How many electrons are possible in K and L shell?

Therefore, the K shell, which contains only an s subshell, can hold up to 2 electrons; the L shell, which contains an s and a p, can hold up to 2 + 6 = 8 electrons, and so forth; in general, the nth shell can hold up to 2n2 electrons.

Which one of the following element has 2 electrons in the K shell only?

Since the electrons in atoms are filled in the lower orbits first and then in higher energy orbits, all the atoms except for hydrogen will have two electrons in its ‘K’ shell as they will have more than two electrons (K shell cannot contain more than two electrons according to 2n2 rule) .

Why does L and M shell have 8 electrons?

The maximum capacity of a shell to hold electrons is 8. The shells of an atom cannot accommodate more than 8 electrons, even if it has a capacity to accommodate more electrons. This is a very important rule called the Octet rule.

What is K and L shell?

K,L,M,N shells K denotes the first shell (or energy level), L the second shell, M, the third shell, etc. Therefore, electrons will first fill the K shell, then the L shell, the M shell, the N shell, etc.

Which ions have same electron configuration?

Answer: Fe3+ and Mn2+ Fe3+ and Mn2+ will have the same electron number, that is 23, and will therefore have the same electronic configuration.

How many electrons are present in the M shell of an atom of the element with atomic number Z 24?

the electronic configuration of the element with atomic number 24 is, 2, 8 , 8 ,6. thus , 8 electrons are present in the M shell of the 24th element.

How many electron are there in M shell?

eight electrons
The M shell only holds eight electrons. The M shell can actually hold up to 18 electrons as you move to higher atomic numbers.

What is K shell in chemistry?

Definition of K-shell : the innermost shell of electrons surrounding an atomic nucleus and constituting the lowest available energy level for the electrons — compare l-shell , m-shell.
