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.
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.
yes.they have the maximum number of electrons in their outer energy level?
The halogen that will have its outer energy level filled with 2 electrons is astatine (At). Halogens typically have seven valence electrons, but astatine is a heavier element that can form stable compounds where it can exhibit a +1 oxidation state, effectively allowing it to achieve a filled outer shell in certain contexts. However, it's important to note that in its elemental form, astatine, like other halogens, primarily exists with seven valence electrons.
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.
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.
