Q

What is an ionic bond?

A

Attraction between two oppositely charged ions. Compounds are electrically neutral (ions bond in a way that balance the changes) They are reactions between metals adn non metals.

Q

How to make an ionic bond

A

Balance to equal to 8 electrons. If one atom has two protons and two electrons it must give two electrons away to balance. (Protons are in the nucleus) Now there are +2 > 0. The atom has more protons so it is positive.
If one atom has six protons and six electrons it must gain two electrons (-) to balance. (Protons are in the nucleus) Now there are +6 > -8. The atom has more electrons so it is negative.

Q

How to know what atoms are metals and nonmetals?

A

A metal atom holds on to its valence electrons loosely. It usually atoms with 1, 2, 3 valence electrons. For nonmetals they hold on to it tightly. To balance the atom you don’t give away atoms. They have 6,7,8 valence electrons.
