What is electronegativity?

Back

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

Front

What is the difference between ionic size and atomic size?

Back

Ionic size refers to the size of an ion, while atomic size refers to the size of a neutral atom.

What is ionization energy?

Back

Ionization energy is the energy required to remove an electron from an atom in its gaseous state.

Front

What is the periodic trend for ionization energy?

Back
