among the following which increases in period option shielding effect
Answers
Both nuclear charge and reducing property increases in period due to following reasons:-
- In an atom electrons protects each other from the attraction of the nucleus. So, In the atom the decrease in the pull of nucleus of an electron with more than one electron shell can described as shielding effect.
- When we move left to right in period the shielding effect keep on decreasing due to increase in atomic number as shielding effect is greater with the increase in electron shell and I period there is no change in shell.
- When we move left to right in period the nuclear charge increases due to decrease in atoms size .
- When we move left to right in period the electro positivity decreases due to increase in ionization energy.
- When we move left to right in period the reducing property increases as attractive nuclear force increases.
