The diagram shows the electron configuration of an atom of an element for the electrons in the s and p orbitals. A shaded circle is shown. There are two concentric circles around this shaded circle. The inner concentric circle has two dark shaded dots. The outer concentric circle has two dark shaded dots in the corresponding position to the inner concentric circle. The outer concentric circle also has three light shaded dots one on its left boundary, one on the right boundary and the third on the lower boundary. What is the group number of the element in the periodic table? 1 2 13 15

Ican determine the molar mass of an element by looking on the under the atomic mass for the element. for example the molar mass of phosphorus is 30.974 grams/mole. avogadro’s number tells me the amount of representative particles in 1 mole of any substance. this means 12.011 gram sample of carbon and a 32.0 gram sample of sulfur have the same number of atoms.
