What is the basis of naming the element curium?
Curium is named in honour of Pierre and Marie Curie, who pioneered the study of radioactivity in the final days of the 19th century. Nineteen radioisotopes of curium are known to exist, the first of which, 242Cu was isolated in the hydroxide form in 1947 and in its elemental form in 1951.

How are elements named after people or places?
Newly discovered elements may be named for a person, place, mythological reference, property, or mineral. Examples include einsteinium (named for Albert Einstein), californium (named for California), helium (named for the sun god Helios), and calcium (named for the mineral calyx). Elements are named by their official discoverer.
How are strong bases and weak bases named?
Naming Bases. Most strong bases contain hydroxide, a polyatomic ion. Therefore, strong bases are named following the rules for naming ionic compounds. For example, NaOH is sodium hydroxide, KOH is potassium hydroxide, and Ca(OH) 2 is calcium hydroxide. Weak bases made of ionic compounds are also named using the ionic naming system.
How are the names and symbols of elements determined?
Official element names and symbols are determined by the International Union of Pure and Applied Chemistry (IUPAC). However, elements often have common names and symbols in various countries. Elements don’t gain official names and symbols until after their discovery has been verified. Then, a name and symbol may be proposed by the discoverer.
How are acids and bases named in chemistry?
In simple binary acids, one ion is attached to hydrogen. Names for such acids consist of the prefix “hydro-“, the first syllable of the anion, and the suffix “-ic”. Complex acid compounds have oxygen in them. Strong bases with “-OH” (hydroxide) groups are named like ionic compounds.
