Helium has a nuclear charge of +2 and 2 electrons in a 1s orbital. Hydrogen has a nuclear charge of +1 and just one electron in a 1s orbital. The extra charge on the nuclees means that the electrons in He are more tightly bound than in hydrogen thuis reflected in the ionization energy of 2372 kJ/mol for He and about 1312 kJ/mol for hydrogen. For helium t the "outer shell" is full, a "stable " configuration.

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.
How is the nucleus of the hydrogen atom different from the nucleus of the helium atoms?
The hydrogen nucleus has a single proton. The helium nucleus has two protons and one or two neutrons.
What do you get when you join one atom of Hydrogen and one atom of Helium?
When you join one atom of hydrogen and one atom of helium, you get a molecule with the chemical formula HHe. This is not a stable combination as the resulting molecule is highly reactive due to the different properties of hydrogen and helium atoms.
After a single subatomic particle is removed from an atom of helium the helium atom becomes an atom of hydrogen What subatomic particle was removed?
A single proton was most likely removed from the helium atom to result in an atom of hydrogen. Helium typically has two protons, so removing one proton would leave one, transforming it into hydrogen, which has one proton.
How many different types of atoms are in helium?
Helium atoms do not contain different types of atoms. Each helium atom consists of two protons and two neutrons in its nucleus, with two electrons orbiting around the nucleus.
How is the nucleus of the hydrogen atom different from the nucleus helium atom?
The nucleus of hydrogen has 1 proton, whereas that of helium has 2 protons.
How is the nucleus of hydrogen atom different from the nucleus of the helium atom?
The nucleus of hydrogen has 1 proton, whereas that of helium has 2 protons.

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.

When you join one atom of hydrogen and one atom of helium, you get a molecule with the chemical formula HHe. This is not a stable combination as the resulting molecule is highly reactive due to the different properties of hydrogen and helium atoms.
Does helium have hydrogen in it?
No. Helium and Hydrogen are two different elements.

A single proton was most likely removed from the helium atom to result in an atom of hydrogen. Helium typically has two protons, so removing one proton would leave one, transforming it into hydrogen, which has one proton.
Is an alpha particle identical to the nucleus of a hydrogen atom?
No, it is identical to that of a helium atom.
How many different types of atoms are in helium?
Helium atoms do not contain different types of atoms. Each helium atom consists of two protons and two neutrons in its nucleus, with two electrons orbiting around the nucleus.
How does hydrogen occur?
When two hydrogen atoms fuse to become one helium atom.
Number of hydrogen atom fuse to form helium atom?
In nuclear fusion, four hydrogen atoms fuse together to form one helium atom. This process releases a large amount of energy in the form of heat and light.
