How many valence electron and helium and hydrogen Hold

2

What is an ion

A charged particle that has either more or fewer electrons than protons

What is an ionic bond

Force of attraction between the opposite charges of the ion in an ionic compound

What is an Covalent bond

Is the attraction that forms between atoms when they share electrons

What is a molecule

The neutral particle that forms as a result of electron sharing

What is nonpolar bond

Covalent bond in which electrons are shared equally by both atoms

What is a polar bond

Electrons are shared unequally resulting in a slightly positive end and a slightly negative end

What is a nonpolar molecule

A molecule that does not have oppositely charged end

What is a polar molecule

Unequal sharing of electrons that result in a slightly positive end and slightly negative end but are overall neutral

What is an oxidation number

Positive or negative number that indicates how many electrons an atom has gained, lost, or shared to become stable

Is hydrogen chloride a polar or nonpolar molecule

Polar molecule

What is a binary compound

Composed of two elements

What is a Polyatomic ion

Positively or negatively charged covalently bonded group of atoms

What is a hydrate

Composed of water attached to its atoms and written into its chemical formula

What is a Chemical bond

The force that holds atoms together in a compound

If atoms share electrons this means it is a
