Question

The charge of a single proton is 1.60 × 10–19 C. What is the nuclear charge of an atom of boron (B)?

Answer 1

`q=8* 10^(-19)\ C`

Step-by-step explanation:

Given that,

The charge of a single proton is
`1.6* 10^(-19)\ C`

There are 5 protons in the nucleus. The nuclear charge of an atom of boron is given by :

`q=5* 1.6* 10^(-19)\\\\q=8* 10^(-19)\ C`

So, the required charge is
`8* 10^(-19)\ C`.
