Question

1. Name the three particles of the atom and their respective charges:

Answer 1

Protons have a positive electrical charge, so they are often represented with the mark of a "+" sign. Neutrons have no electrical charge and are said to help hold the protons together (protons are positively charged particles and should repel each other). The electron is a subatomic particle, symbol
e−
or
β−
, with a negative elementary electric charge.

Answer 2

Electrons: Negative charge
Protons: Positive charge
Neutrons: No charge

Hope this helped.
