To determine the number of electrons in an atom, we need to know the electronic configuration of the atom. The electronic configuration is a representation of the arrangement of electrons in different energy levels or shells.
In this case, we are given that both the K and L shells of the atom are full.
The K shell can hold a maximum of 2 electrons, and the L shell can hold a maximum of 8 electrons.
Since both shells are full, we can determine the number of electrons in the atom by adding the maximum number of electrons in each shell:
- K shell: 2 electrons
- L shell: 8 electrons
Therefore, the total number of electrons in the atom is 2 + 8 = 10.
Hence, the correct answer is option B: 10.
