Question

Calculate the period No. & Group No. of Sulphur in the modern

periodic table​

Answer 1

Answer:

The atomic number of sulphur = 16

The electronic configuration of 16S = 1s2 2s2 2p6 3s2 3p4

⇒ Total number of valence electrons (3s2 3p4) = 6

⇒ As period number is decided by the valence electrons, thus period number of sulphur = 6

⇒ In sulphur, 3 is the highest principal quantum number (n=3), thus group number of sulphur = 3
