The protons, neutrons, and electrons in the atoms of iron and gold are identical—there are just different numbers of them. In theory, you could turn iron into gold by taking iron atoms and adding 53 protons, 88 neutrons, and 53 electrons to each one. But if that were as easy as it...

To be an element, a substance has to at least have protons, since these particles define the type of element. Elements consist of atoms, which contain a nucleus of protons and neutrons surrounded by a cloud or shell of electrons. Elements are considered the basic building blocks of matter be...

The absorption of a smaller tribe into a larger The absorption of bodies in a whirlpool Resorption (medicine) The loss and reassimilation of bone (or other) material. Absorption The imbibing or reception by molecular or chemical action, of radiant energy; the process of being neutrons being ab...
A line of radioactive cosmetics introduced in 1930 Each element comes in varieties called isotopes whose atoms differ in the number of neutrons in their nuclei. You’ve probably heard of uranium-235 and, well, the polonium-210 that did in former KGB officer Alexander Litvinenko. The former is...
The Difference Between a Cation and an Anion By Todd Helmenstine An atom consists of three types of subatomic particles: neutrons, protons, and electrons. Neutrons and protons are both located in the nucleus of the atom; neutrons are neutrally charged particles, and protons are positively charged...
