Answer:

The effective nuclear charge for a 2nd row electron in Sulfur is +8

Explanation:

Zeff = Z (# of protons) - S (# of shielded electrons)

Since there are 8 electrons in the first and second rows combined, there are 8 shielding electrons.

The number of protons in Sulfur is 16.

Therefore,

Zeff = 16 - 8

Zeff = 8

(It's been awhile, so I am not 100% sure)

The effective nuclear charge for a 2nd row electron in sulfur is 14.

Sulfur has 16 atomic number means 16 number of protons and we know that in the first shell or orbit 2 electrons are present which produces a shielding effect due to its fast motion.

Its 2s electrons are shielded only by the two 1s electrons, therefore the second row electron experience an effective nuclear charge i.e. Z effective = 16 − 2 = 14 so we can conclude that the effective nuclear charge for a 2nd row electron in sulfur is 14.
