Helium Structure

Helium (He) is the second element in the periodic table, with an atomic number of 2. It is a colorless, odorless, non-flammable, and inert gas that is the lightest and most abundant element in the universe. Helium is found in small amounts in the Earth’s atmosphere and is also produced by the radioactive decay of uranium and thorium.

Atomic Structure of Helium

Helium has two protons, two neutrons, and two electrons. The protons and neutrons are located in the nucleus of the atom, while the electrons orbit the nucleus in shells. Helium has one electron shell, which is filled with two electrons.

The electron configuration of helium is $1s^2$. This means that the two electrons in helium are located in the 1s orbital. The 1s orbital is the lowest energy orbital in an atom, and it can hold a maximum of two electrons.

Physical Properties of Helium

Helium is a gas at room temperature and pressure. It has a boiling point of -268.9 degrees Celsius and a melting point of -272.2 degrees Celsius. Helium is the lightest element and has a density of 0.1786 grams per liter at room temperature and pressure.

Helium is a very good conductor of heat and electricity. It is also a very inert gas and does not react with other elements under normal conditions.

Chemical Properties of Helium

Helium is a noble gas and does not react with other elements under normal conditions. This is because the electron shell of helium is completely filled, and it does not need to gain or lose electrons to achieve a stable configuration.
