Ionic Formulas Turning chemistry into algebra

REVIEW We can tell how many electrons an atom will gain or lose by looking at its valence electrons. Metals like to lose electrons. (Cations) – Ex. Na + Nonmetals like to gain electrons. (Anions) – Ex: O 2- All elements try to have a full valence of 8 electrons(OCTET RULE).

REVIEW Cation- is a positively charged ion. How do cations form? – When atoms LOSE electrons they become positive. Anion- is a negatively charged ion. How do anions form? – When atoms GAIN electrons they become negative.

Chemical Bonding A chemical bond is the force of attraction that holds two atoms together. Attractive Force NaCl

Why do elements form chemical bonds? Atoms form chemical bonds in order to fill their outermost energy level with electrons. A full valence causes an atom to be more stable. A full valence consists of 8 valence electrons.

Ionic Bonding Ionic bonds: Metal atoms transfer electrons to nonmetal atoms. Producing oppositely charged ions (cation & anion) which attract each other. Na + + Cl -  NaCl
