Sulphur is located in the third period and group 16. The general electronic configuration of group 16 is $ns^{2} np^{4}$ therefore the maximum number of valency electrons in group 16 is 6. The electronic configuration of sulphur is [Ne] $3s^{2} 3p^{4}3d^{0}$ . Sulphur has six valency electrons whereas sulphur can have more than eight electrons in its valency shell as it have an empty d-shell electrons can accumulate in the empty d-shell. The complete d-shell and the $P_{z}$ orbital will be empty. As each orbital can accept 2 electrons, sulphur can have 12 valency electrons in its valency shell.

Answer:

Three chemical elements: hydrogen, oxygen, and helium.

The difference between metals and metalloids is: metalloids have properties in between those of the metals and non-metals and are semiconductors.

The periodic table is organized by the elemts atomic number, it goes from the element with the lowest atomic number (which is hydrogen) to the element with the highest atomic number (oganesson)
