Question

The energy needed to remove an electron from an atom is called_____. ionization energy electronegativity electron affinity polarity

Answer 1

The energy needed to remove an electron from an atom is called ionization energy.

Answer 2

Answer: The correct answer is ionization energy.

Explanation:

Ionization energy is defined as the amount of energy required to remove an electron from an isolated gaseous atom to form a positive ion.

Electronegativity is defined as the property of an atom to attract the shared pair of electron towards itself when a bond is being formed.

Electron affinity is defined as the amount of energy released when an electron is added to an isolated gaseous atom to form a negative ion.

Polarity is defined as the separation of electric charge with in the molecule. This leads to the formation of positively charge end and a negatively charged end.

From the above information, the correct answer is ionization energy.
