based on its location on the periodic table, which metal is likely to be less reactive than rubidium and more reactive than calcium?\npotassium (k)\ncesium (cs)\nmagnesium (mg)\ntitanium (ti)

based on its location on the periodic table, which metal is likely to be less reactive than rubidium and more reactive than calcium?\npotassium (k)\ncesium (cs)\nmagnesium (mg)\ntitanium (ti)

Answer

Brief Explanations:

Reactivity of metals increases down a group and decreases across a period. Rubidium (Rb) is in Group 1, calcium (Ca) is in Group 2. Potassium (K) is also in Group 1 above Rb, so it is less reactive than Rb and more reactive than Ca which is in Group 2. Cesium (Cs) is below Rb in Group 1 and is more reactive than Rb. Magnesium (Mg) in Group 2 is less reactive than Ca. Titanium (Ti) is a transition - metal and less reactive than Group 1 and 2 metals.

Answer:

A. potassium (K)
