Story highlights Nihonium, moscovium, tennessine and oganesson are the newest elements to receive names

The elements were recognized by the International Union of Pure and Applied Chemistry in December

(CNN) Meet nihonium (Nh), moscovium (Mc), tennessine (Ts) and oganesson (Og), the newest elements on the periodic table to receive names. But don't get too attached to the nomenclature for these elements, formerly known by their respective atomic numbers 113, 115, 117 and 118. The names are on a five-month probation before things are made official.

The elements were recognized by the International Union of Pure and Applied Chemistry , or IUPAC, the U.S.-based world authority on chemistry, on December 30, 2015. Their addition completed the seventh row of the periodic table.

The discoverers of the elements were invited to propose the names, and now a public review of the names begins, expiring on November 8, 2016. If you feel strongly about these names, the union invites you to provide comments and feedback here.

IUPAC provided the discoverers with guidelines to assist them in creating the names. These names keep with the longstanding tradition of being named after a mythological concept or character (including an astronomical object), a mineral or similar substance, a place or geographical region, a property of the element or a scientist.

And of course, they must end in "-ium," "-ine," or "-on" depending on the grouping of elements they belong to. IUPAC also prefers the names translate easily across major languages.
