Answer 2

Hi there dear user ^_^

◇ PLEASANT WEDNESDAY ◇

《 ANSWER 》

Subatomic particles are as follows:

> Electron - A negatively charged particle revolving around the nucleus present inside every atom of an element.
▪Relative mass => 1/1840 u
▪Absolute mass => 9 × 10^-28 grams
▪Relative charge => -1
▪Absolute charge => 1.6 × 10^-19 coloumb of negative charge

> Proton - A positively charged particle present inside the nucleus.
▪Relative mass => 1 u
▪Absolute mass => 1.6 × 10^-24 grams
▪Relative charge => +1
▪Absolute charge => 1.6 × 10^-19 coloumb of positive charge

> Neutron - A neutral particle. In other words, neutrons are those particles with no charge present inside every atom of an element except hydrogen.
▪Relative mass => 1 u
▪Absolute mass => 1.6 × 10^-19

(The mass of a neutron is equal to the mass of a proton.)

Hope it helps you out ^_^
