ii) Electron affinity

b) An element has the atomic number 16. State (3)

i) The period to which its belongs.

ii) The number of valence electrons in its atom.

iii) Whether it is a metal or non-metal.​

Answer 1

Answer:

Explanation:

a) 1)  Ionisation potential is the minimum amount of energy required to remove an electron from an isolated neutral gaseous atom.

   2) Electron affinity is the amount of energy released by the addition of electrons to an isolated neutral gaseous atom.

b) 1)  Second period

   2) 6 valence electrons

   3)  Element 16 is sulfur which is a non-metal
