Question 28

An ion contains 16 protons and has an overall relative charge of +3. A proton contributes +1 to the total relative charge. An electron contributes -1 and has relative mass 11840\displaystyle \frac{1}{1840}18401​.

Which gives the number of electrons in the ion and their combined relative mass?

[1]
A

19 electrons; combined relative mass 191840\frac{19}{1840}184019​.

B

3 electrons; combined relative mass 31840\frac{3}{1840}18403​.

C

13 electrons; combined relative mass 131840\frac{13}{1840}184013​.

D

13 electrons; combined relative mass 11840\frac{1}{1840}18401​.
