Atoms are a bit like people: they usually prefer company to being alone. A lot of atoms prefer to join up with other atoms because they're more stable that way. So hydrogen atoms don't exist by themselves: instead, they pair up to make what is called a molecule of hydrogen. A molecu...
protons and neutrons. Electrons have a negative charge, protons have an equal positive charge, and neutrons have no charge. An atom has an equal number of electrons and protons, which makes it electrostatically neutral, but if electrostatic neutrality was all that mattered, atoms would never combi...

Atoms are therefore extremely small (the hydrogen atom is the smallest) and are sometimes described as the "basic building blocks of matter". This description makes more sense the more chemistry you have studied because a large aspect of the study of chemistry concerns learning about how, why...
Hydrogen is the simplest chemical element, or type of atom. It consists of just one proton and one electron. It is also the most abundant element, making up around 75% of the known matter in the universe. Vast amounts of hydrogen exist in water and living things. ...
