What type of atomsmetal atoms only, nonmetals atoms only, or a combination of metal and nonmetal atomsare involved in this ionic interaction? Refer to your periodic table.

What happens to the metal atom's valence electron(s) when an ionic interaction forms with a nonmetal atom?

The lithium +1 ion has the same number of valence electrons as what noble gas?

The fluoride -1 ion has the same number of valence electrons as what noble gas? (Note: "Fluoride" is the name given to the flourine -1 ion.)

Lithium atoms are ______________ (larger than, smaller than, or the same size as) lithium ions.

Fluorine atoms are ______________(larger than, smaller than, or the same size as) fluoride ions.

Why do you think compounds formed by these interactions are called ionic?

Why would there an attractive force between the electrons and the nuclei?

What determines the bond length of a particular bond?

Energy is always released from the system to the surroundings when a bond is ______________(formed or broken).

Atoms that are separated have ____________________ (higher, lower, or the same) potential energy than the atoms when they are "bonded".

The covalent bond is due to the balance of the _____________________ forces and ______________________ forces.

S4. The shell model is a useful representation for determining bonds, but it doesn't capture all aspects of the electrons.
