Question

With reference to the variation of properties in
the Periodic Table, which of the following is generally
true?
(a) Atomic size increases from left to right across a
period.
(b) Ionization potential increases from left to right
across a period.
(c) Electron affinity increases going down a group.
(d) Electro-negativity increases going down a group.​

Answer 1

Answer:

ç is correct answer

Answer 2

Answer:

b)Ionization potential increases from left to right

across a period

Explanation:

Ionization energy is the energy required to remove an electron from valence shell. Since the atomic size decreases across a period, it is difficult to remove an electron from last shell and thus would require high amount of Ionization energy .
