Define Ionization Energy

• The energy required to convert an ion back to a neutral atom

• The energy required to remove one mole of electrons from one mole of gaseous atoms

• The energy required to add one mole of electrons from one mole of gaseous atoms

• The energy required to combine two or more ions together

Define Electron Affinity

• The energy required to convert a cation to an anion

• The energy required to convert an anion to a cation

• The energy required to combine negative ion with a cation

• the change in energy (in kJ/mole) of a neutral atom (in the gaseous phase) when an electron is added to the atom to form a negative ion.

Define Electronegativity

• It is the energy required to convert the charge of an electron from negative to positive

• It is the measurement of the negativity of an electron

• electronegativity is the tendency of an atom to attract electrons in a molecule

• None of the above

Define Melting Point

• Temperature at which an atom in the solid state will melt to liquid.

• Temperature at which an atom in the liquid state will melt to gas.

• Temperature at which an atom in the liquid state will convert back to solid.

• Temperature at which an atom in the gas state will convert back to solid.

• Temperature at which an atom in the gas state we convert back to liquid.
