2.7 Molecular and Ionic Compounds | Chemistry
The name of a metal ion is the same as the name of the metal atom from which it forms, so Ca 2+ is called a calcium ion. When atoms of nonmetal elements form ions, they generally gain enough electrons to give them the same nuer of electrons as an atom of the next noble gas in the periodic table.
Properties of Hydrogen | Introduction to Chemistry
Hydrogen is available in different forms, such as compressed gaseous hydrogen, liquid hydrogen, and slush hydrogen (composed of liquid and solid), as well as solid and metallic forms. The Hydrogen Atom Many of the hydrogen atom’s chemical properties arise from its small size, such as its propensity to form covalent bonds, flammability, and spontaneous reaction with oxidizing elements.
