14 hours ago · v. t. e. Nonmetals are chemical elements that mostly lack distinctive metallic properties. They range from colorless gases like hydrogen to shiny crystals like iodine. Physically, they are usually lighter (less dense) than metals; brittle or crumbly if solid; and often poor conductors of heat and electricity.
Nonmetals usually have a high electron affinity and ionization energy value because they have such a small atomic radius. Nonmetal elements usually form simple covalently bonded compounds. These structures contain just a few atoms, and they do not generate strong intermolecular forces of attraction.

3 days ago · The alkali metals include the elements lithium, sodium, potassium, rubidium, cesium, and francium. Hydrogen is also found in the leftmost column of the periodic table, but it is not classed as an alkali metal or group one metal element because it forms a nonmetal gas under standard conditions.
