Hydrogen is an element. Its atomic number is one. It has one proton in the nucleus, and one electron in the first orbital. It has no neutrons.
Hydrogen is a chemical element represented by the symbol H and an atomic number of 1. At standard temperature and pressure it is a colorless, odorless, nonmetallic, tasteless, highly flammable diatomic gas (H2). With an Atomic Mass of 1.00794 g/mol, hydrogen is the lightest element.
Hydrogen is the most abundant of the chemical elements, constituting roughly 75% of the universe's elemental mass.
The most common naturally occurring isotope of hydrogen, known as protium, has a single proton and no neutrons.
it is the lightest of all gases and the most abundant element in the universe.
becaus it has the simplest electron configuration
It has only one proton (except for the occasional deuterium atom), and only one electron.
The simplest element from an atomic structure point of view is hydrogen with just one proton and one electron. Its chemistry is by no mean simple!
Hydrogen is an element. Its atomic number is one. It has one proton in the nucleus, and one electron in the first orbital. It has no neutrons.
Helium has completely filled orbitals and is stable whereas hydrogen has one valence electron and is reactive.
Hydrogen is a non metal element. Atomic mass of it is 1.0079.
