A piece of metal has a mass of 200 g and a volume of 2 cm3. What is its specific gravity?

Some patterns of electron configuration are listed below. In each case, G stands for a noble-gas core and n, m, or o stand for integer numbers like 1, 2, 3 and so on. Note: assume G is lighter than Rn.Think about the chemical elements made of atoms with an electron configuration that matches each pattern. In what block or blocks of the Periodic Table would these elements lie? Would they be metals, nonmetals, metalloids, some of each? Use your answers to these questions to complete the table.electron configurationof atoms location of elements(check all that apply)blocks metals or nonmetals?Gns2np5 metalsspnonmetalsdfmetalloidsGns2 metalsspnonmetalsdfmetalloidsGns2md10np4 metalsspnonmetalsdfmetalloids
