describe how did the bohr prove that atom must exist , Write a Long.... easy wording for 9 class...... I will give u thanks , mark as brainliest , plzzz hurry up

HENRIK NIELS BOHR WAS A GREAT PHYSICST.
HE FORMLY CONTRIBUTED IN PHYSICAL PHYSICS AND QUANTUM CHEMISTRY OF ATOM.
YOUR ANSWER:-
Bohr modified the Rutherford model by requiring that the electrons move in orbits of fixed size and energy. The energy of an electron depends on the size of the orbit and is lower for smaller orbits. Radiation can occur only when the electron jumps from one orbit to another. The atom will be completely stable in the state with the smallest orbit, since there is no orbit of lower energy into which the electron can jump.
PLEASE DON'T BE CONFUSED BETWEEN THE EXISTENCE OF AN ATOM AND STABILITY OF ATOM.
DETAILED EXPLAINATION FOR YOUR ANSWER:-
BASICS
Atoms are the basic unit of chemistry. They are composed of three basic parts:
Atoms are the basic unit of chemistry. They are composed of three basic parts:1) Neutrons: Neutrons are uncharged particles that are found in the center of the atom (the nucleus). Neutrons give mass (weight) to the atom but do not participate in chemical reactions.
Atoms are the basic unit of chemistry. They are composed of three basic parts:1) Neutrons: Neutrons are uncharged particles that are found in the center of the atom (the nucleus). Neutrons give mass (weight) to the atom but do not participate in chemical reactions.2) Protons: Protons are positively charged particles that are also found in the nucleus. Like neutrons, protons give mass to the atom but do not participate in chemical reactions. The number of protons an atom has is called the atom’s atomic number, and determines the atom’s identity (e.g. carbon atoms have 6 protons, oxygen atoms have 8 protons).

They have essentially no mass but are important in chemical reactions. The first electron shell can hold 2 electrons. For most biologically relevant atoms, additional electron shells (if present) can hold up to eight electrons.

For most biologically relevant atoms, additional electron shells (if present) can hold up to eight electrons.Each atom contains equal numbers of protons and electrons. The number of neutrons may vary within atoms of a particular type. (For example, carbon atoms may have 6, 7, or 8 neutrons). Atoms that vary only in the number of neutrons are called isotopes.
ADVANCED:-
(1) When the outer most shell is full..that is it has 8 electrons or 2 electrons in the case of helium..in such cases as the atom has already recevied its octec it does not react with other atoms.
