Nomenclature of elements beyond atomic number 100 MCQs with solutions
10 of the 12 published questions on this topic, exactly as they appear in a test. Answers and worked solutions come with your result rather than on this page.
Systematic temporary names for newly discovered elements are constructed from
- A. numerical roots corresponding to the digits of atomic number
- B. the discoverer's first name only
- C. the colour of the element
- D. its melting point
In the systematic temporary naming scheme, the suffix used for an element name is
- A. -ium
- B. -ide
- C. -ate
- D. -ous
The symbol of a systematically named temporary element is formed from
- A. the initial letters of the numerical roots
- B. the last two letters of the final name
- C. the discoverer's initials
- D. the atomic mass
The temporary systematic naming scheme is mainly useful before
- A. a permanent official name is adopted
- B. the atomic number is known
- C. the element exists
- D. any chemical study is possible
Using the roots un (1), nil (0) and quad (4), atomic number 104 would be systematically named
- A. unnilquadium
- B. ununquadium
- C. unquadnilium
- D. nilunquadium
Using the roots un (1), bi (2) and tri (3), atomic number 123 would be named
- A. unbitrium
- B. bitr iunium
- C. untribium
- D. tribiunium
The temporary symbol for systematic name unnilquadium would be formed from the initials
- A. Unq
- B. Uqn
- C. Nqu
- D. Uqq
A provisional name built from digit roots corresponding to 1-1-8 refers to atomic number
- A. 118
- B. 108
- C. 1108
- D. 18
Why is a systematic temporary naming scheme useful for superheavy elements?
- A. It provides an unambiguous name tied to atomic number before a permanent name is approved
- B. It predicts chemical properties exactly
- C. It replaces atomic number
- D. It gives the isotope mass automatically
If a provisional element has atomic number 120, which digit sequence must its temporary name encode?
- A. 1-2-0
- B. 12-0
- C. 1-20
- D. 120 as one root
Common mistakes in Nomenclature of elements beyond atomic number 100
Recorded against questions in this topic that are not shown above, so none of these points at an answer you can see on this page.
- Applies ordinary permanent-symbol rules to the temporary systematic scheme.
- Changes the digit order or derives the symbol from the final name rather than the root initials.
