Question

For the isotope 6C13, the number of neutrons is:
  1. 7
  2. 6
  3. 19
  4. 13

A
7
B
19
C
13
D
6
Solution
Verified by Toppr

In this structure 6 represents atomic number that is the number of electrons or the number of protons and 13 represents the mass number (A). The number of neutrons (N) = mass number (A) − no. of electron or no. of proton. Hence N=136=7.
