Answer 1

Dear Student,

◆ Answer -

(B) 90.92 %

● Explanation -

• Natural abundance of isotopes is written in percentage, hence natural abundance of Neon-20 must be option (B) 90.92 %.
• Neon has 3 isotopes - neon-20, neon-21 and neon-22.

1. Neon-20 (Abundance = 90.48 %)
2. Neon-21 (Abundance = 0.27 %)
3. Neon-22 (Abundance = 9.25 %)

Thanks dear. Hope this helps you...
