there are 8 electrons in the valence shell of neon
there are 8 electrons in the valence shell of neon
Period number = no. of electron shells. Therefore neon has two shells.
Neon has 8 valence electrons. Each electron shell can hold a maximum of 8 electrons, so the valence electrons are the electrons in the outermost shell. Neon is in the 8th column of the periodic table, so it has a full outer shell.
If the valence orbital of an atom is full, the atom is stable and less likely to interact with other atoms to form chemical bonds. This is because a full valence orbital fulfills the octet rule, meaning the atom has attained a more stable electron configuration.
It has 8 valence electrons.
Valence electrons can determine the reactivity of the atom. An atom with a full shell of valence electrons, like neon, will be less reactive than an atom with only one electron in its valence shell, like sodium.
Both a neon atom and a sodium ion have 10 electrons. Neon is a noble gas with a full valence shell, while a sodium ion has lost one electron to achieve a stable electron configuration.
This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
Magnesium will lose 2 electrons to have the same electron configuration as Neon. Neon has a full valence shell with 8 electrons, and Magnesium has 2 valence electrons. By losing 2 electrons, Magnesium can achieve a full valence shell and the same electron configuration as Neon.

10
Neon is in group 8 of the periodic table, so it has 8 valence electrons.
When aluminum (Al, #13) reacts, it loses its three valence electrons to achieve the same electron configuration as neon (Ne, #10.) That configuration is 1s22s22p6. So yes, Al+3 has the same configuration as neon.
