the electrons in the MOST OUTER shell of an atom.

• ion

• proton

• valence electron

• neutron

an atom that is missing or gains extra electrons and therefore is either negatively or positively charged.

• chemical bond

• proton

• ion

• valence electron

a positively charged ion due to the loss of 1 or more electrons

• anion

• ion

• valence electron

• cation

a negatively charged ion due to gaining 1 or more electrons.

• anion

• valence electron

• ion

• cation

a bond formed by the transferring of electrons. This occurs between a metal (loses electrons) and a nonmetal (gains electrons).

NGSS.MS-PS1-5

A bond formed by the sharing of electrons. This occurs between two nonmetals

• Covalent Bond

• Ionic Bond

• Chemical Bond

• Chemical Reaction

This occurs when two or more molecules interact, and the molecules change. Bonds between atoms are broken and created to form new molecules.

• Ionic Bond

• Covalent Bond

• Chemical Bond
