Electronic Formulas of Atoms with Atomic Numbers 11 and 14

The electronic formulas of atoms can be represented using the notation that indicates the distribution of electrons in the atom's energy levels. Here are the electronic formulas for atoms with atomic numbers 11 and 14:

1. Atom with Atomic Number 11: - The atom with atomic number 11 corresponds to the element sodium (Na). - The electronic formula for sodium is 1s^2 2s^2 2p^6 3s^1. - This notation indicates that sodium has 11 electrons distributed in different energy levels. - The first energy level (n=1) has 2 electrons (1s^2). - The second energy level (n=2) has 8 electrons (2s^2 2p^6). - The third energy level (n=3) has 1 electron (3s^1).

2. Atom with Atomic Number 14: - The atom with atomic number 14 corresponds to the element silicon (Si). - The electronic formula for silicon is 1s^2 2s^2 2p^6 3s^2 3p^2. - This notation indicates that silicon has 14 electrons distributed in different energy levels. - The first energy level (n=1) has 2 electrons (1s^2). - The second energy level (n=2) has 8 electrons (2s^2 2p^6). - The third energy level (n=3) has 4 electrons (3s^2 3p^2).

Please note that the electronic formulas provided are based on the atomic structure of the elements sodium (Na) and silicon (Si) and their respective atomic numbers of 11 and 14.
