because they are all alkaline earth metals and occur naturally in nature.
Calcium has similar physical and chemical properties to magnesium and strontium. They all belong to the same group of the periodic table, which means they have similar reactivity and characteristics.
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.
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.
Barium.
Radium is the least reactive among calcium, magnesium, strontium, and barium. Radium is a highly radioactive metal that readily reacts with other elements, but it is less reactive compared to the other listed elements.
Strontium and barium are two elements that can replace calcium in some chemical reactions or compounds due to their similar chemical properties.
Calcium has similar physical and chemical properties to magnesium and strontium. They all belong to the same group of the periodic table, which means they have similar reactivity and characteristics.

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.
The chemical properties of calcium are most similar to the chemical properties of magnesium and strontium, as they all belong to the same group in the periodic table (Group 2 or alkaline earth metals). These elements share similar reactivity, ionization tendencies, and ability to form ionic compounds with similar characteristics.
Beryllium, magnesium, calcium, strontium, barium, and radium.
Six elements are there. And they are: beryllium, magnesium, calcium, strontium, barium, radium
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.
Group 2 elements or alkaline earth metals are beryllium, magnesium, calcium, strontium, barium and radium
Beryllium, Magnesium, Calcium, Strontium, Barium, and Radium all have an oxidation state of plus 2.
Calcium, strontium, beryllium, and barium are elements that are similar to magnesium. They all belong to Group 2 of the periodic table and share similar chemical properties and reactivity.
Strontium and barium are two elements that have similar properties to calcium because they belong to the same group in the periodic table (group 2 alkaline earth metals) and exhibit similar chemical behavior due to having the same number of valence electrons.
