Chemical bonding

What is the difference between an atom and a compound?

• An atom involves one element, a compound involves the combination of two or more elements.

• An atom is always bigger than a compound.

• They are generally the same.

• An atom is two molecules bonded, a compound is more than two bonded.

Where are the metals found on the periodic table?

• The middle.

• The left side.

• The right side.

• They are in random places.

Where are the non-metals found on the periodic table?

• The middle.

• The left side.

• The right side.

• They are in random places.

What type of bond do we get when we combine a metal and a non-metal?

• A compound.

• A molecule.

• A covalent bond.

• An ionic bond.

What is the number of electrons that atoms want in their outermost energy level?

• 6

• 7

• 8

• 9

• 2

Why don't noble gases react to form bonds with other atoms?

• They are too big.

• They are too small.

• They already have a full outermost energy level.

• They do not have a full outermost energy level.

What is an ion?

• A charged atom.

• A charged group of atoms.

• An uncharged atom.

• An uncharged group of atoms.
