Atomic Structure and Chemical Bonding – Notes
Structure of Atoms – Structure of an Atom
An atomic number is the number of protons in an atom.
The arrangement of electrons in various energy levels of an atom is known as electronic configuration.
The maximum number of electrons in any energy level of the atom is given by 2n2.
The outermost shell in an atom is cannot more than 8 electrons.
Combining capacity of the atom to form molecules either with the same or different elements is known as valency.
Neutrons are a neutral particle present in the nucleus.
The total number of protons and neutrons present in one atoms of an element is referred as atomic mass
