Front

Define Ionization Energy.

Back

The energy required to remove an electron from an atom in its gaseous state.

Front

Define Electronegativity.

Back

A measure of the tendency of an atom to attract a bonding pair of electrons.

Front

What is Electron Affinity?

Back

The amount of energy released when an electron is added to a neutral atom to form a negative ion.

Front

What is Oxidation Number?

Back

The charge of an atom in a compound, indicating the number of electrons lost or gained.

Front

What is the significance of the Periodic Table?

Back

It organizes elements based on their atomic number, electron configurations, and recurring chemical properties.
