How many valance electrons in neon?
Eight - it has a full outer shell of electrons.
Does Sodium have a full outer valence shell?
No.
When a valance shell has 7 electrons will it gain or lose an electron?
It will gain an electron so that it can complete a full outer shell of 8 electrons.
Why do you think non metals tend to be good at sharing electrons?
All atoms are more stable when their outer most electron shell (valance shell also refered to as a valance orbital but it is slightly different) is full of electrons. Non metals generally have almost full valance shells and it takes less energy to gain a few electrons to reach the stable full outer shell than to lose many electrons to form a stable full outer shell. Take F as an example - it has 7 electrosn in its outermost shell and this shell can fit 8. It will accept 1 electron more easily than losing 7.
What is unreactive and has a full shell on the periodic table?
A noble gas is usually unreactive and has a filled valance electron shell. They are located in group 18 on the periodic table.
How many atoms in the valence shell of sodium?
There is one electron in sodium's valance shell.
How many more valence electrons does sodium need to have a full?
Sodium would need to gain 7 electrons to fill its valance shell. Instead of doing that, however, sodium will lose the one valence electron it does have, leaving behind the shell below it, which is already full.
What makes a group not reactive on the periodic table?
A full octet, valance shell. A valance shell with eight electrons, such as the Nobel gases have, doe not need to donate or accept electrons into or out of the valance shell to be stable.
How many valance electrons in neon?
Eight - it has a full outer shell of electrons.
How many additional valence electrons does fluorine need to have a full valance shell?
1
Why is Ar a noble gas and not Zn?
Argon has a full valance shell, an octet, while zinc does not.
How many valence electronss are there in Boron?
There are three valance electrons. These are the electrons in the outer shell if it is not full.
Does Sodium have a full outer valence shell?
No.
When a valance shell has 7 electrons will it gain or lose an electron?
It will gain an electron so that it can complete a full outer shell of 8 electrons.
What valance shell does hydrogen belong to?
K shell.
