Ans 1) What does an atom looks like? What are the sub-atomic particles inside it... (talk about electrons, neutrons, protons, electron shells, nucleus...)
The atom is the smallest foundation unit or particle of an element that can exist. The sub-atomic particles are the Protons, Neutrons and Electrons.
The protons and neutrons are found in the nucleus of the atom. Electrons are found on the electron shells.
Protons, the number of protons in the nucleus of an atom is called the proton number or atomic number. Elements in the Periodic Table are arranges in order of their proton numbers.
Proton and Neutron both have a relative mass of 1, whereas Electron has a relative mass of 1/1840. Proton '+', Electron '-'
Proton have a relative charge of +1, Neutron 0, Electron -1. The first shell can hold up to 2 shells, second shell 8, third shell 8, forth shell 18.
