Question

write the condensed (noble - gas) electron configuration of sn.
for multi - digit superscripts or coefficients, use each number in succession.
kr5s²5p⁶5d

Explanation:

Step1: Determine the atomic number of Sn

Tin (Sn) has an atomic number of 50.

Step2: Find the noble - gas core

The noble gas before Sn in the periodic table is Kr (atomic number 36).

Step3: Fill the remaining electrons

After [Kr], we need to fill \(50 - 36=14\) electrons. The order of filling is \(5s^{2}4d^{10}5p^{2}\)

Answer:

\([Kr]5s^{2}4d^{10}5p^{2}\)
