here are the solutions to the questions:* 13) The electronic configuration is 1s^2 2s^2 2p^6 3s^2 3p^6 3d^5 4s^2. Step 1: Determine the total number of electrons. Total electrons = 2+2+6+2+6+5+2 = 25. This element is Manganese (Mn). Step 2: Determine the maximum oxidation number. Manganese is a transition metal in Group 7. Its maximum oxidation number is typically achieved when all its valence electrons (from the 4s and 3d orbitals) are involved in bonding. Number of ✂️ _That answer was long and got cut off.
