5s orbital
Rubidium has one valence electron in the 5s orbital.
5s
in 5s it is filled but in 4d or 4s its half
3s has a principle quantum number of n=3 5s has a principle quantum number of n=5
995 Miles = 1,601.3km
995 grams = 2.19359951 pounds
995 miles=1,601.29728 kilometers
21 5s
995 multiplied by 995 is 990,025
995
Rubidium has one 5s electron.
Since there are 1000 grams in each kilogram, 995 grams is the same as 0.995 kilograms.
The positive integer factors of 995 are: 1, 5, 199, 995
199 of course !
1.5% of 995= 1.5% * 995= 0.015 * 995= 14.925
