Question

Which of the following position of elements have same number of valence electrons as that of element of atomic number of 6?

• A. Group 14 and period 3
• B. Group 14 and period 4
• C. Group 6 and period 4
• D. Group 14 and period 5

Answer 1

Answer: (A), (B), (D)

The correct options are
A Group 14 and period 3
B Group 14 and period 4
D Group 14 and period 5

An element having atomic number 6 has an electronic configuration (2,4) and it is carbon which has 4 valence electron and is member of group 14 in the periodic table. All the elements in this group have a similar electronic configuration and the same number of valence electron.

Hence, option A, B and D are correct.
