Sodium sulfate (also known as sodium sulphate or sulfate of soda) is the inorganic compound with formula Na 2 SO 4 as well as several related hydrates. All forms are white solids that are highly soluble in water. With an annual production of 6 million tonnes, the decahydrate is a major commodity chemical product.

The charge numbers for ions (and also subatomic particles) are written in superscript, e.g. Na + is a sodium ion with charge number positive one (an electric charge of one elementary charge). Atomic numbers (Z) are a special case of charge numbers, referring to the charge number of an atomic nucleus, as opposed to the net charge of an atom or ion

Jan 31, 2024 · Since atoms are typically neutral (overall charge = 0), the number of electrons (each with a charge of -1) in an atom is equal to the number of protons (each with a charge of +1). Hydrogen atoms all have one electron occupying the space outside of the nucleus. Helium, with two protons, will have two electrons.
Sodium chloride is an ionic compound made up of sodium ions and chloride ions in a crystal lattice. 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.
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 result is that the atom becomes a cation—an ion with a net positive charge. For example, the element sodium loses one electron to become a cation:
Sep 17, 2020 · Here are two charts. The first shows common element charges, while the second shows all the element charges for the first 45 elements (most common charges in bold). For a single atom, the charge is the number of protons minus the number of electrons. Find the charge by balancing charge in a compound. Number.
This indicates that sodium is in the +1 charge state, rather than the elemental form of sodium (which has an equal number of protons and electrons and is neutral in charge). Using the ion naming system when referring to ions, rather than the elemental names of atoms is important, as the reactivity of the ion vs the elemental form of a substance ...
