An atomic or molecular energy state which cannot accommodate any more particles. The lowest electronic level in any atom is the so-called 1s level. This can take up to 2 electrons (basically the 2 spin states "up" and "down"). Hydrogen only has one electron, so that's no problem. Helium has 2, so that second electron can also go in, OK. But Lithium has 3, so we have to start filling up a new energy state ("2s", then "2p"), because the 1s level is "full".
The second energy level contains eight valance electrons when it's full.
No, they don't.
If the outer energy level is full, the element is said to be non reactive and inert. It is stable in nature.
yes they do
Potassium has 1 electron in its outer energy level. When it forms a bond, it typically donates this electron to another element, leaving it with a full outer energy level.
Outermost energy level is full if there are 8 electrons in the valence shell.
Noble gases are unreactive with the outermost energy level full.
Helium has a full outermost energy level containing only two electrons.
They can either gain, share, or lose electrons to have a full energy level
The second energy level contains eight valance electrons when it's full.
Helium has only 2 electrons and its energy level is full.
Atoms form chemical bonds to achieve a full outermost energy level by sharing, gaining, or losing electrons. Valence electrons are the electrons in the outermost energy level of an atom, and having a full outermost energy level makes the atom more stable. This stability is achieved when there are eight electrons in the outermost energy level, known as the octet rule.
No, they don't.
If the outer energy level is full, the element is said to be non reactive and inert. It is stable in nature.
fluorine
Chlorine-35 has three full shells of electrons. It has two electrons in the first energy level, eight electrons in the second energy level, and seven electrons in the third energy level, making a total of 17 electrons.
Nonmetals almost have a full outer energy level while metals have few electrons in their outer energy level.
