Orbital ooh! It is like orbit and orbit is something round ooh! Not round but spherical. Sometime differentiating round and sphere can be like climbing a steep mountain to majority of human kind. Back to business, it will be very crucial to understand what a shell is and the number of shells which are possible in an atom.   Shell is a spherical space around a nucleus (nucleus of an atom consists of protons and neutrons, except for one of the hydrogen isotopes (protium), which has a nucleus consisting of one proton. The nucleus has a positive electric charge, the size of which depends upon the number of protons it contains. The nucleus provides the mass of an atom); it contains extra-nuclear electrons with energy levels of that shell. An atom possesses different shells of increasing radii around its nucleus. The radius of a shell is 100 000 times greater than the radius of the nucleus. Ok now let’s focus on these shells of atom. The first one is; K-shell is the innermost at...
