What is the difference between an anion and a cation?
Atoms are the smallest units of a chemical element, and they consist of three main parts: protons, neutrons, and electrons. Protons and neutrons are found in the nucleus, which is the central part of the atom, while electrons orbit around the nucleus. The number of protons in an atom determines the element of an atom, and each element has a unique number of protons in its atoms, known as the atomic number. chemsheets atoms and ions 2 answers
