Which is the electron configuration for zinc? 1s22s22p63s23p64s23d8 1s22s22p63s23p64s13d10 1s22s22p53s23p64s23d10 1s22s22p63s23p64s23d10

The electron configuration for zinc  is

1s2 2s2 2p6 3s2 3p6 4s2 3d10

Explanation

zinc  Electron  configuration  is the distribution  of electrons  of zinc atom  in atomic  orbitals.   Zinc  is  in atomic number 30  in periodic table .

Atomic number of an atom  is determined  by  number of protons  it have.

The  number  of protons is equal to number of electrons.

Since  zinc is  in atomic number 30  it has 30 protons   and hence  30 electrons.

Therefore  the distribution  of the 30 zinc electrons  is   1s2 2s2 2p6 3s2 3p6 4s2 3d10.

According to Aufbau  Principle electron fill the atomic  orbital  of lower  energy level before  occupying higher  energy level.

for  example 1s   shell is first filled before 2s   sub shell.

Note:  The s  orbital  can hold a maximum of 2 electrons

                P  orbital can  hold a maximum  of 6  electrons

               d orbital  can hold  a maximum of 10 electrons

d

Explanation:

the correct option is c.

isotopes refers to different forms of the same element with the same atomic number but different mass number as a result of difference in their neutron numbers. isotopes have different relative atomic mass but share the same chemical properties.
