s ORBITALS
An s orbital is spherically symmetric around the nucleus of the atom, like a hollow ball made of rather fluffy material with the nucleus at its centre. As the energy levels increase, the electrons are located further from the nucleus, so the orbitals get bigger. The order of size is 1s < 2s < 3s < …, as shown below.
Now, let’s look at a cross-section of these orbitals.
If you look carefully, you will notice that a 1s orbital has very little electron density near the nucleus, but it builds up to a maximum as you get further from the nucleus and then decreases beyond the contour. It is sort of like a hollow tennis ball.
A 2s orbital is similar to a 1s orbital, but it has sphere of electron density inside the outer sphere, like one tennis ball inside another. There is a surface between the two balls where there is zero probability of finding an electron. We call this surface a node or a nodal surface.
A 3s orbital is even larger, and it has three nodes.

every atom has orbits and that orbits has orbitals the first orbital is called as s and it can acomodate maximum 2 electrons
