an element has atomic number 16. write its electronic configuration, number of valence electrons, valency.

identifythe element . is it matal or non-metal? give reson.

As atomic no. is 16 it will have 16 electrons hence electronic config. 2,8,6
Since it needs only 2 electrons to complete octet it will accept them hence valency 2 and as it is electron acceptor its a non metal.
The element is Sulphur
