Why do elements always end in IUM?
The -ium suffix is a Latin suffix which forms abstract nouns, thus it is used to form chemical elements’ name from its naming origin, such as minerals (calcium from calx) or person names (gadolinium).
How many elements end with the suffix ium?
Have you looked at a periodic table, or perhaps an alphabetic list of the elements (with their symbols)? This is not a question that you should need any help with. All metals should end in ium, and U.S. chemists even agreed a few years back to properly call element 13 aluminium, as the rest of the world does.
What is BU on the periodic table?

Where does ium come from?
The –ium in helium can be thought of as carrying the meaning “derived from,” with the hel- part representing Greek helios, “sun,” it having been inferred that helium was present in the sun’s atmosphere. This same derivative principle is behind potassium (from potash), sodium (from soda), and magnesium (from magnesia).
Why do all metallic elements have a suffix ending in -ium?
The names sodium and potassium were changed to natrium and kalium. All metallic elements discovered after this date ($1811$) have been given names ending in -ium (occasionally -um). Examples are cadmium, lanthanum, lithium, thallium, radium. This is also why helium has the suffix.
What is the name of the element that starts with IUM?
4 Answers. The names sodium and potassium were changed to natrium and kalium. All metallic elements discovered after this date () have been given names ending in – ium (occasionally – um ). Examples are cadmium, lanthanum, lithium, thallium, radium.
Why do most chemical names end in -um?
The Origins of Chemical Names. 1963, Oldbourne, London. Well, they end in -um because it’s a good Latin neuter singular of the second declension: that is, it’s a way you can refer to ‘stuff’ of the sun (helios), or of Magnesia (where magnesium and magnetic stuff was found), of lime (calx, calcis).
Why do some elements have the suffix i at the end?
Some elements have -ium because they’re derived from stems that have an -i at the end, like the ones listed above. But others, like lithium, don’t actually have an -i at the end of the stem etymologically (cf. Ancient Greek lithos).
