Question

at the centre of an atom protons and neutrons form a tiny Central core called an electron .true or false​

Answer 1

✤ The statement is false❌

At the centre of an atom, protons and neutrons form a tiny centre core known as Nucleus. Electrons are other subatomic particles which revolves around the nucleus.

Explanation:

The electrons are negatively charged particles which are attracted by the nucleus containing protons that is positively charged. But, Electrons are made to revolve around the nucleus because they participate in formation of bonds between different elements. So, They move faster in order to balance the nuclear force and centripetal force$.$

Let's know more about other subatomic particles that are electron, neutrons and protons,

• Among the subatomic particles, Electron was first discovered followed by proton. Later, Neutron was also discovered.

1. Electrons- JJ Thompson
2. Protons- Goldstein
3. Neutrons- Chadwick

• Atoms of elements are electrically neutral, and they don't have any net charge. That means, ☸ Number of electrons = Number of protons.

• Mass of Electrons is approx. 9.1 × 10‐²⁸ g which is nearly negligible. Mass of proton is 1.672 × 10‐²⁴ g and mass of neutron is nearly same as that of mass of proton that is 1.675 × 10-²⁴ g.

• Charge of electron is -1.602 × 10‐¹⁹ coulomb, charge of proton is +1.602 × 10-¹⁹ coulomb and charge of neutron is 0
