Question 31

Atomic Structure

An element will readily form an electrovalent compound if its electron configuration is

  1. A.2, 8, 1
  2. B.2, 8, 4
  3. C.2, 8, 8
  4. D.2, 8, 5
Show the answer and explanation

Answer: A (2, 8, 1)

Explanation

An atom with 2, 8, 1 (sodium) easily loses its single outer electron to form Na+, so it readily forms ionic (electrovalent) compounds.
