Define anion and cation - Study guides, Class notes & Summaries

What is the difference between cations and anions? - Cation is the loss of electrons, the atom becomes more positive. Anion is the gain of electrons, the atom becomes more negative. Differentiate between mass number and atomic number. - Mass number- number of protons and neutrons. Atomic number- number of protons What are valence electrons and what is their significance? - Valence electrons are electrons in the outermost shell of an atom. They are important in determining the bonds that the...
