What principal quantum number?

The principal quantum number is the level of the most energetic electrons in an atom. It also corresponds to which period the element is in on the periodic table. For example, barium has a principal quantum number of 6 because its valence electrons are in level 6, and the element is in period 6.

What is the number of electrons can an orbit contain?

If you mean orbital then only 2 electrons of opposite spin. If you mean a principal energy shell then the the number is 2n2 where n is the principal quantum number.


How is an orbital's principal quantum number related to the atom's major energy levels?

The principal quantum number describes the size of the orbital. Because they have opposite electrical charges, electrons MORE.


How many valence electrons does a carbon atom have?

Carbon has four valence electrons. Each of theseelectrons can pair with an electron from another atom to form a strong covalent bond. In carbon, all the electrons with the principal quantum number 2 are valence electrons, but the two electrons with principal quantum number 1 are not.

2 electrons


What is the principal quantum number for the outermost electrons in a bromine atom in the ground state?

The electronic configuration of Bromine in its ground state is: 1s2 2s2p6 3s2p6d10 4s2p5. Therefore the principal quantum number for the outermost electrons in a Bromine atom is 4.


How many electrons are in the innermost shell of an atom?

The innermost shell of an atom is the shell corresponding to the principal quantum number of 1. Because the principal quantum number is 1, the angular quantum number and the magnetic quantum number of that shell must be 0. Therefore, only 2 electrons can possibly be in the innermost shell, one with spin up and the other with spin down.

The principal quantum number - n- describes the energy level. An example would be electrons at 2p^6 are at the energy level represented by n=z


How do you know how many electrons need to go in the second shell?

The formula is 2n2 where n is the principal quantum number (the "shell" number). In this case the second shell has a principal quantum number of 2 so 2X 22 = 8

2. Iron configuratoiin is [Ar] 3d84s2


What is the principal quantum number of sulfur?

It goes by valence electrons. The configuration of Sulfur is: 1s2 2s2 2p6 3s2 3p4. Sulfur has 6 valence the electrons in the 3s and 3p oribitals. So the principal quantum number, which is denoted by n, is equal to 3. Thus n=3 is for sulfur.


Which quantum number is also called sub-shell quantum number?

This is the principal quantum number, n.


What is the total number of electrons in an atom's fourth principal energy level?

The atomic states with principal quantum number 4 can have orbital angular momentum quantum numbers from -4 to 4. Hence there are 9 possible values of the orbital angular momentum quantum number. Each electron can have spin +1/2 or -1/2, so each of the states specified by a given orbital angular momentum quantum number can have at most two electrons in the state without violating Pauli's exclusion principle. So, in sum, there are 18 possible states for an electron with principal quantum number 4.
