What is the the symbol for one element that DOES NOT need eight electrons to have full set of valence electrons?
He
How many valance electrons in neon?
Eight - it has a full outer shell of electrons.
Which group elements do not bond easily?
The noble gases, in column 18 (or in older tables, column VIII) do not bond, they already have full set of electrons. the rest all bond because they want full set of electrons to be more stable.
The second energy level contains how many electrons when it is full?
The second energy level contains eight valance electrons when it's full.
How many electrons does each atom desire?
Atoms do not actually have desires as such, although the metaphor can be useful. Atoms are more stable when they have a full outer electron shell. The smaller atoms, hydrogen, helium, lithium, and beryllium, can obtain a full outer shell with only two electrons in it. The heavier atoms require 8 electrons to have a full outer shell. That is known as the octet rule (an octet is a set of eight).
How many electrons make up a full set of valence electrons?
8
Are two electrons a full set?
no
Can argon have a full set of electrons?
Yes, it can.
Can helium have a full set of valence electrons?
It does.
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.
Does neon have a full set of electrons?
Yes, it is true.
What is the the symbol for one element that DOES NOT need eight electrons to have full set of valence electrons?
He
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 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.
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.
How many full electrons does krypton have?
Krypton has 8 valence electrons.
How many valance electrons in neon?
Eight - it has a full outer shell of electrons.
