Answer is: a. Rubidium (Rb) is more reactive than strontium (Sr) because strontium atoms must lose more electrons.
The ionization energy (Ei) is the minimum amount of energy required to remove the valence electron, when element lose electrons, oxidation number of element grows (oxidation process).
Alkaline metals (group 1), in this example rubidium, have lowest ionizations energy and easy remove valence electrons (one electron), they are most reactive metals.
Earth alkaline metals (group 2), in this example strontium, have higher ionization energy than alkaline metals, because they have two valence electrons, they are less reactive.
Rubidium electron configuration: ₃₇Rb 1s²2s²2p⁶3s²3p⁶3d¹⁰4s²4p⁶5s¹; one valence electron is 5s¹ orbital.
Strontium electron configuration: ₃₈Sr 1s²2s²2p⁶3s²3p⁶3d¹⁰4s²4p⁶5s²; two valence electrons is 5s² orbital.

what wheres the answer???
Answer:
I would say that a sauce is a mixture, only because everything that makes up a sauce is all mixed together and turned into one thing, it isn't all separate.
Answer:
Compounds
Explanation:
Substances in which atoms of two or more elements are chemically combined are called compounds.
A compound is a substance formed when two or more elements are chemically joined.
Well, trees are over 20 feet tall and have trunks that are like in 2 inches and 4.5 feet about the ground. Bushes are smaller than the trees and usually have smaller, woody, bark leafs.
Well im gonna say it would be the same,but not in size.
Hope this helps
