Bohr-Rutherford diagrams depict the arrangement of electrons in an atom, indicating the number of electrons in each electron shell.
Sodium has 11 electrons. The electron configuration is 2-8-1, meaning it has two electrons in the first shell, eight in the second, and one in the third.
Bohr-Rutherford Diagram for Sodium: Represent the nucleus and electron shells, with two electrons in the innermost shell, eight in the second, and one in the outermost third shell. Sodium readily loses its outermost electron to achieve a stable, noble gas electron configuration (similar to neon). After losing an electron, it becomes positively charged.
Nitrogen has 7 electrons. The electron configuration is 2-5, with two electrons in the first shell and five in the second. Bohr-Rutherford Diagram for Nitrogen represent the nucleus and electron shells, with two electrons in the first shell and five in the outermost second shell.
