☆We are going that elements P,Q,R and S, have atomatic numbers 11, 15, 17, and 18,
☆ We have to find non elements in given elements
☆ We know that atomic mubers of sodium = 11,
☆Therefore , P is Sodiume .
☆ Sodiume is metal and non metal .
☆ We know that atomic nimber of phosphours,P: 15
☆ Therefore Q, is phousphours .
☆ It is non metal becouse it is reqiuerd 3 electrons to complete their otict atomic Number
of chloride : 17,
☆Therefore element R, is chlorides .
☆ it is non metal it required one electron to complete their octect Atomic numbers of
organes : 18
i hope its helpfull....
