Most of the mass of an atom is concentrated in

Atoms of elements are made up mainly of protons, electrons and neutrons. a) Which of these particles are present in the nucleus of atoms? b) The discovery of which particle is related to the scientist .J. J. Thomson? c) Name the positively. charged particles? d) Name the scientist who proved that most of. the mass of an atom is concentrated in the nucleus?

(A) most of the mass of the atom is concentrated in its nucleus. (R) all alpha particles striking a gold sheet are scattered in different directions.

Most of the mass of an atom is located

Give the scientific reason : All the mass of an atom is concentrated in the nucleus.

In the HCI molecule the separation between the nuclei of the two atoms is about 1.27xx10^(-10) m. Find the approximate location of the Centre of mass of the molecule. Given that a chlorine atom is about 35.5 times as massive as a hydrogen atom and nearly all the mass of an atom is concentrated in its nucleus.

In the HCl molecule, the Separation between the nuclei of the two atoms is about 1.27 A (1A =10^(-10)m) Find the approximate location of the centre of mass ofthe molecule Given : chlorine atom is about 35.5 times as massive as a hydrogen atom and nearly all the mass of an atom is concentrated in its nucleus
