The lowest energy level of 4th electronic shell of an atom is '4s' it contains 2 electrons in maximum.
The orbit is the bone encasement that holds the eyeball.
an f orbital
The d orbital is the orbital that only applies to the 3rd orbital and up and it contains 10 electrons.
The 2s orbital and 3s orbital both have the same spherical shape and can hold a maximum of two electrons of opposite spin. They only differ because the 3s orbital is further out from the nucleus than the 2s orbital, thus the 3s orbital has a higher energy value.
4f orbital
The orbital is in the eye socket.
The 2s orbital is larger than the 1s orbital and is higher in energy.
Yes dsp2 is an inner orbital complex. It involves the inner d orbital.
vacant d orbital means an empty d orbital. For example, in nitrogen a d orbital is not allowed whereas in phosphorus a vacant d orbital is present.
If inner d orbital is involved in hybridization, it is called inner d orbital complex. and if outer d orbital is involved in hybridization then it is called 'outer d orbital complex'.
s-orbital
The s orbital fills before the p orbital because it has lower energy, and is more stable.
the 2s orbital is at a higher energy level
