Oxygen combines by sharing its six valence electrons filling shell 2 through the share, or by adding electrons to the shell through ionization.
The next element with six valence electrons is sulfur with 16 total electrons, two in shell 1, eight in shell 2, and six in shell 3 which is now the valance shell.
Next we have selenium with 34 electrons, six of them valence and tellurium with 52, six valence. Polonium with atomic number (and electrons) equal 84 has six valence, and livermorium with 116 electrons, likewise.
The group that should have 6 valence electrons is Group VI in the Periodic Table. These include elements like sulfur, selenium, oxygen, and tellurium.

Group VIa (transition metals): Oxygen, Sulfur, Selenium, Tellurium and Polonium.
The nitogen, phophorous group (the fifteenth or V(A) group) has five valence electrons.
The halogens group, number 17
Group VIIA, the halogens.
Carbon family group 14

Metals
halogens or group 17
Group 1 with one valence electrons
One valence electrons
The expected number of valence electrons for a group 3 A element is 5 number of valence electrons.
Francium has only one valence electrons.
The name of the family is the Halogen family.
The group of the element indicates the amount of valence electrons. For example, the alkali metals have one valence electron and is in group one whilst the halogens have seven valence electrons and are in group seven.
The halogens, or group 17
Any element in the halogen group will have seven valence electrons. These elements include fluorine, chlorine, bromine, iodine, and astatine.
halogens or group 17
Group 2 metals have 2 valence electrons. In fact, the number of valence electrons of elements can be deduced from the group number (e.g. group VII elements have 7 valence electrons).
Valence electrons are electrons that are on the outside "shell." In Group (column) 1, there is only one valence electrons for each element. In Group (column) 2, there are two valence electrons. Group 13: 3 valence electrons Group 14: 4 valence electrons Group 15: 5 valence electrons Group 16: 6 valence electrons Group 17: 7 valence electrons Group 18: 8 valence electrons There is no Group 19, so this list is done. For the metals, each element will need to be mapped out utilizing the Bohr Diagram design or something of the like as valence electrons are difficult to define due to the grouping on the periodic table. The most valence electrons that can be in an outer shell is eight. Barium (Ba) is in Group (column) 2, and thus has only two valence electrons.
The group numbers tell the number of valence electrons. Without looking on the group number you can also tell the number of valence electrons by looking at the highest energy level in the electronic configuration.
== == It is three, the valence electrons basically depends on the last number of the group its in; such as, group 14 the valence electrons would be 4. i hope i helped
Krypton has 8 valence electrons.
there are 7 electrons in the outer energy level of group 17 elements
It belongs to the Halogens group b/c, it has a valence electrons of seven. (7)
