eight
An aluminum atom has three valence electrons and needs to give up all three to achieve a stable electron configuration similar to that of a neon atom, which has a full octet of eight valence electrons. By losing these three electrons, aluminum attains a stable, positively charged ion (Al³⁺), resembling the noble gas configuration of neon.
there are 8 electrons in the valence shell of neon
Period number = no. of electron shells. Therefore neon has two shells.
there are 8 electrons in the valence shell of neon
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.
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.
An aluminum atom has three valence electrons and needs to give up all three to achieve a stable electron configuration similar to that of a neon atom, which has a full octet of eight valence electrons. By losing these three electrons, aluminum attains a stable, positively charged ion (Al³⁺), resembling the noble gas configuration of neon.
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.
Period number = no. of electron shells. Therefore neon has two shells.
