### Hybridization of Central Atom

Can someone explain to me how to know if the hybridization of an atom is either in 1s or 2s? For example in number 2.45 in the 7th edition, the book asks to Identify the composition of the bonds and the hybridization of each lone pair—for example, by writing s (H1s,C2sp 2). How do you know that the carbons are in the second orbital (2sp^2) rather than just sp^2?

I think it is because carbon is on the second row of the periodic table, making it 2.

This is simply due to the period number of Carbon.

Just to reiterate what has been said previously, the 2 (coefficient in front of sp) in 2sp^2 is basically like the n quantum number that states the energy level such as in 2s or 2p.

2sp shows that the s and p orbitals from n=2 have been hybridized.
