What is an element?

• A type of compound found in living organisms.
• An impure substance that can be broken down into simpler substances by chemical means.

• A form of energy that can be converted into matter.
• A pure substance that cannot be broken down into simpler substances by chemical means.

What is a compound?

• A compound is an element that is formed when two chemical substances are chemically bonded together.

• A group of two or more atoms, attracted by relatively strong forces or bonds; in a fixed ratio

• A compound is a substance formed when three or more chemical elements are chemically bonded together.

Define boiling point

• The temperature at which the vapor pressure of a substance equals atmospheric pressure

• The temperature at which the vapor pressure of a substance is greater than atmospheric pressure

• The temperature at which the vapor pressure of a substance is less than atmospheric pressure

• The temperature at which a gas changes into a liquid at a given pressure.

What is electronegativity?

• Electronegativity is a measure of the tendency of an atom to attract bonding electrons

• Electronegativity is the measure of an atom's size in a chemical bond.
• Electronegativity is the number of electrons an atom can lose in a chemical reaction.
• The amount of energy released when an atom in the gaseous phase gains an electron to form a negative ion
