Shell or energy level corresponds to the shell in which the electrons are present.
Shells could refer to the energy levels of the electrons.
electron level or orbital
Open
Most chemistry as it is studied is based on the interactions of the valance shell electrons of two or more atoms.
Electrons in the outermost shell are called valence electrons.
M shell notation: N = 3 contains 3 sub shells s,p and d (3s,3p and 3d) *according to my chemistry book.
Anti-Penultimate shells are the ones to the inner side of penultimate shells or the third from the last.

It could be the element Phosphorus, the p orbitals in an atomic shell, etc.
According to my chemistry book (Chemistry: The Molecular Nature of Matter and Change by Silberberg) seashells including clam shells are primarily composed of Calcium Carbonate.

"Chemistry" is done by the outer valance shell of electrons, NOT by the nucleus.
Anti-Penultimate shells are the ones to the inner side of penultimate shells or the third from the last.
The electron shell is also called the principle energy level in chemistry and atomic physics. The shells starting closest to the nucleus names go from shell 1 or shell K, shell 2 or shell L,shell 3 or shell m, etc. Each shell contains a certain amount of electrons the first shell starts with two and the number increases for each shell.
In chemistry, the octet and duplet rules are part of electronic configuration. The octet rule is when the outermost shell has 8 valence electrons. The duplet rule is when the outermost shell has 2 valence electrons, e.g. Helium and Hydrogen.
Florine have only 2 shells namely 1s and 2s is is inner and 2s is outer shell I there is any question related to chemistry then ask me....
