Elements with no stable isotopes include technetium (element 43) and promethium (element 61) and all elements heavier than lead (elements 83 and higher). Bismuth, element 83, is virtually stable with an extremely long half life of 1.9 x 1019 years.
Yes, americium is a radioactive metal. This element has no stable isotopes.
No, cesium is an alkali metal. Metals do not react with one another. Cesium reacts with nonmetals and acids to form salts.
No- it is an alkaline earth metal.
The alkali metal in period 2 is lithium (Li).
Calcium chloride contains an alkali earth metal (calcium, a group 2 element) and a halogen (chlorine). There is no alkali metal. Alkali metals are group 1 elements.
Yes, americium is a radioactive metal. This element has no stable isotopes.
Ba and Cs
The alkali metal, sodium, is an element.
Tc stands for the element technetium. Technetium is a silvery-gray metal and it is the first element on the periodic table that does not have any stable isotopes.
Lithium is an alkali metal.
No, cesium is an alkali metal. Metals do not react with one another. Cesium reacts with nonmetals and acids to form salts.
No...
No, CS is not an alkali metal. It is a chemical element known as cesium, which belongs to the alkali metal group on the periodic table.
Hydrogen is in group 1 but is not an alkali metal.
No- it is an alkaline earth metal.
element, specifically an alkali earth metal.
Alkali is a basic, ionic salt of an alkali metal or alkaline earth metal element. Thus, the chemical composition of an alkali is: alkali metal,hydrogen,oxygen,carbon.
