Do all nonmetals have a completelyfull Valence shell of electrons?
There is no set amount of valence electrons for nonmetals. The amount of valence electrons a nonmetal has is determined by the number of electrons on the outer shell of the atom.
What is the the symbol for one element that DOES NOT need eight electrons to have full set of valence electrons?
He
How many valence electrons do the boron group have?
Boron is located in group 3A. It is group 13 in modern notation. This set of elements have three valence electrons.Boron is in the 13th group in the periodic table. Elements in this group has 3 electrons in the outermost energy level. That means they have 3 valence electrons.
What ion will be formed by a selenium atom when it has a stable set of valence electrons?
Se2-Se 2-
What have a full set of electrons on their outermost energy level?
The noble gases (group 18/VIIIA/0) are naturally occurring elements that have a full valence shell with eight valence electrons (an octet), except for helium which has two valence electrons (a duet). This makes these elements very stable and very nonreactive.
How will atoms with 5 valence electrons achieve a full set of valence electrons?
They will gain 3 electrons from something with 3 valence electrons.
How with 4 valence electron will achieve a full set of valence electron?
An atom with 4 valence electrons will have to either gain 4 electrons or lose 4 electrons to achieve a full set of eight electrons.
Do all nonmetals have a completelyfull Valence shell of electrons?
There is no set amount of valence electrons for nonmetals. The amount of valence electrons a nonmetal has is determined by the number of electrons on the outer shell of the atom.
Can helium have a full set of valence electrons?
It does.
What states that atoms tend to gain lose or share electrons in order to achieve a full set of valence electrons typically?
The octet rule.
How can an atom that has 5 valence electrons achieve a full set of valence electrons?
Either lose 5 electrons, which is least likely, or gain 3 electrons.
How many electrons make up a full set of valence electrons?
8
What is the the symbol for one element that DOES NOT need eight electrons to have full set of valence electrons?
He
Why are the valence electrons located in an atom?
If you mean "where are the valence electrons" then they are flying around the outside of the atom.If you mean "why" then I don't know. they're just there to be the outermost set of electrons.
How with 5 valence electrons will achieve a full set of valence electrons?
If you're asking how will an atom with 5 valence electrons will achieve a full set of valence electrons, then the answer would be that they bond with other atoms to gain a full set of the valence electrons by sharing or gaining 3 electrons.
How many valence electrons do the boron group have?
Boron is located in group 3A. It is group 13 in modern notation. This set of elements have three valence electrons.Boron is in the 13th group in the periodic table. Elements in this group has 3 electrons in the outermost energy level. That means they have 3 valence electrons.
What is the symbol for one element that DOES NOT need eight electrons to have full set of valence electrons?
The element is helium, with symbol He.
