The ionization energy increases along a period in periodic table due to increase in:
Correct answer: C. Nuclear charge
- A. No. of positron
- B. No. of neutron
- C. Nuclear charge
- D. No. of electron
- E. Atomic size
Explanation
The correct answer is option (c): Nuclear charge. Ionization energy is the energy required to remove an electron from an atom or ion in its gaseous state. Along a period in the periodic table, the ionization energy generally increases. This increase is primarily due to an increase in the nuclear charge or the number of protons in the nucleus of the atoms.

About s-Block and p-Block Elements
The s and p blocks are studied through their valence-shell configurations, periodic trends and characteristic chemical properties. Work covers the reactions of Group I and Group II elements, the behaviour of Group IV elements, and how atomic size, ionization energy, electronegativity and metallic character change across periods and down groups.
