Explanation:
As the charge of all electrons are equal, the repulsive force exerted by each of them is also going to be equal. So, as K has more electrons repulsing its valence electron than Na, it has greater electron shielding.
Answer:
The answer is 7600 nm.
Explanation:
As, Y = 0.25 = [ L ÷ (400 + (L)]
0.95 x 400 + 0.25 [ L] = [ L ]
380.25 = [ L ] - 0.95 [ L ]
= 0.05 [L]
[L] = 380 ÷ 0.05 = 7600nm
