Want this question answered?
By the first principle energy level I assume you are referring to the lowest atomic orbital or ta principal quantum number of 1. This orbital holds 1 pair of 2 electrons.
The principal energy level is three, so there are three sublevels: 3s, 3p, and 3d. S,P and D
2
how would i know it is 2
Depends on what one means by "smaller". Since sublevels are "inside" or part of the principle energy level, then yes, they are smaller.
There are 2 energy sublevels in the second principal.
The quantum number for that energy level.
There are two sublevels in the 2nd principal energy level. They are the 2s and 2p sublevels.
The 2s and 2p sublevels in the second principal energy level are completely occupied in the ground state of a sodium atom.
the orbitals of the sublevels of the same principal energy level differ in shape which describes where the electron is likely to be found. Also the orbitals of sublevels have different energy levels. In ascending enegy in any level s < p < d < f < g etc HOWEVER whether the different sublevels exist depends on the principal energy level ie 1s 2s, 2p 3s, 3p, 3d 4s, 4p, 4d, 4f
There are five sublevels in the fifth energy level: 5s, 5p, 5d, 5f, and 5g.
By the first principle energy level I assume you are referring to the lowest atomic orbital or ta principal quantum number of 1. This orbital holds 1 pair of 2 electrons.
Zinc atoms contain 30 electrons in the electron configuration 1s22s22p63s23p63d104s2. There are a total of 7 sublevels that contain electrons in an atom of zinc in the ground state.
Principal energy levels are an atom's major energy levels, ranging in value from 1 to 7. Energy sublevels are contained within principal energy levels, and their number increases as the value of the principal energy level increases.
1st energy has 1 sublevel -- 1 orbital -- 2 electrons 2nd energy level has 2 sublevels -- 4 orbitals -- 8 e- 3rd energy level has 3 sublevels -- 9 orbitals -- 18 e- 4th energy level has 4 sublevels -- 16 orbitals -- 32 e- Notice the pattern? number of orbitals = energy level squared Number of electrons = 2x number of orbitals
The answar is: magnetic quantum number
The orbital will be described with a number, followed by a letter, which may have a suffix. The number is the principal energy level. For example 2p, principal energy level 2; 5d principal energy level 5; 1s principal energy level 1.
