because rubidium has one valence electron while strontium has two.
What else can I help you with?
What happens to the radii of rubidium and strontium?
The radius of strontium is smaller than the radius of rubidium.
Is beryllium more reactive than strontium?
No, strontium is more reactive than beryllium.
Is sodium more reactive than strontium?
Yes, sodium is generally considered more reactive than strontium. Sodium, an alkali metal, reacts vigorously with water and air, while strontium, an alkaline earth metal, is less reactive than sodium. The reactivity of alkali metals increases down the group, but sodium is higher up than strontium in the reactivity series, making it more reactive overall.
Is calcium more reactive than strontium?
No, strontium is more reactive than calcium. This is because strontium is located below calcium in the periodic table and thus has a larger atomic size, making it easier for strontium to lose its outermost electron and react with other elements.
What is more reactive rubidium or krypton?
Rubidium is more reactive than krypton. Rubidium is an alkali metal and reacts vigorously with water, while krypton is a noble gas and is inert under normal conditions.
Does rubidium and strontium ion have the same electronic configuration?
NO!!!! Each element has it own ground state electron configuration. Rubidium is [Kr] 5s1 Strontium is [Kr] 5s2. Notice that strontium has one MORE electron than Rubidium. The symbol [Kr] is shorthand for the full electron configuration of krypton.
Why is rubidium more reactive than sodium?
Rubidium is more reactive than sodium because rubidium has a larger atomic radius and fewer electron shells, making it easier for rubidium to lose an electron and form a positive ion. This tendency to lose an electron increases its reactivity compared to sodium.
What Fireworks contain metals that are brightly colored when burned .they are less reactive than some other metals .which metal is one example?
Fireworks that contain metals like strontium, barium, copper, and sodium can produce bright colors when burned. Strontium is an example of a metal used in fireworks that is less reactive than some other metals.
Calcium magnesium and strontium are near each other on the periodic table and have some characteristics in common but they differ in chemical reactivity. Which lists these metals in order from most re?
The order of calcium, magnesium, and strontium from most reactive to least reactive is strontium, calcium, and then magnesium. Strontium is more reactive than calcium due to its lower ionization energy and larger atomic radius, which make it easier to lose electrons. Magnesium, while still reactive, is less so compared to both strontium and calcium because of its higher ionization energy.
Why sodium is more reactive than potassium?
The atomic radius of potassium is greater than that of sodium. Therefore, the single valence electron that exists for all alkali metals is located farther from the nucleus for potassium than sodium. This results in less energy required to remove that valence electron from potassium than from sodium, leading to increased reactivity. Note that this trend continues as you move down Group I on the Periodic Table, meaning that Rubidium is more reactive than Potassium and Cesium is more reactive than Rubidium.
Is the electronegativiy of barium larger or smaller than that of strontium?
The electronegativity of barium is less than that of strontium.
What element is more active Sr or Ag?
Sr (strontium) is considerably more reactive than Ag (silver). In fact, Strontium is so reactive that it must be stored in mineral oil to prevent its reaction with the oxygen in the air. Strontium also reacts with water.
