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:

all are false

Explanation:

1. atomic size decreases from left to right across a period
2. ionization potential decreases from left to right across a period
3. electron affinity decrease going down a group
4. electronegativity decrease going down a group

Answer 2

Answer:

B) Ionisation Potential increases from left to right.

Explanation:

More amount of energy is required to remove an electron from the outermost shell
