Carbon belongs to the second period and Group 14. Silicon belongs to the third period and Group 14. If atomic number of carbon is 6, the atomic number of silicon is
7
14
24
16

Academic Chemistry NCERT Class 10

Correct Answer: (b) 14

Explanation: Carbon has atomic no. 6 and the next element has 8 electrons added to 6 which is 14 so silicon has atomic no. 14.
