Question

The number of valence electron 'V' and valency 'M' of an element having atomic number 14 is

• A. V = 8
  M = 2
• B. V = 6
  M = 6
• C. V = 4
  M = 2
• D. V = 4
  M = 4

Answer 1

The correct option is D V = 4

M = 4
The element with atomic number 14 has the electronic configuration 2, 8, 4. Thus, it has four valence electrons (V) and valency of four (M).
Hence, the correct answer is option (b).
