Beryllium (Be) - 9.012
The element in the periodic table that has 4 electrons in its outer energy shell and the lowest atomic mass in its family is carbon (C). Carbon belongs to Group 14 of the periodic table, which is also known as the carbon family. With an atomic number of 6, it has the lowest atomic mass among its group, which includes elements like silicon and germanium.
The lightest element in the group 2 of the periodic table of elements is calcium - with a density of 1,55 g/cm3.
Z is atomic number, so from the periodic table, you can see that this is the element krypton, Kr. You can also see that this element is in Group 18 (VIIIA), which is the noble gases group.
Yes. Bromine is an element. Its symbol is Br. It is placed in Group-17 of periodic table.
