Step 1: Identify the element with atomic number 105.
The element with atomic number 105 is known as Dubnium (Db), named after the Russian town of Dubna where the element was first synthesized.
Step 2: Define the IUPAC naming convention.
The IUPAC system of naming elements uses a systematic approach based on the atomic number of an element. The name is derived by combining the Latin words for the digits of the atomic number.
Step 3: Apply the IUPAC naming rule to element 105.
For element 105, the IUPAC name follows this rule and is derived as "dubnium," using the root "dubn" from Dubna, where the element was discovered.
