Question

Which of the following elements has the strongest ionization energy: Mg or Cl? Define ionization

Answer 1

Answer:

Cl

Explanation:

The element Cl will have the strongest ionization energy from the given choices. Most non-metals have higher ionization energy compared to metals.

Ionization energy is the energy required to remove the most loosely held electron from the gaseous phase of an atom.

• As you go from left to right on the periodic table, it increases progressive
• From top to bottom, the ionization energy reduces significantly.
• The attractive force between the protons in the nucleus and the electrons plays a very important role.
• In metals, they have very large atomic radius, the attractive force on the outer electrons is very weak.
• This is not the case in non-metals
