No, strontium is more reactive than beryllium.
The electronegativity of barium is less than that of strontium.
Strontium. They both have two electrons in their outermost energy level, however since the electrons are farther from the nucleus in Strontium than in Calcium, Strontium is more readily able to shed these two electrons to achieve a more stable state with it's outermost energy level being complete (with 8 electrons).
Because, as we know that when we go across the period of the periodic table, the number of shells remain the same but the number of electrons and protons increases. So, Rb having its atomic number as 37 and Sr as 38, Strontium has got more nuclear charge as well as more electrons. As a result the first ionisation energy required to remove one electron is more in Strontium than Rubidium.

Because strontium sulfate is much less soluble in water than strontium chloride, sodium chloride, or sodium sulfate, this reaction is: Na2SO4 (aq) + SrCl2 (aq) => 2 NaCl (aq) + SrSO4 (s).
No, strontium is more reactive than calcium.
Sulfur is more electronegative than beryllium.
strontium is more reactive than calcium because it is more electropositive. valance electrons of strontium are farther away from the nucleus of strontiium atom than the valance electrons of calcium from nucleus of calcium atom. so the force exerted by the nucleus on the valence electron of strontium is lesser than that exerted by calcium. so the strontium atom can loose its valance electrons more easily. therefore strontium is more electropositive and more reactive than calcium.
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.
Down a group the reactivity increases. So, barium (Ba) is more reactive than strontium (Sr).
because rubidium has one valence electron while strontium has two.
No, beryllium is less reactive than carbon. Beryllium is a group 2 element and has a relatively low reactivity, while carbon is a group 14 element and can form a wide variety of compounds due to its ability to bond with other elements.
I think lithium should be more reactive as it has only 1 valance electron wheres Boron has 3 valance electrons. The electro positivity(tendency to lose electrons) of Lithium is greater then Boron, therefore more reactive.
Sulfur is more electronegative than beryllium. The electronegativity of sulfur is 2.58, and the electronegativity of beryllium is 1.57.
sodium is more reactive than magnesium!
Lithium is wayy more reactive... like, duh? An elements reactivity depends on its ionisation energy (the amount of energy required to remove one electron from the atom) and if you look at a periodic table the ionisation energy is known to increase across the table and decrease down it. Berylium is further across the table than lithium so you'd expect it to have a lower ionisation energy and be less reactive. This is because beryllium (atomic number 4) has 4 protons, which cause a positive charge and subsequent attraction of electrons, while lithium has the atomic number 3 and therefore only has 3 protons to attract its electrons. Lithium is a Group I alkali metal, while Beryllium is a Group II alkaline earth metal. Group I Alkali metals are generally more reactive as they only need to lose one electron to have a complete outer shell.
Beryllium and Lithium have many differences. Lithium reacts readily with water, where Beryllium does not. Lithium has a fairly low melting point, and Beryllium has a high melting point. Beryllium is highly toxic, and Lithium is fairly nontoxic. Both are metals, and have metallic appearance and conduct electricity but Beryllium more brittle than Lithium is.
