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.
What else can I help you with?
Is Ca or Sc more reactive in science?
Calcium (Ca) is more reactive than scandium (Sc) in science. This is because calcium is a more electropositive element compared to scandium, making it more likely to undergo chemical reactions with other elements.
Is calcium more reactive than aluminium?
yes. because calcium is almost never found in nature due to its high reactivity with water, but we can find copper metal in nature.
What would be most reactive toward fluorine K Ca Sc Co?
Fluorine would be most reactive towards potassium (K) because potassium is a highly reactive alkali metal that readily donates its outer electron to form a stable ion. scandium (Sc), cobalt (Co), and calcium (Ca) are less reactive than potassium and would not react as vigorously with fluorine.
Which of the following elements has the lowest electronegativity ba ca mg sr?
Mg (magnesium) has the lowest electronegativity among Ba, Ca, Mg, and Sr.
What is the balanced equation of calcium and zinc nitrate?
Zinc nitrate is an amphoteric compound, hence it will react with the reactive metal (calcium). Zn(NO3)2 + Ca --> Ca(NO3)2 + Zn The above is a displacement reaction, where the more reactive calcium displaces the less reactive zinc.
Is Ca or Sc more reactive in science?
Calcium (Ca) is more reactive than scandium (Sc) in science. This is because calcium is a more electropositive element compared to scandium, making it more likely to undergo chemical reactions with other elements.
Using the periodic table choose the more reactive metal. Ca or Ra?
Radium (Ra) is more reactive than calcium (Ca). Both are alkali earth metals, but as you move down the group in the periodic table, reactivity increases due to the larger atomic size and the decrease in ionization energy. Therefore, radium, being lower in the group, is more reactive than calcium.
Is calcium more reactive than aluminium?
yes. because calcium is almost never found in nature due to its high reactivity with water, but we can find copper metal in nature.
What would be most reactive toward fluorine K Ca Sc Co?
Fluorine would be most reactive towards potassium (K) because potassium is a highly reactive alkali metal that readily donates its outer electron to form a stable ion. scandium (Sc), cobalt (Co), and calcium (Ca) are less reactive than potassium and would not react as vigorously with fluorine.
Which of the following elements has the lowest electronegativity ba ca mg sr?
Mg (magnesium) has the lowest electronegativity among Ba, Ca, Mg, and Sr.
Which is more reactive Mg or Ca Why?
Calcium is more reactive. In the periodic table, Calcium is directly below Magnesium, which means that a calcium atom is larger than a magnesium atom. This means that the electrostatic attraction between the valence electrons of calcium and the nucleus is weaker than in magnesium(larger distance, smaller force). So, the valence electrons of calcium can easily be lost to form Ca2+ , which translates to Calcium being the more reactive metal.
What is the balanced equation of calcium and zinc nitrate?
Zinc nitrate is an amphoteric compound, hence it will react with the reactive metal (calcium). Zn(NO3)2 + Ca --> Ca(NO3)2 + Zn The above is a displacement reaction, where the more reactive calcium displaces the less reactive zinc.
What element reacts with H2O to produce H2?
All metals more reactive than Zn: Al, Mg, Na, Ca, Ba, K, Li
What element is most active out of Be Mg Sr Ca?
Barium (Ba) is the most electropositive element. In general, electropositivity (reverse of electronegativity) decreases across the rows of the periodic table and increases down the columns.
Are the elements ba and ca metals or nonmetals?
Barium (Ba) and calcium (Ca) are both metals, belonging to alkaline earth metals or group 2.
Which is more chemically active Ca or Rn?
Ca (calcium) is more chemically active than Rn (radon). Calcium is a reactive alkaline earth metal that readily forms compounds with other elements, while radon is a noble gas known for being chemically inert due to its full valence shell.
Which is more reactive na or li why?
Sodium (Na) is more reactive than lithium (Li) because sodium has a smaller atomic size and lower ionization energy, making it easier for sodium to lose an electron and form a more stable configuration compared to lithium. This results in sodium being more prone to reacting with other elements and compounds.
