Explanation / Answer

3. The principal quantum number decribes the size and energy of an electron.
B. principal quantum number.

44. TiCo3 titanium(II) carbonate
C. titanium(II) carbonate
45.S = 16   1s^2 2s^2 2p^6 3s^2 3p^4
A. 10
46. 2.atm
   1 atm = 760torr
2 atm = 2*760 torr = 1520 torr
A. 1520 torr
47.Si = 14   1s^2 2s^2 2p^6 3s^2 3p^2      3p- orbital two unpaired electrons

B. 2
