In general, the electronic structure of the valence electrons of halogens is given by: ns2, np5
where n is the period in which the halogen is found.
Since the valence electrons are found in both s and p orbitals which have slightly different energies, the valence electrons of halogens are not in orbitals of the same energy level.
What else can I help you with?
How many electrons are in oxygen's outer level?
The word "valance" is used to describe electrons in the outer-most energy level of an atom. Oxygen has six valance electrons.
What are the similarities between alkali metals and halogens?
What causes these to be so reactive is the amount of electrons in the outer most level. Each level after the first (which has 2 if full) if filled will have 8 electrons. Halogens have less than that causing it to be reactive to other elements. (i don't know how many electrons it has in the outer level) The reason why it is reactive is (depending on how many electrons it has in the outer leve) because it is either trying to gain or lose those extra electrons.

What group of elements with seven electrons in the outer level?
halogens (group 17 elements)
The second energy level contains how many electrons when it is full?
The second energy level contains eight valance electrons when it's full.
Seven electrons in the outermost energy level is characteristic of a?
No. That is characteristic of a nonmetal, specifically the halogens (group 17) on the periodic table.
How many valence electrons does an atom of any halogen have?
A halogen is located in group 17 of the periodic table, so the electron configuration for the valance electron would be ns2np5 (n=energy level). So all halogens have 7 valance electrons.
How many electrons do the halogens have in their outer most energy level?
The halogens have 7 electrons in their outer shell desparate to gain the 1 electron to make a full shell of 8 electrons.
What is the name of the electrons in the outermost level of an atom called?
The electrons in the outermost level are known as the valence electrons.

What is valance electron and free electrol describe with figure?
valence electrons are the remaining electrons after which an atom has attains its octate level
Which property is common to all halogens?
Halogens are all non-metals, they are all very reactive, and they are all colorful.
How many electrons are in the outer electron level of the halogen?
7 electrons are on the outer (valence) shells of all halogens
How many electrons does carbon have in the highest energy level?
The valance energy level contains 4 electrons in carbon.
Which electrons are the valance electrons of the atom?
Valence electrons are the electrons in the outermost energy level of an atom. These are the electrons involved in bonding with other atoms and determining the chemical properties of the element.
