Question

The relative charge on an electron, proton and a neutron are:

• A. +1, +1, 0
• B. -1, +1, 0
• C. -1, 0, +1
• D. 0, +1, -1

Answer 1

The correct option is B -1, +1, 0

An electron has an absolute charge of $-1.602\times {10}^{-19}C$ and a proton has a charge of
$+1.602\times {10}^{-19}$ C and a neutron has no charge.
So, the relative charge on an electron, proton and a neutron respectively are -1, +1, 0.
