Group 17 elements have 7 electrons in the outermost energy level.They are less reactive and belong to halogen group.For example electronic configuration of Fluorine is 2,7.

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.


Elements in a group have-?

Elements in group have same number of valence electrons. They also have same chemical properties.


What is the number of valence electrons for group 2 elements?

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).


Where are elements with the same number of valence electrons?

All elements in the same group have the same number of valence electrons.


What is the different about the valence electrons for all elements in a group?

The valence electrons for elements in the same group stay the same, since the number of valence electrons corresponds to the group number.


How are the electron clouds of the atoms of the elements in a group the same?

Atoms of the elements in a group have the same number of electrons in their outer energy shells. This gives the elements similar Chemical Propetries.

Elements in a group or family have similar properties?

Because groups/families determine how many valence electrons the element will have. Therefore, all the elements in a group/family have the same number of valence electrons Chemimal and Physical.
