Do group 7 electrons have 7 electrons in the outer shell?
Group seven elements have 7 electrons in their outermost energy level.
How many electrons are in the highest occupied energy level in Group 8A?
8 electrons
What is the number of electrons in the highest occupied energy level of an element in Group 15?
5 valence electrons.
What is an element whose atoms contain 4 electrons in the second energy level?
Carbon. Carbon is in the second period, so it has electrons in its second energy level, and it is in the fourth group in the second energy level, so it has 4 electrons.
How many electrons are in the highest occupied energy level of oxygen?
Oxygen atoms have 6 electrons in the highest occupied energy level. They are two 2s electrons and four 2p electrons. All elements in Group 16 have 6 valence electrons. For Groups 13-18, subtract 10 from the group number and that gives you the number of valence electrons (the electrons in the highest energy s and p orbitals). The Group 1 elements have one valence electron and the Group 2 elements have two valence electrons. The transition metals can vary in the number of valence electrons. You can't necessarily go by group number for them.
Do group 7 electrons have 7 electrons in the outer shell?
Group seven elements have 7 electrons in their outermost energy level.
How many electrons are in the highest occupied energy level in Group 8A?
8 electrons
How many electrons are in the highest occupied energy level atom barium?
2. the number of electrons on the outermost level is always equal to the group number. Barium is group 2 therefore it's outermost energy level contains 2 electrons
What is the group that has four electrons in the fourth energy level?
group 2 (or the second column)
What is the number of electrons in the highest occupied energy level of an element in Group 15?
5 valence electrons.
What is an element whose atoms contain 4 electrons in the second energy level?
Carbon. Carbon is in the second period, so it has electrons in its second energy level, and it is in the fourth group in the second energy level, so it has 4 electrons.

Which group has a complete set of valence electrons in their outer energy level?
noble gases
How many electrons are in the outermost energy level of arsenic?
Five, Arsenic is in group 15
Which group has a complete set of valence electrons in their outermost energy level?
The noble gasses.
What group of elements has a staple number of electrons in their outer energy level?
Group 18 elements have a stable octet.
How many electrons are in the outermost energy level of carbon and how many does it need to have this energy level filled?
Carbon has four electrons in the outermost energy level, which is energy level two. It needs eight electrons to have this energy level filled.
