Chemical Bonds and Reactions

chemical shorthand that uses symbols to tell what elements are in a compound and their ratios

• chemical formula

• chemical equation

• chemical bond

• chemical symbol

force that holds atoms together in a compound

• chemical equation

• chemical reaction

• chemical bond

• catalyst

charged particle that has either more or fewer electrons than protons

• molecule

• isotope

• ion

• allotrope

the force of attraction between the opposite charges of the ions in an ionic compound

• covalent bond

• metallic bond

• opposing bond

• ionic bond

attraction formed between atoms when they share electrons

• ionic bond

• covalent bond

• metallic bond

• cooperative bond

a neutral particle that forms as a result of electron sharing among atoms

• ion

• molecule

• neutron

• quark

a covalent bond in which electrons are shared equally by both atoms

• polar bond

• ionic bond

• metallic bond

• nonpolar bond

a covalent bond in which the electrons are not shared equally, resulting in a slightly positive end and a slightly negative end

• nonpolar bond

• polar bond

• metallic bond

• ionic bond

a neutral molecule in which unequal electron sharing results a slightly positive end and a slightly negative end

• polar molecule

• nonpolar molecule

• anion

• cation

molecule that shares electrons equally and does not have oppositely charged ends

• polar molecule

• anion

• cation

• nonpolar molecule
