How many number of electrons of helium in outer ring?
Helium has only two electrons with one ring (or energy level). Both the electrons are in the one and only energy level / shell / ring.
Do all noble gases except helium have 18 electrons in their outer energy level?
Yes, all noble gases except helium have 18 electrons in their outer energy level, which corresponds to a full valence shell. Helium has only 2 electrons in its outer shell, which is the maximum for its first energy level. The other noble gases, such as neon, argon, krypton, xenon, and radon, have 8 electrons in their outer shell, making them chemically inert and stable. The electron configuration of these elements contributes to their lack of reactivity.
How many electrons do the noble gases have in there outer energy levels?
8, with the exception of helium which has 2.
How many electrons are found in the outer lever of all the noble gases except helium?
There are 8 electrons in the outer level of all the noble gases except helium. This full outer level gives them stability and makes them less reactive. Helium, as a noble gas, has only 2 electrons in its outer level.
Which element has a full outer most energy level containing only two elecreons?
Elements that have full outer most energy levels containing 2 electrons would be those in group 2 of the periodic table (alkaline earths). Namely, Be, Mg, Ca, Sr, Ba, and Ra. Helium also has 2 electrons in it's outer most energy level.
What two atoms will have their outer energy level filled with two 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.
Does an atom of helium have eight electrons in its outer energy level?
the largest number of electrons an atom of helium can have is 2, because it is in the first period, which means it can only have one energy level, which has a maximum capacity of two electrons
Which atom does not need 8 electrons in it outer energy level to be stable?
Hydrogen is an atom that does not need 8 electrons in its outer energy level to be stable. Hydrogen only needs 2 electrons to fill its outer energy level.
How many number of electrons of helium in outer ring?
Helium has only two electrons with one ring (or energy level). Both the electrons are in the one and only energy level / shell / ring.
Which group has a stable number of electrons in their outer most energy level?
All the noble gases Helium, Neon, Argon, Krypton, Xenon and Radon have a stable octet of electrons in their outer energy level.
Is a noble gas such as helium tends not to form compounds with other elements its outer energy level is missing two electrons?
Correct, noble gases such as helium have full outer energy levels and are stable, making them unlikely to form compounds with other elements. In the case of helium, it has only two electrons in its outer energy level, fulfilling the octet rule without the need to gain or lose electrons.
Do all noble gases except helium have 18 electrons in their outer energy level?
Yes, all noble gases except helium have 18 electrons in their outer energy level, which corresponds to a full valence shell. Helium has only 2 electrons in its outer shell, which is the maximum for its first energy level. The other noble gases, such as neon, argon, krypton, xenon, and radon, have 8 electrons in their outer shell, making them chemically inert and stable. The electron configuration of these elements contributes to their lack of reactivity.
What element with 1-2 electrons in the outer energy level?
Hydrogen, helium, alkali, alkaline metals.
How many electrons do the noble gases have in there outer energy levels?
8, with the exception of helium which has 2.
How many electrons are on uraniums outer energy level?
Uranium has 2 electrons on its outer energy level.
What element that is considered unreactive because it has a filled outer energy level is?
Helium is considered unreactive because it has a filled outer energy level with two electrons in its 1s orbital. This makes it very stable and unlikely to form chemical bonds with other elements.
How many electrons nitrogen has in its outer energy level and how many does bromine have?
Nitrogen has 5 electrons in its outer shell, and Bromine has 7 electrons in its outer shell.
