Ca 2+ Electron Configuration (Calcium Ion) - YouTube

WebbOkay in ionic compounds metals donate electrons to non-metals, so the outer two electrons of calcium have been donated to the OH's, hence they have 1 blue electron and a negative charge each. This leaves Ca with a 2+ charge and a full outer shell. WebbIn similar preparations from human atria at 30 degrees C and 37 degrees, Ca paradox was obtained similarly as in other homoiotherms. In homoiotherms, lowered temperature (below 30 degrees C) has a protective effect. Viper myocardium did not display Ca paradox at 12, 22 or 32 degrees C, whereas human myocardium displayed Ca paradox even at 30 C.
