Question

Which of the two will be chemically more reactive, Sulphur(S) with atomic number 16 or Chlorine (Cl) with atomic number 17?

Answer 1

Answer:

Chlorine

Explanation:

Chlorine is more reactive because it only needs to lose one electron to make it stable and sulphur needs to lose two to become stable. Thus, chlorine is more reactive than sulphur

Answer 2

Answer:

chlorine is more reactive than sulphur

Explanation:

1)in the periodic table they are on the same period

2)we know atomic size decreases from left to right within a period so

3)chlorine size is small with big atomic no. compare to sulphur

4)thus more is the nuclear pull

5)so cl is more electronegative than sulphur
