nothing at all, because the s orbital is a spherosophical orbital, while the principal energy level isn't.
n
The quantum number relating to the size and energy of an orbital
The answer is B
the 2s orbital is at a higher energy level
Electron in s-orbital is closer to nucleus than electron in p-orbital and electron in p-orbital is closer to nucleus than electron in d-orbital and so on. So,more energy is requried to remove electron from s-orbital than electron in p-orbital in spite of both having same principal quantum number. Similarly, p orbital will require more energy than d-orbital. this is called penetrating effect. it decreases in order s>p>d>f>... Note that Orbital should have same "n"
n
The quantum number relating to the size and energy of an orbital
1
The principal quantum number describes the size of the orbital. Because they have opposite electrical charges, electrons MORE.
The answer is B
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.
Its Principal quantum no is 2
The principal energy level is three, so there are three sublevels: 3s, 3p, and 3d. S,P and D
1s orbital 3P, 5d, and 7f in discovered elements
the 2s orbital is at a higher energy level
2. The S sub-shell has one orbital and an orbital can hold a max of 2 electrons.
S sub-shell has only one orbital. So, the 2nd energy level has only one s orbital.
