Avogadro's number represents the number of units in one mole of any substance. This has the value of 6.022 x 10^23 units / mole. This number can be used to convert the number of atoms or molecules into number of moles. We do as follows:
10 mol NH3 ( 6.022 x 10^23 molecules / 1 mol ) = 6.022x10^24 molecules NH3
The number of protons in an atoms determines the atoms identity. Electrons determine the electrical charge.
Explanation:
Atomic radius decreases from left to right in a period.
Therefore Calcium would have a smaller atomic size.
Hi Sara
I would say it is an amorphous solid.
Because it's gradually loses shape.
I hope that's help:)
