Question

What is the element with an electron configuration of 1s22s22p63s23p64s23d2?

Answer 1

Since Z=22. Hence the element is Titanium.

Answer 2

The element is Ti.

• The given electronic configuration of an element is
• ${1s}^{2} {2s}^{2} {2p}^{6} {3s}^{2} {3p}^{6} {4s}^{2} {3d}^{2}$
• Thus its atomic number is 22.
• So, the element is Ti.
• Ti is a 3d block element. It is also called the transition element.
• Ti has an atomic number of 22 and it has two electrons in its 3d subshell.
• The valance electrons of Ti is 4.
