What else can I help you with?
Helium atoms only need how many valence electrons to have a filled outermost energy level?
Helium atoms only need 2 valence electrons to have a filled outermost energy level because helium is in the first period of the periodic table and its outermost energy level can only hold a maximum of 2 electrons.
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).
Does compressed helium lift more?
Compressed helium does not lift more than regular helium. The lifting force generated by a gas is determined by its density, regardless of whether it is compressed or not. Helium is already a very low-density gas, so compressing it would not significantly increase its lifting capacity.
What type of molecules is helium likely to form?
Helium is a noble gas and is unlikely to form molecules because it already has a full outer electron shell, making it very stable. Helium typically exists as single atoms rather than forming molecules with other elements.

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.

How many valence electrons does helium need to gain to have a filled outermost energy level?
0 It already is full
Name something you filla balloon with?
I personally fill a balloon with my breath, the balloons I buy are already filled with helium.
What group of elements already has a full shell?
Noble gases already has full valence shell
Why Helium will not react with anything because it has a complete outer electron shell?
Helium is a noble gas with a full outer electron shell, making it stable and unreactive. Its electron configuration is already stable, so it has little tendency to gain, lose, or share electrons with other elements to form chemical bonds. This inertness is why helium does not readily react with other elements.
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.
