Question

What is the electron configuration of ${\mathrm{Ti}}^{2+}$?

Answer 1

Titanium(Ti):

• Titanium is a d-block element having atomic number 22.
• The chemical symbol of Chromium is ‘Ti’

Electronic configuration of d-block

• In general, the electronic configuration of these elements is $(\mathrm{n}-1){\mathrm{d}}^{1-10}{\mathrm{ns}}^{1-2}$.
• Here, (n–1) stands for the inner $d$orbitals which may have one to ten electrons, and the outermost $\mathrm{n}s$ orbital may have one or two electrons.

Electronic configuration of ${\mathrm{Ti}}^{2+}$:

• The electron configuration of Titanium is $\left[\mathrm{Ar}\right]3{\mathrm{d}}^{2}4{\mathrm{s}}^2$.
• ${\mathrm{Ti}}^{2+}$ is formed by losing two-electrons by the Titanium atom in the neutral state.
• The electron configuration of ${\mathrm{Ti}}^{2+}$ will be $\left[\mathrm{Ar}\right]3{\mathrm{d}}^2$.
