The nutrition label on a bag of potato chips lists having 65 mg of sodium in it. Sodium reacts violently when it comes in contact with water. Why, then, do you not explode when eating a bag of potato chips with your lunch?
the sodium the bag is referring to is actually a compound, sodium chloride, which is a chemical compound and not pure sodium. Because it's chemically combined, it's properties have changed and it is not explosive as a result (table salt)

Explain the difference between an ionic bond and a polar covalent bond.
Ionic: the electronegativity difference is big enough so one element takes an electron from the other.
Polar Covalent: the electronegativity difference is smaller and electrons are shared.
