d and f BLOCK ELEMENTS MCQ Quiz: GKFix - Bridge of Knowledge

Question 2081

▼

Which of the following elements is a member of the 6d transition series?

▼

Why are the f-block elements sometimes called 'inner transition metals'?

Because they are located inside the main periodic table
Because they were discovered after the main transition metals
Because the d or f orbitals being filled are inner shells, shielded by outer electron shells
Because they have lower energy than other transition metals

▼

What is the main difference between the electronic configurations of typical transition metals and those of Zinc, Cadmium, and Mercury?

Typical transition metals have s electrons, while Zn, Cd, and Hg have d electrons
Typical transition metals have complete d subshells, while Zn, Cd, and Hg have incomplete d subshells
Typical transition metals have incomplete d subshells, while Zn, Cd, and Hg have complete d10 subshells
There is no significant difference in their electronic configurations

▼

Which transition metal series includes the element Rutherfordium (Rf)?

▼

What is the primary reason for placing f-block elements separately at the bottom of the periodic table?

Because they are all radioactive
Because they were discovered later
To maintain the table's structure and readability while grouping elements with similar f-orbital filling
Because they have very high atomic masses
