All of the elements in group 8A have this electron configuration except for He! (So a total of 5 elements)
Halogen family members, or elements in group 17, have 7 valence electrons.

Group 18 elements, also known as noble gases, do not typically form ions because they have a full valence shell of electrons. This makes them very stable and unreactive. Their electron configuration of ns2np6 makes it energetically unfavorable for them to gain or lose electrons.
Elements in the Beryllium family have 2 electrons in their electron dot diagrams.
Group 7A elements have 7 electrons in their valence level, while Group 7B elements have 17 electrons in their valence level. This difference occurs because elements in Group 7A have 7 valence electrons, while elements in Group 7B have 7 valence electrons plus the 10 additional electrons in the d sublevel which contributes to a total of 17 valence electrons.
How many valence electrons do transition elements have?

Clay consists of many different elements, and it is therefore impossible to tell how many electrons it has.
There are 7 valence electrons in elements of group-17. They are called halogens.
