2.4 Three types of chemical bonds are ionic, covalent, and hydrogen

a molecule in which one side of the molecule is slightly negative and the opposite side is slightly positive

polar molecule

example of an ionic bond

sodium chloride

the attractive force that holds atoms or ions together

chemical bond

an ion with a negative charge

anion

an ion with a positive charge

cation

A chemical bond that involves sharing a pair of electrons between atoms in a molecule

covalent bond

A molecule that has two poles

dipole

a grouping of electrons surrounding the nucleus of an atom

electron shell

attraction of an atom for an electron in a bond (when covalent bond is already formed)

electronegativity

atoms with one or two valence shell electrons

electropositive

What kind of bonds form between water molecules?

hydrogen bonds

weak attraction between a hydrogen atom and another atom

hydrogen bonds

A charged atom

ion

Formed when one or more electrons are transferred from one atom to another

ionic bond

what are the types of chemical bonds

ionic, covalent, hydrogen

a molecule that does not have oppositely charged ends

nonpolar molecule

States that atoms lose, gain or share electrons in order to acquire a full set of eight valence electrons

octet rule

outermost electron shell

valence shell

example of a covalent bond

water

what is an example of a dipole

water
