What else can I help you with?
Is the electronegativiy of barium larger or smaller than that of strontium?
The electronegativity of barium is less than that of strontium.
What would react more vigorously with water strontium or calcium?
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).
Why is the first ionisation energy of strontium larger than the first ionisation energy of rubidium?
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.
What elements have a smaller atomic radius than strontium?
Ca, Mg, Be, Fr, Cs, Rb, K, Na, Li, H
What is a balance molecular equation for strontium hydroxide and lithium phosphate in an aqueous medium?
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).
Is calcium strontium beryllium or magnesium more reactive?
Among calcium, strontium, beryllium, and magnesium, strontium is the most reactive. Reactivity generally increases down a group in the periodic table, and strontium is below calcium. Beryllium, being a group 2 alkaline earth metal, is less reactive than the other three. Therefore, in order of increasing reactivity, it would be beryllium, magnesium, calcium, and then strontium.
Which is more electronegative Sr or Be?
Sulfur is more electronegative than beryllium.
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 alkali earth metal is the most reactive Be or Sr?
Be (beryllium) is more reactive than Sr (strontium) among the alkali earth metals. Beryllium has a higher reactivity due to its small atomic size and high electronegativity, making it more likely to form bonds with other elements.
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.
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.
Is beryllium reactive and why is it reactive?
Yes, beryllium is reactive due to its tendency to form bonds with other elements to achieve a more stable electron configuration. It readily reacts with oxygen in the air to form beryllium oxide, which is why it is often found in nature as compounds rather than in its pure form.
Is beryllium more reactive than magnesium?
No, beryllium is not more reactive than magnesium. In fact, beryllium is less reactive due to its smaller atomic size and higher ionization energy, which makes it more stable and less likely to lose its outer electrons compared to magnesium. While both elements belong to Group 2 of the periodic table, magnesium's reactivity increases as you move down the group.
Which element would be most reactive be sr or ba?
Barium (Ba) would be more reactive than strontium (Sr) because barium is located further down the Group 2 elements in the periodic table. As you move down the Group, the reactivity of the elements tends to increase due to the larger atomic size and lower ionization energy, making barium more reactive than strontium.
Which is more reactive barium magnesium or beryllium?
Barium is more reactive than magnesium, and beryllium is less reactive than both. Reactivity generally increases as you move down a group on the periodic table, so barium is more reactive than magnesium due to its position in the same group.
Why Ba is more reactive than Ca?
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.
Why is lithium more reactive then beryllium?
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.
