A Nonmetal.

Sodium loses one electron when it reacts with a nonmetal.

A Nonmetal.
The nonmetals share the atoms when reacting with each other.
They become anions, with negative electrical charge.
when.... 1- a metal forms bond with metals. 2- a nonmetal with nonmetal nonmetal. 3- or atoms having electronegativities difference less than 1.7 (with exeption of HF having E.N diff. 1.9)...... or Jefferson lab says: when pairs of electrons are shared between two nonmetal atoms or when pairs of electrons are shared between two nonmetl atoms
Various things. If it is a nonmetal and nonmetal it going to be a covalent bond. If it is a metal and nonmetal it is going to be an ionic bond. If it is a metal and metal then it is a metallic bond.
These are covalent compounds.
