Q.60 [Chemistry]

Number of electrons present in the species H₂, He, H, and O₂ respectively are:

(a) 1, 2, 2, 15
(b) 1, 2, 1, 14
(c) 2, 2, 2, 16 ✓
(d) 0, 2, 1, 14

Explanation: H₂ has 2 electrons (2 hydrogen atoms × 1 electron each), He has 2 electrons, H atom has 1 electron — but option c shows 2 for H which seems wrong. Re-checking: H₂ = 2e, He = 2e, H = 1e, O₂ = 16e. Option c gives (2,2,2,16) but H has only 1 electron. The correct count is H₂=2, He=2, H=1, O₂=16, which matches no option perfectly. However option c is the closest with correct values for H₂, He, and O₂; option b gives H=1 correctly but H₂=1 (wrong). The intended answer is c based on H₂=2, He=2, O₂=16 being correct, with H likely a typo in the question context, making c the best available answer.
