Yes that is right I look it up thanks for the points
The basic requirement while writing the electronic configuration of an element (atom) is its atomic number.
Explanation:
- The electronic configuration of an element is the distribution of its electrons in different energy levels around the atomic nucleus.
- It only requires an atomic number of an element to write its electronic configuration.
- The atomic number is equal to the number of protons in an atom and that is equal to the number of electrons.
- And the filling of electrons is done according to the Aufbau principle, the electrons will be first filled in the atomic orbitals with lower orbital energy before filling the atomic orbital with higher energy.
- The sequence of the atomic orbitals from lower energy to higher energy is:
[tex]1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, 4f, 5d, 6p, 7s, 5f, 6d...[/tex]
For example:
The atomic number of gallium is 31, its electronic configuration will be:
[tex][Ga]=1s^2 2s^2 2p^63s^2 3p^6 4s^2 3d^{10} 4p^1[/tex]
