a chemical bond that involves the sharing of electrons to form electron pairs between atoms

The interatomic linkage that results from the sharing of an electron pair between two atoms.

when an entity contains two distinct and opposite poles that can either attract or repel each other.

formed from oppositely charged ions are held together in a crystal

1. a negatively charged ion, i.e. one that would be attracted to the anode in electrolysis.

a positively charged ion, i.e. one that would be attracted to the cathode in electrolysis

measure of the amount of energy needed to break apart one mole of covalently bonded gases.

a thing that is composed of two or more separate elements

a substance made by mixing other substances together.

how many valence electrons do most atoms need to be stable

what 2 elements only need 2 valence electrons to be most stable

what causes a molecule to be polar

is water a polar molecule

What will an atoms charge be if it gains an electron

What will an atoms charge be if it loses an electron

what will happen if one ion is positive and another ion is negative

what happens if 2 things have the same charge

how can you help which columbs in the periodic table lose or gain electrons
