Barium.
Element family number 2, known as the alkaline earth metals, includes the elements beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra). These elements share similar chemical properties, such as forming 2+ cations and being reactive.
Radium is a member of the group 2 (alkaline earth metals) of the periodic table of Mendeleev; the other members are beryllium, calcium, magnesium, strontium, barium
Group 2 (alkaline earth metals): beryllium, calcium, magnesium, strontium, barium, radium.
Element M is calcium. It reacts with chlorine to form calcium chloride (CaCl2). Calcium is more reactive than magnesium and smaller than barium on the periodic table.
Barium.
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.
Beryllium, Magnesium, Calcium, Strontium, Barium and Radium.
Beryllium, Magnesium, Calcium, Strontium, Barium, Radium

Calcium is a member of group 2, whose elements are beryllium, magnesium, calcium, strontium, barium and the radioactive radium.
Beryllium, Magnesium, Calcium, Strontium, Barium, and Radium all have an oxidation state of plus 2.
