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.
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.
The alkaline earth metals are beryllium, magnesium, calcium, strontium, barium, and radium. These elements are all metallic in nature and share similar chemical properties, including the ability to react vigorously with water. They are located in Group 2 of the periodic table.
Magnesium belongs to group 2 (alkaline earth metals) in the periodic table. Elements in the same group as magnesium include beryllium, calcium, strontium, barium, and radium. They all share similar chemical properties due to having the same number of electrons in their outermost shell.
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.
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
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.
Barium.
Beryllium (Be) apexvs
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.
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.
