which of the following is true regarding the inner transition elements?
A. their valence electrons can be located in both s and f sublevels
B. They occupy the d block of the periodic table
C. These include the lanthanides and actinides and do not have f sublevels
chemistry
D. These include all elements in groups 3-12
I've been waiting on you to show some work and that hasn't happened yet. Please indicate your answers and why you think that is the answer.
nvm its not c sorry
To determine which of the given statements is true regarding the inner transition elements, we need to understand the characteristics and positions of these elements in the periodic table.
The inner transition elements are located in the f-block of the periodic table, which consists of two series: the lanthanides and the actinides.
Statement A: "Their valence electrons can be located in both s and f sublevels."
This statement is not true. The valence electrons for the inner transition elements are generally located in the f sublevel. The s sublevel is already filled for these elements.
Statement B: "They occupy the d block of the periodic table."
This statement is not true. The inner transition elements are actually located below the main body of the periodic table in the f-block. The d-block elements occupy groups 3-12.
Statement C: "These include the lanthanides and actinides and do not have f sublevels."
This statement is not true. The inner transition elements specifically refer to the lanthanides and actinides, and they do have f sublevels. These elements have a unique electronic configuration where the f sublevels are progressively filled.
Statement D: "These include all elements in groups 3-12."
This statement is not true. Group 3-12 elements are actually part of the d-block, not the inner transition elements.
In conclusion, none of the given statements are true regarding the inner transition elements.
