Question

define electrons protons and neutrons​

Answer 1

Answer:

Atoms are made of extremely tiny particles called protons, neutrons, and electrons. Protons and neutrons are in the center of the atom, making up the nucleus. Electrons surround the nucleus. Protons have a positive charge. Electrons have a negative charge.

Answer 2

electron:

Electrons are the negatively charged particles of atom. Together, all of the electrons of an atom create a negative charge that balances the positive charge of the protons in the atomic nucleus. Electrons are extremely small compared to all of the other parts of the atom.

proton:

Protons are composite particles composed of three valence quarks: two up quarks of charge + 23e and one down quark of charge − 13e. ... A fast proton moving through matter will slow by interactions with electrons and nuclei, until it is captured by the electron cloud of an atom.

neutron:

Neutron, neutral subatomic particle that is a constituent of every atomic nucleus except ordinary hydrogen. It has no electric charge and a rest mass equal to 1.67493 × 10−27 kg—marginally greater than that of the proton but nearly 1,839 times greater than that of the electron.
