(b) krypton and ozone
(c) phosphorus and sulphur
(d) krypton and sulphur

Answer 1

Hi mate.

.answer ...Krypton and sulphur.

.Out of them Kr atomicity is the lowest that is 2 and sulphur atomicity is highest that is 8

Thanks...

Answer 2

Answer is Option (a)

Explanation:

• Krypton has Atomicity of 1 (One)

• Sulphur has atomicity of 8 (Eight)

${\textrm}Atomicity_{Sulphur}$ >  ${\textrm} Aromicity_{Krypton}{\text}$

• Atomicity is defined as no. of atoms in a stable molecule.

Example -  

One molecule of NaOH -- there is -

• 1 Sodium Atom (Na)

• 1 Oxygen Atom (O) &  

• 1 Hydrogen Atom (H)

So, Atomicity of (NaOH) or Sodium Hydroxide is 3.
