Perhaps the electronic configuration of Chromium? Ar for argon, argon has 18 electrons. Electronic configuration of argon can be written as 1s22s22p63s23p6. Electronic configuration of chromium is 1s22s22p63s23p63d54s1. As you can see you can just replace that long chain of figures in front of 3d54s1 with just Ar. Hence, [Ar]3d54s1.
How many tornadoes have hit Fayetteville, AR?

moles= mass/Mr so 525 divided by the Mr of ZnCl-2 Mr of ZnCl-2= (Ar of Zn= 65.37)+(2 x Ar of Cl= 2 x 35.5= 71) = 136.37 moles= 525/136.37 = 3.85 moles to 3 significant figures. (in grams) divide the answer by 1000 to get mg so 3.85/1000= 0.00385 moles
