Question

Based on their positions in the periodic table, rank the following atoms in order of increasing first ionization energy: F, Li, N, Rb

a) Rb, Li, F, N
b) Li, F, N, Rb
c) F, N, Li, Rb
d) N, F, Li, Rb

Answer 1

Atoms Rb, Li, N, and F are ranked in terms of increasing first ionization energy based on their group and period trends in the periodic table, with the correct order being Rb, Li, N, and finally, F.

Step-by-step explanation:

To rank the atoms F, Li, N, and Rb in order of increasing first ionization energy, we need to consider two trends in the periodic table: ionization energy increases as we move from left to right across a period and increases from bottom to top within a group.

Therefore, the correct order is Rb (which is on the bottom left), followed by Li (in the same group but in a higher period), then N (further to the right within the same period as Li), and finally F (to the right of N and in a higher period compared to Rb and Li).

The correct order is: Rb, Li, N, F. This takes into account both the group and period trends for ionization energy in the periodic table.
