Which atomic model best explains the helium atom?
The quantum mechanical model best explains the helium atom. In this model, electrons occupy specific energy levels and exist in probabilistic electron clouds around the nucleus, rather than following fixed orbits. The helium atom has two electrons that exhibit both wave-like and particle-like behavior, occupying a region of space defined by their quantum states. This model accounts for the observed properties of helium, including its stability and the behavior of its electrons in interactions with other atoms.
Is the smallest unit of a chemical compound that retains the properties of the compound?
Molecule
If the mass of water is 4.5 times greater than the mass of helium how does the mass of a water molecule compare with the mass of a helium atom?
The mass of the water molecules is greater than the mass of the helium atoms. It just so happens I had the same question in science, and that's what I put down. It might be wrong, it might not. But I'd be at least at like 65-35% chance it's right.
How many atoms does a monatomic have?
A monatomic molecule contains only one atom. It is a single atom that is chemically stable. Examples include noble gases like helium and neon.
Why doesnt bohrs model work for helium?
Bohr's model of the hydrogen atom works well for atoms with only one electron like hydrogen, but it fails for helium because helium has more than one electron. The model does not account for the repulsion between the two electrons in the helium atom, leading to inaccurate predictions of its behavior.
Where does the sun gets energy from and goes to light and heat?
The sun uses nuclear fusion to produce light and energy. the process is relatively complicated but simplified it looks something like this. step 1: hydrogen atom + hydrogen atom = deutrerium atom (an isotope of hydrogen (one extra neutron)) + positron + neutrino step 2: Deutrerium atom + hydrogen atom = helium 3 (an isotope of Helium (missing one neutron)) + energy step 3: helium 3 atom + helium 3 atom = helium atom + hydrogen atom + hydrogen atom + energy.
What part of an atom determines what element type of stuff like helium iron uranium etc it is?
The number of protons (in nucleus) or the number of electrons in a neutral atom.

Is helium a molecule?
Helium is an atom. Heavier elements have molecules.
What does a atom look like after nuclear fusion?
The most likely form of fusion to be successful on earth will be to produce helium from hydrogen isotopes. Helium has two protons and two neutrons in its nucleus.
Is the smallest unit of a chemical compound that retains the properties of the compound?
Molecule
Is it true stars like the sun burn hydrogen producing helium?
All stars fuse hydrogen into helium - the slight difference in atomic weight between 4 hydrogen atoms and one helium atom, is given off as radiation.

What substance is made of only one atom?
An element is a pure substance that is made up of only one kind of atom.Elements that can exist as a single atom are the noble gases in Group 18 of the periodic table.
What atom does a model of an atom project have?
It can be any atom if you have to explain the basic structure of it. But there should be the main parts like the nucleus,shells,protons,neutrons,electrons,etc.
