The group that needs one more electron to fill its outer energy level?
Halogens
How many electrons are on uraniums outer energy level?
Two electrons
How many electrons are in the outer energy level of xenon?
8 electrons
Is valence electrons in the outer most orbital?
No. Valence electrons are the electrons in the outer most orbit (or energy level) and not in outer most orbital.
How many electrons in halogens outer shell?
There are 7 electrons! Hehe
How many electrons are in the outer electron level of the halogen?
7 electrons are on the outer (valence) shells of all halogens
What group of elements with seven electrons in the outer level?
halogens (group 17 elements)
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.

Why halogens are coloured?
halogens are coloured due to absorption of radiation in visible rangewhich results in the excitation of outer electrons to higher energy level. hence,HALOGEN show colour

Two electrons
The electrons in the outer energy level of an atom are called?
The are the valence electrons.
How many electrons are in the outer energy level of xenon?
8 electrons
Which family of elements has 7 valence electrons in their outer energy level.?
Elements with 7 electrons in their outermost energy levels are most likely halogens. This is group 17 (or 7A) on the periodic table, and they include the common and highly reactive elements fluorine (F), chlorine (Cl), bromine (Br), and iodine (I).
