A helium atom is four times lighter than a carbon atom. This is because helium has two protons and two neutrons in its nucleus, while carbon has six protons and six neutrons. The atomic mass of helium is approximately 4 atomic mass units, while the atomic mass of carbon is approximately 12 atomic mass units.

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?
A carbon atom has more protons, neutrons, and electrons than a helium atom. This gives carbon different chemical properties and the ability to form larger and more complex molecules compared to helium.
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.
Why is helium lighter than CO2?
Helium is lighter than CO2 because it has a lower atomic mass. Helium is made up of two protons and two neutrons, while CO2 is made up of one carbon atom and two oxygen atoms. The overall molecular weight of helium is much lower than that of CO2, making it lighter.

How many times heavier is a sulfur atom than a helium atom?
A sulfur atom is about 32 times heavier than a helium atom. This is based on the atomic masses of sulfur (32 amu) and helium (4 amu).
Is an alpha particle identical to the nucleus of a carbon atom?
No, it is identical to the nucleus of a helium atom.
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
An atom of helium has a mass about four times greater than that of an atom of hydrogen Which choice makes the correct comparison of the relative numbers of helium and hydrogen atoms in equal masses o?
An equal mass of helium would contain fewer atoms compared to hydrogen, as each helium atom is four times heavier than a hydrogen atom. This is because the atomic mass of a helium atom is roughly four times that of a hydrogen atom.
Which of the Following statements about helium atom in the sun and helium atom on earth false?
Both helium atoms in the sun and on Earth have the same properties, as they are identical in terms of their atomic structure and behavior. The only difference is in the environment in which they exist.
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.
