![]() In terms of its electron configuration can you explain why hydrogen can form both cations and anions? Feel free to post in the comments at the end of the article! A hydrogen cation a hydrogen atom and a hydrogen anion. Most elements much prefer to form only one or the other. Note Hydrogen is actually somewhat unusual in that it readily forms both cations and anions. We can illustrate this by examining some very simple cations and anions those formed when a single hydrogen atom loses or gains an electron. The result is that the atom becomes an anion-an ion with a net negative charge. When a neutral atom gains one or more electrons the number of electrons increases while the number of protons in the nucleus remains the same. The result is that the atom becomes a cation-an ion with a net positive charge. See full list on When a neutral atom loses one or more electrons the total number of electrons decreases while the number of protons in the nucleus remains the same. Cations and anions When a neutral atom loses one or more electrons the total number of electrons decreases while the number of protons in the nucleus remains the same. The resulting charged species is called an ion. Most atoms however can either gain or lose electrons when they do so the number of electrons becomes different from the number of protons in the nucleus. The result is that the total positive charge of the protons cancels out the total negative charge of the electrons so that the net charge of the atom is zero. ![]() Image credit Wikipedia Commons public domain Atoms are electrically neutral because the number of protons which carry a 1+ charge in the nucleus of an atom is equal to the number of electrons which carry a 1- charge in the atom. ![]() Sodium chloride is an ionic compound made up of sodium ions and chloride ions in a crystal lattice.
