Give reason - The oxidising power of elements increases from left to right along a period.

Give reasons why ? The oxidizing nature of elements increases on moving from left to right along a period in the periodic table.

Give reason : Ionisation polential increases across a period-left to right.

In the second period of periodic table, the ionisation potential of elements increases from left to right because of

Explain the trend in general of ionisation potential of elements on moving from left to right across a period

(a) Define the following terms: (i) Valency, (ii) Atomic size (b) How do the valency and the atomic size of the element vary while going from left to right along a period in the modern periodic table?

Explain the following a) Electronegatively of elements increase on moving from left to right in the periodic table. b) Ionisation enthalpy decrease in a group from top to bottom.

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 on going down a group. D: Electronegativity increases on going down a group.

Statement-1 : First electron gain enthalpy is alway -ve for an element. Statement-2 : Magnitude of electron gain enthalpy irregularly increases from left to right in a period.

Ionisation potential increases in a period from left to right because

Give reason: I.P. of elements increases across a period,
