. A solution of a soluble base has a pH greater than 7.0.
6.10: Alkaline Earth Metals
Alkaline Earth Metals. Group 2 elements are referred to as " alkaline earth " metals (tan column below). The name " alkaline " comes from the fact that compounds of these elements form basic (pH greater than 7) or alkaline solutions when dissolved in water. If the Group 1 elements all have one s s electron in their outer orbital, we can ...
Alkali Metal Properties
The pure element reacts in air or water, so it''s kept in a sealed container. The lone outer shell electrons leads the alkali metal elements to share several common properties: The one outer electron is easily lost, forming the univalent (1+) cation (e.g., Na + ). Alkali metals are typically less dense than other metals.
2.11: Metals, Nonmetals, and Metalloids
Alkaline earth metals are always 2 + (lose both electrons in s subshell) Transition metal ions do not follow an obvious pattern, 2 + is common, and 1 + and 3 + are also observed; Compounds of metals with non-metals tend to be ionic in nature; Most metal oxides are basic oxides and dissolve in water to form metal hydroxides: Metal oxide + water ...
8.3: Group 1, The Alkali Metals
Properties. In metallic form, alkali metals possess a body centered cubic (BCC) structure and are silvery solids, as shown in Figure 8.3.3. Figure 8.3.3. The alkali metals. Notice that most of the samples are either stored in mineral oil or sealed in glass tubes to prevent thier reoxidation by atmospheric oxygen.
4.1: The Alkaline Earth Elements
Reactivity and toxicity. The Group 2 metals have a particular name: the alkaline earth metals. The name is derived from the observation that they have such high melting points (Table (PageIndex {4}).1) that they remain solids (earths) in a fire. Table (PageIndex {4}).2 lists the derivation of the names of the alkali metals.
12.3: Group II
Table 12.3.1 12.3. 1: Properties of the Group IIA Alkaline-Earth Metals. First and second ionization energies for the alkaline earths (corresponding to removal of the first and second valence electrons) are relatively small, but the disruption of an octet by removal of a third electron is far more difficult.
Alkali Metals
Alkali metals have a corresponding [Noble gas] ns 1 electronic configuration. They occupy the first column of the periodic table. Alkali elements are Lithium (Li), Sodium (Na), Potassium (K), Rubidium (Ru), Cesium (Cs) and Francium (Fr), occupying successive periods from first to seven. Francium is a radioactive element with a very low half-life.
Alkali Metal Definition (Chemistry)
Alkali metals are all soft, shiny reactive metals. Although they are soft enough to cut with a knife, exposing a bright surface, the metals react with water and air and quickly tarnish, so the pure metals are stored in an inert atmosphere or under oil to prevent oxidation. All of the metals react vigorously with water, with the energy of the ...
Alkali metal
Alkali metal - Properties, Reactivity, Uses: The alkali metals have the high thermal and electrical conductivity, lustre, ductility, and malleability that are characteristic of metals. Each alkali metal atom has a single electron in its outermost shell. This valence electron is much more weakly bound than those in inner shells. As a result, the alkali …
Alkaline earth metal
The alkaline earth metals are six chemical elements in group 2 of the periodic table.They are beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra). The elements have very similar properties: they are all shiny, silvery-white, somewhat reactive metals at standard temperature and pressure.. Together with helium, these …

Some of the groups have widely-used common names, including the alkali metals (Group 1) and the alkaline earth metals (Group 2) on the far left, and the halogens (Group 17) and the noble gases (Group 18) on the far right. The elements can be broadly divided into metals, nonmetals, and semimetals. Semimetals exhibit properties intermediate ...
8.3.1: Alkali Metals'' Chemical Properties
Because of their tendency to form cations, alkali metals are highly reducing. All react vigorously with water to give hydroxides. 2 M(s) + 2 H2O(l) → 2 M + + 2 OH − + H2(g) (M = = Li, Na, K, Rb, Cs) The reactions are all exothermic and often lead to combustion of the evolved H 2 gas. As a result, while Li usually just fizzes as it reacts ...
