A helium he atom has 2 electrons that are both in the outermost energy level how many more electrons does the atom need to fill its outermost energy level?
It is the most stable element in the universe and does not need anymore electrons. Its outermost energy level is full.
How many valence electrons does helium need to have filled outermost energy level?
helium has 2 valence electrons (in s orbital) and has complete s orbital. So it does not need to gain or lose more electrons to be stable.
How many valence electrones does helium need to have a filled outermost energy level?
helium has 2 valence electrons (in s orbital) and has complete s orbital. So it does not need to gain or lose more electrons to be stable.
How many electrons of the most stable have in there outer energy level?
The most stable atoms/ions have 8 electrons in their outermost shell.
Why do atoms join to other atoms?
To become stable. When the outermost energy field is filled to maximum electrons, the atom is stable.
An atom is stable when its outermost orbit is?
It is stable when filled with electrons.
How many valence electrons do stable atoms have?
A stable atom has 8 electrons in its outer most valence shell. A simple way to remember this is that all atoms want to be like the noble gases which all have 8 electrons (except helium but the reason is complicated and not necessary here)
How the number of electrons in an energy level affect bond formation?
If the atom is chemically stable it doesnt need to bond, it is chemically stable when the outermost level is completely full of electrons
Valence electrons of helium?
Helium has two valence electrons in the 1s orbital.
Do noble gases have the maximum number of electrons in their outer energy level?
Yes, the outermost energy level of the atoms of the noble gases are filled, meaning that they have the maximum number of electrons. This is why noble gases are stable and unreactive. The atoms of reactive elements share or transfer electrons in order to fill their outermost energy levels, making them stable like the noble gases.
An atom that contains 8 electrons in its outermost energy level is said to be?
Those with a stable octet are referred to as noble gases. They are highly stable elements. For eg:- Helium, Neon and Argon. A few compounds of Xenon and Argon have been formed, but these are referred as Noble gases.
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.
