Zinc
Explanation:
Electron configuration:
1s² 2s² 2p⁶ 3s² 3p⁶ 3d¹⁰ 4s²
To decipher this atom, we must understand what each of the letters and number represents;
1s²
1 is the principal quantum number
s is the azimuthal number or the subshell
2 superscript is the number of electrons
Using the number of electrons, we can deduced the atom:
2+2+6+2+6+10+2 = 30 electrons
The element with 30 electrons on the periodic table is Zinc
