Respuesta:
A neutral atom has the same number of protons (positive charges) and electrons (negative charges) such that the overall charge is zero (ergoneutral). Neutrons have zero charges. We use the proton number as the atomic number because the number of protons is non-changing.
Explicación:
The number of electrons in the first shell is 2. The maximum number of electrons in a shell is
2 n i.e. for n = 1 , giving 2 1 = 2 ′ e .
