Calcium and strontium are both alkaline earth metals found in Group 2 of the Periodic Table. They share similar chemical properties, such as forming +2 oxidation states and reacting with water to produce hydroxides and hydrogen gas. Additionally, both elements have relatively low densities and melting points compared to other metals, and they are commonly used in various applications, including in the production of alloys and in fireworks.
What else can I help you with?
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.
Why does strontium replace calcium in human bones?
Strontium is chemically very similar to Calcium. The human body will readily use Strontium as bone-making material, but Strontium does not satisfy the other uses the human body has for Calcium e.g. regulating calcium content in blood, etc.
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.
Is strontium larger than a calcium atom?
Yes, strontium is larger than a calcium atom. Strontium has a higher atomic number (38) compared to calcium (20), which means it has more electron shells. This additional shell increases the size of the strontium atom, resulting in a larger atomic radius than that of calcium.
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.
What is the equation for calcium and strontium with oxygen?
The chemical formulas for calcium oxide and strontium oxide are CaO and SrO, respectively. These compounds are formed when calcium or strontium react with oxygen.
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 element on the periodic table is directly below calcium?
The element directly below calcium on the periodic table is strontium. Strontium has similar chemical properties to calcium because they belong to the same group, known as alkaline earth metals.
What do barium calcium chlorine magnesium potassium sodium and strontium have in common?
All discovered by Humphrey Davy through electrolysis
Difference between calcium carbonate and strontium carbonate?
Calcium carbonate is a chemical compound commonly found in rocks, pearls, and eggshells, while strontium carbonate is a similar compound that contains strontium instead of calcium. They both have similar chemical properties but strontium carbonate is slightly more soluble in water than calcium carbonate. Strontium carbonate is often used in fireworks and ceramic glazes, while calcium carbonate is commonly used as a dietary supplement and in construction materials.
What has greater atomic size calcium or strontium?
Strontium has a greater atomic size than calcium because strontium has more electrons and energy levels in its electron cloud, resulting in a larger atomic radius.
Why is it easier for strontium to lose valence electrons than calcium?
Strontium is larger in size compared to calcium due to more electron shells, making it easier for strontium to lose valence electrons farther from the nucleus. This results in weaker attraction between the valence electrons and the nucleus, leading to easier electron loss in strontium compared to calcium.
does calcium and strontium have something common?
Yes, calcium and strontium share several similarities as they both belong to the alkaline earth metals group in the periodic table. They have similar chemical properties, including reactivity and the ability to form similar compounds, such as carbonates and sulfates. Additionally, both elements are essential for biological processes; calcium is crucial for bone health, while strontium is sometimes used in medical applications related to bone health.
