An ion is an atom that has gained or lost electrons. Isotopes are atoms of the same element that have different amounts of neutrons. In both ions and isotopes, the number of protons remains constant. The number of proton... More »

The difference between atoms, ions and isotopes is the number of subatomic particles. An atom is the basic building block of matter, the smallest molecule of an element that exists and that cannot be chemically divided b... More »

The isotope with 13 protons and 14 neutrons is aluminum-14. The element of the isotope can be determined by either the number of electrons or protons, which are equal to the atomic number of an element. In the case of al... More »

During the first two stages of photosynthesis, enzymes break up the electrons from water molecules to yield oxygen gas and hydrogen ions. When photosynthesis reaches the third stage, or Calvin cycle, enzymes assist in th... More »

A metallic bond forms when the valence electrons are not associated with a particular atom or ion. Instead, they exist as a "cloud" of electrons around the ion centers. More »

When an atom or group of atoms loses or gains electrons or protons, it becomes an ion. The primary difference between normal atoms and ions is that normal atoms typically have a neutral charge while ions are either posit... More »
