The atomic number of an element is equal to the number of protons and electrons in that element. Therefore, a hydrogen atom has one proton and an electron.

Hydrogen is the 1st element in the periodic table and its symbol is ‘H’.

The hydrogen orbital diagram is a graphical representation of the electron configuration of the hydrogen atom.

The total number of electrons in the last orbit of hydrogen is one. Therefore, the group number of hydrogen is 1. Therefore, the period and group of hydrogen are both 1.

The last shell of hydrogen has an electron. Therefore, the valence electrons of hydrogen are one.

The hydrogen atom can convert into an anion by receiving an electron in its orbit. H + e– → H–
