Non-metals.
The word "valance" is used to describe electrons in the outer-most energy level of an atom. Oxygen has six valance electrons.
Alkali and alkaline earth metals
That, or they, would be the outer most shell electrons. The one(s) that get shared when elements bond. The one that moves out and up when struck by a photon. The one that makes light when it falls back down (gives up its' energy) to its' original shell. ADD: It is a valence electron.
yes.they have the maximum number of electrons in their outer energy level?
Electrons in the outermost principal energy level are called valence electrons.
Elements whose atoms have the same number of outer electrons have similar properties..
Elements whose atoms have the same number of outer electrons have similar properties..
They are the alkaline metals.
The word "valance" is used to describe electrons in the outer-most energy level of an atom. Oxygen has six valance electrons.
There are different numbers of valence electrons in different elements.
Group 18 elements have a stable octet.
Group seven elements have 7 electrons in their outermost energy level.
Group 8
Alkali and alkaline earth metals
oxygen, sulphur and selenium
That, or they, would be the outer most shell electrons. The one(s) that get shared when elements bond. The one that moves out and up when struck by a photon. The one that makes light when it falls back down (gives up its' energy) to its' original shell. ADD: It is a valence electron.
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.
