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
