Outer shell electrons, also known as valence electrons, are the electrons located in the outermost energy level of an atom. They play a crucial role in determining an element's chemical properties and reactivity. The number of valence electrons can often be inferred from an element's position in the Periodic Table, particularly within the main groups, where elements in the same group typically have the same number of valence electrons. For example, alkali metals in Group 1 have one valence electron, while halogens in Group 17 have seven.

Argon (Ar) has 8 electrons in its outer shell. This is because argon belongs in group 18 of the periodic table, known as the noble gases, which have a full outer shell of 8 electrons.
Niobium has 5 electrons in its outer shell. It belongs to group 5 in the periodic table, which means it has 5 valence electrons.
An atom of antimony has 5 outer shell electrons. Antimony is in group 15 of the periodic table, so it has 5 valence electrons.
Electrons per shell in astatine: 2, 8, 18, 32, 18, 7.

There are 5, it is in group 5 on the periodic table of the elements
Iridium has 2 electrons in its outer shell. It belongs to group 9 in the periodic table, which means it has 9 electrons in its valence shell.
There are 8 electrons in the outer shell of a xenon atom. Xenon is in group 18 of the periodic table, which means it has a full octet of electrons in its outer shell.
Argon has 8 valence electrons (electrons in the outer shell)
If you are talking about the valance electrons any elements in group 5 on the periodic table will have 5 valance electrons.
The element with 6 outer shell electrons is carbon. Carbon has 4 electrons in its outer shell and 2 electrons in the shell before that, totaling 6 outer shell electrons.
They have seven electrons in their outer shell they are in group seven on the periodic table.
Argon (Ar) has 8 electrons in its outer shell. This is because argon belongs in group 18 of the periodic table, known as the noble gases, which have a full outer shell of 8 electrons.
There are 2 electrons in valence shell of calcium. :-)
