Question

Maximum number of electrons is present in

• A. 2.24 lit. of SO2 at S.T.P
• B. 0.2 moles of NH3
• C. 1.5 gm moles of oxygen
• D. 2 mole atoms of of sulphur

Answer 1

The correct option is D

2 mole atoms of of sulphur

Two moles of sulphur atoms have the maximum number of electrons.
No. of electrons = No. of moles $\times$ Avogadro no $\times$ No. of electrons in a molecule $=2\times N\times 16=32N$
