Question

Tin forms an ion with a 2+ charge. What is the Electron configuration of this ion?

Answer 1

STEP-BY-STEP EXPLANATION

What to find? The electronic configuration of tin ion

Tin is an element with an atomic number of 50.

NB: Atomic number = number of proton

Hence, the number of proton of tin = 50

$Sn^{2+}$

The above tin ion means it has lost two electrons, which make it has a total electron of 48

To write the electronic configuration of tin ion, we will be using the SPDF Notation

spdf are names given to orbitals that hold electrons in atoms.

s - orbital

p- orbital

d- orbital

f -orbital

$\begin{gathered} \text{Electronic configuration of Sn}^{2+}\text{ is written below} \\ 1s^22s^22p^63s^23p^64s^23d^{10}4p^65s^24d^{10} \end{gathered}$
