Question

In the representation of a neutron: ${}_0{n}^1$ 1 represents the mass and 0 represents the:

• A. electrical charge
• B. magnetic charge
• C. atomic number
• D. mass number

Answer 1

The correct option is A electrical charge

_{${}_0{n}^1$} represents a neutron for simplicity. The subscript 0 represents the charge and the superscript 1 represents the mass of neutrons in a.m.u(atomic mass unit). A neutron is a sub atomic particle of an atom which possesses no charge and mass is almost equal to one hydrogen atom.
