Question

9. For sulphur, Z = 16 and for chlorine Z
77. Which of them will have atoms
of a smaller size?​

Answer 1

Z = 17 for chlorine

The size of chlorine is smaller than that of sulphur and its atom needs only one electron to have noble gas electronic configuration while sulphur atom needs two electrons. Therefore, chlorine has greater attraction for electrons than sulphur. It is more electronegative than sulphur.
