Question

WRite the electronic configuration of ti4+ ion

Answer 1

Titanium has the configuration [Ar] 4s2 3d2. Ti^2+ is [Ar] 3d2, Ti^3+ is [Ar] 3d1 and Ti^4+ is [Ar]. The 3p electrons are left alone in all of these ions. I think you are making an error in your configuration assignments.

Answer 2

Electronic configuration of $Ti^{4+}$ ion.

• To write electronic configuration of $Ti^{4+}$, first the electronic configuration of element Titanium element must be written.
• To write it, the number of electrons present in Titanium must be known.
• We know that the atomic number represents the total number of electrons present in it.
• As the atomic number of Titanium is 22, it has 22 electrons. So the electronic configuration of titanium is $1s^22s^22p^63s^23p^64s^23d^2$.
• As $1s^22s^22p^63s^23p^6$ is electronic configuration of Nobel gas argon, it can be represented as [Ar]$3d^24s^2$.
• $Ti^{4+}$means that the titanium ion has lost four electrons and thus its electronic configuration will be [Ar]$3d^04s^0$.
