Question

1. Write the fundamental particles present in atom with charge and mass?​

Answer 1

Answer:

so here's your answer

Neutrons are located in the nucleus with the protons. Along with protons, they make up almost all of the mass of the atom. The number of neutrons is called the neutron number and can be found by subtracting the proton number from the atomic mass number.

Answer 2

$\sf\colorbox{pink}{⇨ AnsweR ⇦}$

⇨ The fundamental particles present in an atom are electrons and nucleons (protons and neutrons).

⇨ Electrons have an electric charge of −1, which is equal but opposite to the charge of a proton, which is +1 . And neutron is neutral .
