Calcium chloride (CaCl2) is a salt which dissociates when dissolved in water. Assuming that the dissociation is complete (100 %), then the half reaction for this would be:

<span>CaCl2 ---> Ca2+  +  2 Cl-</span>

We can see that in 1 mole of CaCl2 salt, 1 mole of Ca2+ ion and 2 moles of Cl- ion is created. Therefore there are 3 moles of ion per 1 mole of CaCl2. Using this ratio, the total number of moles of ions in the solution is:

Total number of ions = 0.5 mol CaCl2 * (3 moles ion / 1 mol CaCl2)

<span>Total number of ions = 1.5 moles ion</span>

The lightest atom is the hydrogen atom. There is one proton in its nucleus.
Aneli [31]

Hydrogen is the smallest chemical element because it consists of only one proton in its nucleus. Its symbol is H, and its atomic number is 1 .It has an average atomic weight of 1.0079 amu, making it the lightest element.

a.1.00784 u

b.Atomic-36

Kr

Krypton

Atomic Weight. 83.80

That means that there must be a balance between the positively charged protons and the negatively charged electrons. Atoms must have equal numbers of protons and electrons. In our example, an atom of krypton must contain 36 electrons since it contains 36 protons. Electrons are arranged around atoms in a special way.
