Helium is a chemical element with the symbol He and atomic number 2. It is a colorless, odorless, tasteless, non-toxic, inert, monatomic gas, the first in the noble

The most important chemical properties of helium include its atomic mass, state of matter, boiling and melting points, and density. This number is very important because it is unique for atoms of a given element. All atoms of an element have the same number of protons, and every element has a different number of protons in its atoms. For example, all helium atoms have two protons, and no other elements have atoms with two protons. In the case of helium, the atomic number is 2.

The atomic number does not change when an atom becomes an ion. This is because the atomic number is the number of protons in the nucleus, and an ion is formed when an atom gains or loses electrons, which are located in the electron cloud surrounding the nucleus. Helium, with an atomic number of 2 and He as its element symbol, is a unique element It's average atomic mass is 4.003, and has 2 protons (because that is the same as the atomic number It has 2 electrons (since the number of electrons is the same as the number of protons) and 2 neutrons in regular atoms (since it's the atomic mass, 4, subtracted by the number of protons, 2). Video explains how to use the Periodic Table components to create a Helium Atom Bohr Model.

This is because the atomic number is the number of protons in the nucleus, and an ion is formed when an atom gains or loses electrons, which are located in the electron cloud surrounding the nucleus. Helium, a chemical element with the symbol He and atomic number 2, is a colorless, odorless, tasteless inert gas.It is the second lightest and abundant chemical species after hydrogen. It has the lowest boiling point among the elements in the periodic table.
