What is the color of beryllium?
Beryllium is a silvery-white metal. Why is Group 2 called alkaline earth metals?
Beryllium, magnesium, calcium, strontium, barium and radium are the elements in Group 2. For two reasons, these elements are referred to as Alkaline Earth metals, Their oxides remain in the crust of the earth and are very heat-stable. The elements of Group 2 of the periodic table are alkaline earth metals. How do we find atomic mass?
For any given isotope, the sum of the numbers of protons and neutrons in the nucleus is called the mass number. This is because each proton and each neutron weigh one atomic mass unit (amu). By adding together the number of protons and neutrons and multiplying by 1 amu, you can calculate the mass of the atom. What are the Group 1 elements called?
