And unfortunately, the helium atoms in liquid helium are right on top of each other. of huge clouds of hydrogen and helium atoms, and they have no structure.

H E L I U M # E # N From the Greek "Helios" meaning "the sun", since it was detected in The nucleus of the helium atom consists of two protons and two neutrons. It is sometimes referred to as the alpha particle and was first observed in the decay of heavy radioactive nuclei. 6-4 Atomic structure – Physics 1.0 Figure 1 shows a helium atom.

Helium is composed of two electrons bound by the electromagnetic force to a nucleus containing two protons along with either one or two neutrons, depending on the isotope, held together by the strong force. Helium is a chemical element with atomic number 2 which means there are 2 protons and 2 electrons in the atomic structure.

The atomic number often is not included because the element name (or element symbol) also tells the number of protons. If the number of protons changes, then it becomes a different element. For example, helium will always have 2 protons; if you add a proton then it becomes lithium (Li).

Atomic Number – Protons, Electrons and Neutrons in Helium. Helium is a chemical element with atomic number 2 which means there are 2 protons in its nucleus.Total number of protons in the nucleus is called the atomic number of the atom and is given the symbol Z.The total electrical charge of the nucleus is therefore +Ze, where e (elementary charge) equals to 1,602 x 10-19 coulombs.
