Question

Answer the following about alkaline earth metals :
1 Name the member of the alkaline earth family.
To which group do they belong?
TI Which member is radioactive in nature?
iv)
Which member is the least reactive ?​

Answer 1

Answer:

1.The members of the alkaline earth metals include: beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba) and radium (Ra). As with all families, these elements share traits. While not as reactive as the alkali metals, this family knows how to make bonds very easily.

The radioactive nuclei, or radionuclides, found naturally on Earth can be grouped into three series–headed by uranium-238, uranium-235, and thorium-232–plus several isolated beta-particle emitting nuclei, most prominently potassium-40 and rubidium-87. Average abundances of these nuclides are listed in Table 15-1.

The member least reactive is LITHIUM
