40 mg bohr diagram
Bohr’s diagram of Magnesium has three electron shells (K, L, and M), the inner shell is K-shell and the outermost shell is M-shell. Hence, the electrons found in the M-shell of the Magnesium atom are its valence electrons because it is the outermost shell that also called the valence shell. Symbol: Mg Atomic Number: 12 Atomic Mass: 24.305 amu Melting Point: 650.0 °C (923.15 K, 1202.0 °F) Boiling Point: 1107.0 °C (1380.15 K, 2024.6 °F) Number of Protons/Electrons: 12 Number of Neutrons: 12 Classification: Alkaline Earth Crystal Structure: Hexagonal Density @ 293 K: 1.738 g/cm 3 Color: grayish Atomic Structure 13.12.2002 · The density of α-iron is 7.86 g/cc. At 910°C it changes to γ-iron, which is face-centered cubic and somewhat softer. At 1535°C iron melts, and boils at 3000°C. For more information on iron structures and the iron-carbon phase diagram, see Phase Rules!. Cobalt melts at 1480°C, nickel at 1455°C. Mg bohr diagram
