What is the diameter of the helium atom?
The nucleus of a Helium atom contains two protons and two neutrons, protons and neutrons are measured in Daltons, and a Helium atom is about 4 Daltons
What more does a carbon atom have than a helium atom?
Helium has 2 protons, 2 electrons. Carbon has 6 protons, 6 electrons.
What atom is 4.65 times as great as the mass of carbon 12?
Helium has atomic mass 4.003 a.m.u.
Why is helium heavier than air?
Helium is lighter than air because of atomic mass. Helium is element number two, whereas oxygen is element number 8. Oxygen has an atomic mass of 16, and helium has a mass of 4, so helium is 4 times lighter than air. (Atomic mass is the total mass of protons, neutrons, and electrons in a single atom.)
Is an alpha particle identical to the nucleus of a carbon atom?
No, it is identical to the nucleus of a helium atom.
What type of bond would be formed between a carbon atom and a helium atom?
Helium will not react with carbon as helium is chemically inert.

No, it is identical to the nucleus of a helium atom.
Why is helium different than carbon with energy?
In quite a lot of ways. --> Helium has two electrons whilst hydrogen has one --> Helium is a noble gas --> Helium is a bigger atom --> Helium's symbol (He) has an "e" compared to hydrogen's symbol (H) --> Helium is less reactive --> Helium doesn't create H-bonds
How many Helium-atoms and Carbon-atoms do you have if you have He-atoms with mass of 40amu and C-atoms with mass of 120amu?
Mass of 1 Helium atom is 4 amu and mass of 1 Carbon atom is 12 amu. So there are 10 helium atoms and 10 carbon atoms
How many times heavier is a sulfur atom than a helium atom?
8 Times Heavier
Which of the Following statements about helium atom in the sun and helium atom on earth false?
c.one will be five times more massive.
Why is helium lighter then air?
The air is made up of different elements, such a oxygen, carbon dioxide, nitrogen and argon. On the periodic table, you can see that the relative atomic mass is bigger for these elements that that of helium. Relative atomic mass is not the actual weight of the atom, that would be too hard to find. Therefore scientists use this to show how big some atoms are compared to others. I', unsure, but I think the helium atom has an RAM of 2, and oxygen for example has a RAM of 16. Therefore, helium is lighter. That's why balloons float. How super.
How many times greater is the mass of bromine atom compared to a helium atom?
18.96 times greater = 19.96 times as great.
