The Periodic Table

by | Apr 2, 2022 | Exam

The periodic table is a useful tool for chemists and can also provide useful information during your chemistry exam.

Information on electronic configuration

Group number (column) is the number of electrons in the outer shell of an atom. Period number (row) is the number of electron shells that an atom has. So, for example, boron is in group 3 and period 2 so has 3 electrons in its outer shell and has 2 shells.
