how many electrons does hydrogen have?

Hydrogen is the lightest and most abundant element in the universe. It is the first element on the periodic table and has the atomic symbol H and atomic number 1. Hydrogen is a chemical element that is made up of one proton and one electron. The proton is located in the nucleus of the hydrogen atom, while the electron is located in the electron shell surrounding the nucleus.

Hydrogen has only one electron, which is located in the outermost electron shell. The electron shell is a region around the nucleus of an atom where electrons are found. In an atom, the number of electrons in the outermost electron shell is equal to the atomic number of the element, which is the number of protons in the nucleus. Since hydrogen has an atomic number of 1, it has one electron in its outermost electron shell.

Hydrogen is a highly reactive element and can easily form chemical bonds with other elements. It is often found in compounds, such as water (H2O), which is a compound made up of two hydrogen atoms bonded to one oxygen atom. Hydrogen is also used in a variety of industrial processes, including the production of fuels and chemicals.

In addition to its use in industry, hydrogen is also being explored as a potential clean energy source. Hydrogen fuel cells, which use hydrogen to generate electricity, are being developed as a way to power vehicles and other devices without emitting harmful greenhouse gases.
