The answer is <span>a. Rubidium

A cation is an ion that has a positive charge. The charge positive because it loses electrons. The radius of an atom is influenced by the electron because it is found at the outer layer of the atom. Since cation has less electron and anion get more electron, the radius of cation will be smaller than anion. 
Rubidium is the biggest cation because it is located in the lowest row, thus having most electron count.</span>

Based on the vibrational difference you observed, state a hypothesis to explain why diatomic molecules in the air, such as oxyge
mihalych1998 [28]

Answer:

See explanation

Explanation:

The ability of a gas to function as a green house gas depends on its ability to absorb infra red rays. In turn, the absorption of infrared red rays depends on whether or not the molecule is IR active.

The triatomic molecules such as methane and water are IR active. Only IR active molecules can lead to green house effect.

Note that for a molecular vibrational mode to be IR active, the dipole moment of the molecule is changed as the vibration occurs .
