Answer: Option (d) is the correct answer.

Explanation:

It is known that reactivity of atoms increases on moving down the group. This is because on moving down the group there is also increase in number of shells.

As a result, outer shell electrons move away from the nucleus and thus force of attraction between the nucleus and electrons decreases.

Hence, it is easy to remove the electrons from outermost shell and thus reactivity of atom increases.

Therefore, we can conclude that the given elements are group 1 elements and largest of them is rubidium. Thus, out of the given options, rubidium element is the most reactive.

What statement best describes an independent variable?
prisoha [69]
<span>Answer : D. The factor that's changed by the experimenter and impacts the dependent variable.<span>

</span><span>An independent variable is a variable in which you can manipulate or control while the dependent variable depends on the independent variable. An example of an independent variable is the running while the dependent variable is your pulse rate. The pulse rate depends on how fast and how long is the distance of your run. The pulse rate maybe higher and faster if you’ve run quite long and will be close to stable if you only run for a short distance and slow speed.</span></span>
