How many electrons are needed in the outer energy levels for the atom to be stable?

Stability isn't determined by the first energy level. The only atom with less than two is hydrogen. It is a very stable atom...reactive in that it will attach to anything, but it will always be hydrogen. The atoms that readily decay (the radioactive ones) all have full first orbitals.

How many electrons are called are needed in the outer energy level of most atoms for the atom to be stable?
Eight electrons, called an octet, are needed by most atoms in order to be stable.
What is the number of electrons needed for stability in the groups of the periodic table?
They r noble gases which have stable valance shell and grotp no. 18
What happen when electron change energy level?
When electrons change energy levels they usually become more stable. Sometimes when electrons change energy levels they become unstable though.
How many electrons are required in the outer energy level for most elements to be stable?
The noble gases is the most stable group of elements. They have their outer electron energy levels full, but the number of electrons vary according to which noble gas it is. They are group 18 on the periodic table.
An atom is stable when it?
it can be stable by completing their octet & minimizing their energy
How many many electrons are needed in the outer energy levels of most atoms for the atom to be chemically stable?
Generally speaking, it would be 8 electrons, but there are many exceptions.
How many electrons are need in the outer energy levels of most atoms for the atom to be chemically stable?
8 are traditionally needed in the valence shell.

Eight electrons, called an octet, are needed by most atoms in order to be stable.
How many electrons are needed in the outer energy level to make H stable?
Only 1 electron needed to make H stable.
What is the group number for elements that have a stable number of electrons in their energy levels?
They r noble gases which have stable valance shell and grotp no. 18

Which group in the periodic table has a stable number of electrons in their outer energy levels?
noble gases or group 1

Do metals and non metals become more chemically stable when they fill or empty their outermost energy levels?
When they fill their outermost energy levels. Metals will WANT more electrons and Non-Metals will have EXTRA electrons to give. So in a way, Metals will actually fill their outermost energy levels while Non-Metals will empty them; all with the goal of having a FULL valency shell which is stable. This is the basis for ionic bonding.
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.
Why do valence electrons determine the reactivity of an atom?
The valence electrons are the outermost electrons. In an atom, its lower energy levels have been filled and are therefore stable. But, except for the noble gases, the valence energy level is not filled, and therefore not stable. So atoms must undergo chemical reactions in order to fill their valence shells and become stable. They can do this by sharing electrons, transferring electrons, or by forming a sea of electrons shared by all the atoms.
