Helium atoms only need how many valence electrons to have a filled outermost energy level?
Helium is already full. Helium atoms only need 2 electrons to be full, and Helium, as an element, already has 2.
Is balloons filled with helium a chemical change?
A balloon is filled with helium. Athough, it can be a chemical and physical change. For example you can take the helium out of the balloon, but you cant put it back in it now that its already in the air.
What family already has an octet?
The noble gases (helium, neon, argon, krypton, xenon).
How many valence electrons does helium need to gain to have a filled outermost energy level?
0 It already is full
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 doesn't helium react with?
Because the valence electron shell is already filled.
How many electrons does it take for hydrogen and helium to become stable?
Helium is already stable. Hydrogen should gain or lose one electron to be stable.
What family already has an octet?
The noble gases (helium, neon, argon, krypton, xenon).
Name something you filla balloon with?
I personally fill a balloon with my breath, the balloons I buy are already filled with helium.
How many valence electrons does helium need to gain to have a filled outermost energy level?
0 It already is full
Does the sun help produce hydrogen?
No. The sun is already made mostly of hydrogen and is actually consuming the hydrogen in its core and turning it into helium.
How could xenon achieve a stable octet?
Xenon, like all the noble gases except helium, already has a stable octet!
What is the element name for He?
Helium Helium
Would helium become a positive ion before bonding yes or no?
No. Helium is a noble gas. It does not want to gain or lose electrons as it already has a full valence shell. In order to become a positive ion it would need to lose an electron.
