Question

Elements are organized on the periodic table based on their properties. Which statement correctly predicts and explains the chemical reactivity of two metals? Rubidium (Rb) is more reactive than strontium (Sr) because strontium atoms must lose more electrons. Sodium (Na) is more reactive than magnesium (Mg) because sodium atoms must gain more electrons. Calcium (Ca) is less reactive than potassium (K) because potassium atoms must lose more electrons. Beryllium (Be) is less reactive than lithium (Li) because beryllium atoms must gain more electrons.

Answer 1

We know that elements are organized on the periodic table based on their properties.

The statement correctly predicting and explaining the chemical reactivity of two metals is given below -Rubidium (Rb) is more reactive than strontium (Sr) because strontium atoms must lose more electrons.

Rubidium belong to Alkaline group 1 and Strontium belong to Alkaline group 2.

Answer 2

Answer:

The correct statement about the reactivity of metal is option A, rubidium (Rb) is more reactive than strontium (Sr) because strontium atoms must lose more electrons. Further explanation: Reactivity is defined as the tendency of the element to lose or gain an electron.
