3 rhombuses will fit into one Hexagon...so it would be 20x3
it is 1736
72
A meter stick is 100cm, therefore 20 pencils would fit on a meter stick.
a number .
one
There can be 10 electrons in the n=2 shell. Two can fit in the 1s orbital, two can fit in the 2s orbital, and six can fit in the 2p orbital.
The second electron shell can hold a maximum of 8 electrons.
Inversely, 1836 electrons fit in a proton !
The number of atoms in the universe is estimated at 1078 to 1082. So the number of molecules would be smaller than this, obviously. Reference: http://www.universetoday.com/36302/atoms-in-the-universe/
Two electrons can fit in the first shell
eight
2
The answer is not determinable both because scientists have not determined the exact volume of the universe and because the universe is always expanding.
The first orbital shell can hold a maximum of 2 electrons.
Well, there is a formula to figure out how many combinations of universes there would be that fit in the size of the observable universe. The formula is spacetimeatoms*elements and by working this out you would get 10 to the 225 power, factorial.
8 (2s2, 2p6)
