Cesium has one electron in its outer ring. It belongs to group 1 of the Periodic Table, which means it has one valence electron.
There are 7 electrons in the outer "ring" of bromine.
Magnesium has 2 electrons on its outer energy level.
8 all together
Sodium has one outer ring electron, and chlorine has seven outer ring electrons. Sodium tends to lose its outer electron, while chlorine tends to gain an extra electron to achieve a stable electron configuration.
A full outer ring of an atom is when it has achieved the stable electron configuration known as the octet rule, where the outermost energy level is filled with 8 electrons (2 electrons for hydrogen and helium). This makes the atom more stable and less reactive.
Calcium has 2 outer ring electrons, while oxygen has 6 outer ring electrons.

The outer ring of electrons, or the valence electrons.
Sodium has one outer ring electron, and chlorine has seven outer ring electrons. Sodium tends to lose its outer electron, while chlorine tends to gain an extra electron to achieve a stable electron configuration.
Flerovium is element 114 on the periodic table, and its electron configuration is [Rn] 5f14 6d10 7s2 7p2. This means that the outermost electrons, in the 7s and 7p subshells, add up to 4 electrons in the outermost ring.
A sodium atom has one outer ring electron. Sodium belongs to Group 1 of the periodic table, so it has one electron in its outermost electron shell.
Oxygen has 2 electron rings. The first electron ring can hold up to 2 electrons, and the second electron ring can hold up to 6 electrons. Oxygen typically has 8 electrons, with 6 in the outer ring.
Helium has 2 electrons total, and both of these electrons are in the first energy level with only 1 sublevel (s-sublevel). Therefore, both electrons in helium are in the outermost ring.
A full outer ring of an atom is when it has achieved the stable electron configuration known as the octet rule, where the outermost energy level is filled with 8 electrons (2 electrons for hydrogen and helium). This makes the atom more stable and less reactive.
