Hydrogen

In 1913, Niels Bohr proposed the atomic Hydrogen hypothesis. It is  a positively charged nucleus made up of protons and neutrons that is surrounded by a negatively charged electron cloud, according to him. In the model, electrons are arranged in atomic shells around the nucleus. Electrostatic interactions between the positive nucleus and the negative surrounds […]

The lightest substance in the universe is Hydrogen. In the periodic table, this is the first element. It also has similarities to alkali metals and halogens. However, scientists have discovered Hydrogen in a metallic state in recent studies and experiments. Like other alkali metals, it contains one electron in its valence shell and produces the
