What group does group one from the periodic table likes to reacts with?
Group one elements are the most reactive with group 7 elements as it is the easiest way for the elements to complete their outer shell as the group one element gives its extra electron to the group 7 element and then the group 7 element has a full shell too.
Why can helium be placed in group II?
The reason it can be placed in group II is because it has 2 electrons in its outside shell (also its only shell) and the groups represent how many electrons in the elements outside shell, the reason it is normally placed in group 8 or 0 is because the first shell has a maximum of 2 electrons and all elements that have a full outside shell are placed in group 8/0 and can't normally react.
Why Helium will not react with anything because it has a complete outer electron shell?
Normally, when elements react they do so to attain a full outer shell, which is stable. Helium already has a full outer shell and so does need to not react to attain one.
What is the physical properties of group 18 elements?
Are very stable Are gases Have a full outer shell Don't react Hope this helps
What is the least reactive groups on the periodic table?
Noble gases are least reactive because they have a full shell
Are basically nonreactive?
Basically non reactive elements are elements that have a full survalence shell meaning that their last shell of neutrons is full., the last shell has 8 electrons or in case of helium 2. because of their full survalence shell they aren't reactive since they are already stable. Alex A.

What do all elements in group 7 have in common?
All elements in group 7 have the same no. of electrons in their outermost shells... and this no. correspondes to the group no.

The group of elements with a full valence are called?
These elements are Nobel Gases in group 18.
Why does xenon not combine readily with other elements?
Elements have a number of electrons in their outer shell of the atom, all elements want to have a full shell and usually form with other atoms to do so. However, Xenon is a noble gas and already has a full outer shell and so does not combine with other elements unless it is made to do so.
What group in the periodic table of elements that has a full outer shell?
The halogens, column 17.
Why don't elements in group 18 usually form chemical bonds?
group 18 elements are what we call noble gasses. This means that their most outer shell called the valence shell has all 8 electrons. The reason why other elements are reactive is because all elements want to have a full valence shell because it makes them more stable. The noble gasses have a full shell so they are not very reactive.
Why are elements like neon and argon unreactive?
Because they already have a full outer shell of electrons, which is the most stable configuration.
Why can helium be placed in group II?
The reason it can be placed in group II is because it has 2 electrons in its outside shell (also its only shell) and the groups represent how many electrons in the elements outside shell, the reason it is normally placed in group 8 or 0 is because the first shell has a maximum of 2 electrons and all elements that have a full outside shell are placed in group 8/0 and can't normally react.

Normally, when elements react they do so to attain a full outer shell, which is stable. Helium already has a full outer shell and so does need to not react to attain one.
How are the families similar in noble gases?
They are all in the same Group VIII. Thus they all have the same # of electrons in their outer shell; which is full. Since the outer shell (valence shell) is full, they are all unreactive compared to other elements.
