It depends which n since n is the row (period) number. 1st n = 1-s subshell, 1 orbital, and 2 electrons. 2nd n = 2-s subshell with 1 orbital and 2 electrons + 2-p subshell with 3 orbitals and 6 electrons.

How many energy sublevels are there in the second principal level?

In the second principal energy level, there are two types of sublevels: the s sublevel and the p sublevel. The s sublevel can contain a maximum of 2 electrons, while the p sublevel can hold up to 6 electrons.


How many electrons are present in the third principal quantum number of an atom?

In the third principal quantum number (n=3), there are a maximum of 18 electrons that can be accommodated in different sublevels within that energy level (s, p, d).


How many energy sublevels are in the second principle energy level?

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.


How are principle energy levels and energy sub levels related?

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.


How many sublevels are completely occupied in the second principal energy level of a sodium atom in the ground state?

In the ground state, a sodium atom in the second principal energy level has two sublevels completely occupied: the 2s and the 2p sublevels. The 2s sublevel can hold a maximum of 2 electrons, and the 2p sublevel can hold a maximum of 6 electrons.


How many energy sublevels are in second energy level?

There are two energy sublevels in the second energy level - the s sublevel and the p sublevel. The s sublevel can hold a maximum of 2 electrons, while the p sublevel can hold a maximum of 6 electrons.


What is the total number of occupied sublevels in the third principal energy level of a zinc atom in the ground state?

The third principal energy level (n=3) has s, p, and d sublevels. In the ground state, the zinc atom has all the s, p, and d sublevels in the n=3 energy level occupied. Therefore, the total number of occupied sublevels in the third principal energy level of a zinc atom in the ground state is 3.


Which sublevel will contain electrons with the greatest energy?

Electrons with the greatest energy are found in the outermost sublevels, typically in the s or p sublevels of an atom. These sublevels are farther from the nucleus and have higher energy levels than the inner sublevels.


How many Energy sublevel are in the second principle energy level?

There are two sublevels in the second principal energy level: the s sublevel and the p sublevel. The s sublevel can hold a maximum of 2 electrons, while the p sublevel can hold a maximum of 6 electrons.


What does the periodic table have seven of?

valence electrons and energy sublevels


The number of sublevels in an energy level is equal to the square of the principal quantum number of that energy level?

No, the number of sublevels in an energy level is equal to the principal quantum number itself, not its square. The principal quantum number represents the main energy level or shell an electron occupies, while the sublevels (s, p, d, f) represent different orbital shapes within that energy level.


How are the orbital different in sublevels of the same principal energy level?

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
