Question

among a species which of them have maximum Zeff

Answer 1

SN 4+ is your answer

Answer 2

Answer:

Sn⁺⁴ will have maximum Z(eff). i.e.option(B).

Explanation:

• The attractive positive charge of nuclear protons acting on valence electrons is known as an effective nuclear charge.
• Due to the shielding effect, the effective nuclear charge is always smaller than the total amount of protons in a nucleus.
• All other periodic table trends lag those of effective nuclear charge.
• The equation: may be used to approximate the effective nuclear charge.

                 Z - S = Z(eff)

Where

S=the number of shielding electrons

Z=the atomic number

• The element having a more positive charge shows more Z(eff).

So, the correct answer among the given options is (B) Sn⁺⁴.
