What is the identity of the element with the electron configuration of 1s22s22p63s23p63d104s2?

Answer : The element is, Zinc.

Explanation :

Electronic configuration : It is defined as the representation of electrons around the nucleus of an atom.

Number of electrons in an atom are determined by the electronic configuration.

The given electronic configuration is:

The total number of electrons are = 2+2+6+2+6+10+2 = 30

As we know that,

Atomic number is defined as the number of protons or number of electrons.

Atomic number = number of protons = number of electrons

As, number of electrons = 30

So, atomic number = 30

Thus, the element will be zinc.

3 hours because it is a decent distance.

the answer is na (sodium)
