The correct question is: How many moles are in 
atoms of boron.
Answer: There are 145 moles present in atoms of boron.
Explanation:
According to the mole concept, there are 
atoms present in one mole of every substance.
Hence, number of moles present in atoms is calculated as follows.
Thus, we can conclude that there are 145 moles present in atoms of boron.
Answer:
CaCl₂(s) ⟶ Ca²⁺(aq) + 2Cl⁻(aq)
Explanation:
When the calcium chloride dissolves. the calcium and chloride ions leave the surface of the solid and go into solution as hydrated ions.

Explanation:
These are called quantum numbers: there are 4, but the first three are mainly used, only in orbital notation will you use all four.
The first is the electron's energy level or "shell", used as n. (Principle QN)
The second relates to the shape of the orbital and is used as l, when n and l are put together it defines the sublevel or subshell. (Angular Momentum QN)
The third one relates to the orientation of the electrons in that sublevel used as m(sub)l. (Magnetic QN)
The fourth one relates to the spin states of the electron, since they spin opposite directions, used as m(sub)s. (Electron Spin QN)
