1st shell: 2 electrons, 2nd shell: 8 electrons, 3rd shell: 8 electrons, 4th shell: 4 electrons, 5th shell: 0 electrons, 6th shell: 0 electrons.
In a group, elements have the same number of outer shell electrons, which corresponds to the group number. For example, elements in Group 1 have 1 outer shell electron, elements in Group 2 have 2 outer shell electrons, and so on. This pattern helps determine the reactivity and chemical properties of elements within the same group.
Shell 1: Two electrons Shell 2: Eight electrons Shell 3: Eight electrons Shell 4: Eighteen electrons
Phosphorous has 2 elements in K-shell, 8 in L-shell and 5 in M-shell.
This element is sulfur (S), with 2 electrons in the first shell, 8 electrons in the second shell, and 6 electrons in the third shell.

2 electrons in the K shell and 8 electrons in the L shell
In the first shell there are two electrons and in the second shell there are six electrons, but only the electrons in the second (outer) shell are valence electrons.
Maximum number of electrons = 2n2, where n is the number of shell (n = 1 for K, 2 for L, 3 for M, and so on) K shell has 2 electrons maximum L shell has 8 electrons maximum M shell has 18 electrons maximum N shell has 32 electrons maximum O shell has 50 electrons maximum P shell has 72 electrons maximum
Valence electrons are the electrons in the outermost shell of an atom. The ones in the inner shell are known as core electrons.
Phosphorous has 2 elements in K-shell, 8 in L-shell and 5 in M-shell.
This element is sulfur (S), with 2 electrons in the first shell, 8 electrons in the second shell, and 6 electrons in the third shell.
First Shell always has 2 electrons. Second shell onwards can have up to a maximum of 8 electrons.
It has 5 electrons in its outermost shell.
