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
The answer is not determinable both because scientists have not determined the exact volume of the universe and because the universe is always expanding.
eight
2
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)
