The alkaline earth metals and especially barium.
Polonium and radium are radioactive chemical elements but they have not the same properties.
Radium is in the alkaline earth metals.
Calcium and radium are in the same group of the periodic table of Mendeleev (group 2, alkaline earth metals); consequently calcium and radium has similar chemical properties and can be interchangeable in some situations.
There are six metals in group two of the periodic table. These metals are beryllium, magnesium, calcium, strontium, barium, and radium. They are known as the alkaline earth metals and have similar chemical properties.
Yes. Radium is actually considered an alkaline earth metal. Its colour is nearly pure white, but when exposed to air, it turns black. Radium is also extremely radioactive. A link is provided to the Wikipedia article on radium.
Radium is a non-magnetic metal.
See the link below for detailed informations about radium.
Elements in the same family-assuming family means classifications such as non-metals, metals-have similar properties.
no
Radium is in the group 2 (alkaline earth metals) of the periodic table of Mendeleev.
Polonium and radium are natural chemical elements, metals, solid, very radioactive.
Are they in the same row
