1) what are the two main parts of an atom is made of ?
2) where is the nucleus of an atom situated ?
3) what are orbits or shells of an atom ?
Answers
Answer:
1.An atom is composed of two regions: the nucleus, which is in the center of the atom and contains protons and neutrons, and the outer region of the atom, which holds its electrons in orbit around the nucleus.
2.I don't know
3.The circular orbits (shell present ) in the space available around the nucleus on which electrons revolve are called orbits or shells of an atom.
Answer:
1. atom is made up of positive and negatively charged particles namely protons and electrons.(neutrons are also present they are neutral)
2.it is situated at the centre of the atom.
3.The orbits are imaginary path in which the electrons are located in 2n^2 rule. orbits are energy levels of the shell which denote the energy of electrons. Exceptional case is at first orbit only two electrons are present and at the last orbit only 8 electrons are present.
Explanation:
in first shell only two electrons are present due to small path the electrons get repelled and in last it has to be eight electrons.
