Question

the first (IE1) and the second (IE2) ionisation enthalpy (KJ mol-1)of a few element disignated by roman numeral are shown below:. <br /><br />element. IE1. IE2<br /><br />I. 2372. 5251<br />II. 520. 7300. <br />III. 900. 1760<br /><br />which of the above element is likely to be<br /><br />(i) A reactive non-metal<br />(ii)A noble gas <br />(iii)A metal that forms a stable binary halide of the formulae AX2 (X=halogen)​

Answer 1

Answer:

Explanation:

I. is Noble gas (due to high first IE)

II. is a metal (due to low first IE and also unipositive due to high 2nd IE)
