Stable.
Fluorine needs 8 valence electrons to have a filled outer energy level, following the octet rule. Fluorine naturally has 7 valence electrons, so it only requires one more electron to achieve a stable octet configuration.
yes.they have the maximum number of electrons in their outer energy level?
filled. That would be 2 electrons for helium, and 8 electrons for the rest of the noble gases in group 18 on the periodic table.
The valence shell (outermost energy level) of a noble gas is filled in ... ns2 np6 electron configuration except helium where it is 1s2.
If the outer energy level of an atom is already filled with electrons, it is less likely to react because atoms tend to be more stable when their outer energy levels are full. This full outer level signifies that the atom has achieved a more stable electron configuration (usually the octet rule for most elements).
Helium and neon will have their outer energy level filled with two electrons. Helium has 2 electrons in its only energy level, while neon has 8 electrons in its second energy level.
it is called complete or completely stable
Uranium has 2 electrons on its outer energy level.
Nitrogen has 5 electrons in its outer shell, and Bromine has 7 electrons in its outer shell.
A noble gas is considered unreactive because it has a filled outer energy level. The full outer energy level provides stability and low reactivity, as the element does not need to gain or lose electrons to achieve a stable electron configuration.
Helium (He) and Neon (Ne) will both have their outer energy level filled with 2 electrons.
Vanadium has 5 electrons in its outer energy level.
Fluorine needs 8 valence electrons to have a filled outer energy level, following the octet rule. Fluorine naturally has 7 valence electrons, so it only requires one more electron to achieve a stable octet configuration.
Iodine has 7 electrons in its outer energy level.
There are 8 electrons in the outer energy level of xenon. Xenon belongs to the noble gas group on the periodic table, which have a full outer energy level with 8 electrons.
Sulfur has 6 electrons in its outer energy level. This means it needs 2 more electrons to fill its outer energy level, for a total of 8 electrons.
