Effective nuclear charg for nitrogen is Zeff (3.83)

Answer 2

Answer:

the effective nuclear charge felt by the 1s electron of nitrogen atom is 5.6.

Explanation:

The electronic configuration of nitrogen is, $1s^2 2s^2 2p^3$.

The value of the screening constant is,

$\sigma=(0.35\times4)+(0.85\times2)\\\sigma=3.10$

Again, The value of effective nuclear charge is,

$Z^*=Z-\sigma$

Substitute the values in the given equation,

$Z^*=7-3.10\\ Z^*=3.90$

Now, the value of the screening constant for 1s orbital is,

$\sigma=(0.35\times4)\\\sigma=1.4$

Again, The value of effective nuclear charge is,

$Z^*=Z-\sigma$

Substitute the values in the given equation,

$Z^*=7-1.4\\ Z^*=5.6$

Hence, The value of effective nuclear charge for 1s orbital is, 5.6.
