Type in the correct values to correctly represent the valence electron configuration af magnesium: \( A 5^{8} \) \( \mathrm{~A}=\square \) \( \mathrm{B}=\square \) EaIRY

The valence electron configuration of magnesium (Mg) can be represented as follows: Magnesium has an atomic number of 12, which means it has 12 electrons. The electron configuration for magnesium is: 1s² 2s² 2p⁶ 3s² The valence electrons are the electrons in the outermost shell, which for magnesium are the two electrons in the 3s subshell. In the notation \( A^B \): - \( A \) represents the number of valence electrons. - \( B \) represents the total number of electrons in the outermost shell. For magnesium: - The number of valence electrons (A) is 2 (from the 3s²). - The total number of electrons in the outermost shell (B) is also 2 (since only the 3s subshell is occupied). Thus, the correct values are: \( A = 2 \) \( B = 2 \) So, the completed representation is: \( A = 2 \) \( B = 2 \) Therefore, the answer is: \( A = 2 \) \( B = 2 \)
