Before this question I never really thought about it, but if I had to choose it would be Calcium. Because I like the letters, the 2+, and it plays an important role in the signal transmission between neurons in the brain.
I have a favourite group on the periodic table, the transition metals. Those are the ones in the square in the middle. I really like them because of the trends in their chemical behaviour, also when you spray them into a flame they make awesome colours.
