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.
Magnesium is an alkali earth metal. Beryllium and calcium are also alkali earth metals.
Calcium is in group 2 of the periodic table. The group consists of beryllium, magnesium, calcium strontium, barium and radium. Calcium is in period 4.
Magnesium has a lower melting and boiling point than calcium, strontium, and other members below it in the group because it has a smaller atomic size, lower nuclear charge, and weaker metallic bonding. These factors result in weaker forces of attraction between the magnesium atoms, making it easier to overcome them and melt or boil the metal.
Magnesium metal is extracted from dolomite, which is a mineral composed of calcium magnesium carbonate. The process typically involves thermal reduction of dolomite to produce magnesium metal and calcium oxide.
Six elements are there. And they are: beryllium, magnesium, calcium, strontium, barium, radium
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.
Calcium is a member of group 2, whose elements are beryllium, magnesium, calcium, strontium, barium and the radioactive radium.

Examples: sodium, potassium, calcium, magnesium etc.
Calcium is in group 2 of the periodic table. The group consists of beryllium, magnesium, calcium strontium, barium and radium. Calcium is in period 4.
This group contains beryllium, magnesium, calcium, strontium, barium and radium. They are all alkali earth metals.
Another element in group 2 of the periodic table is strontium. It has an atomic number of 38 and is a soft, silvery metal that is similar in properties to calcium. Strontium is commonly used in fireworks and in the production of cathode ray tubes.
There are six elements in the alkaline earth metal group on the periodic table: beryllium, magnesium, calcium, strontium, barium, and radium.
The symbol that represents an alkaline earth metal is Be (beryllium), Mg (magnesium), Ca (calcium), Sr (strontium), Ba (barium), or Ra (radium).
