The Modern Theory of Atomic Structure: Atomic number: The number of protons in the nucleus of an atom of that element. –Gives the number of electrons in a neutral element. –Gives the order of elements on the periodic table –If an atom gains or loses a proton it not only changes its...
Concept Introduction Atoms: Atoms consist of tiny particles called protons, neutrons and electrons. Proton and neutrons are present in the nucleus and the electron resides around the nucleus. The protons number will be same as the electrons count in the atom. The...
