What are the three properties of alkali metals?

What are the three properties of alkali metals?

Physical properties. 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.

What are the chemical properties of Group 2 elements?

All the elements in Group 2 have two electrons in their valence shells, giving them an oxidation state of +2. Covers the elements beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr) and barium (Ba).

What are the physical and chemical properties of transition metals?

The transition metals have the following physical properties in common:

  • they are good conductors of heat and electricity.
  • they can be hammered or bent into shape easily.
  • they have high melting points (but mercury is a liquid at room temperature)
  • they are usually hard and tough.
  • they have high densities.

What are the properties that make alkaline earth metals unique?

The Alkaline Earth Metals Properties of Alkaline Earth Metals. The alkaline earth metals comprise the group 2 elements. Reactions of Alkaline Earth Metals. All the alkaline earth metals have two electrons in their valence shell, so they lose two electrons to form cations with a 2+ charge. Alkaline Earth Metal Compounds. Radioactivity. Occurrence in Nature.

What are the physical properties of alkali earth metals?

Physical properties. 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.

Which elements are the alkaline earth metals?

Alkaline earth metals are metals that are found in Group II of the periodic table. Six elements such as beryllium, magnesium, calcium, strontium, barium, and radium are placed in this group.

What are the three properties of the alkali metals?

Chemical Properties of Alkali Metals Hydrides: Alkali metals react with hydrogen at higher temperatures to form metallic hydrides. Nitrides and Phosphides: Alkali metals can react with even atmospheric nitrogen to form nitrides. Oxides: Alkali metals react with atmospheric oxygen and get tarnished of their shining nature.
