1.	Which of the following indicates natural abundance of neon – 20 isotope? (A) 90.92 u (B) 90.92 % (C) 90.92 gm mol⁻¹ (D) 90.92 × 0.012 kg of ¹²C
Answer» udent,◆ 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.Neon-20 (Abundance = 90.48 %)Neon-21 (Abundance = 0.27 %)Neon-22 (Abundance = 9.25 %)Thanks DEAR. Hope this helps you...
