It all depends on if you know the mass number and atomic number then you will be able to find out what the amount of neutron in an element.

What is pH and its importance?
- pH is an important quantity that reflects the chemical conditions of a solution.
- The pH can control the availability of nutrients, biological functions, microbial activity, and the behavior of chemicals.
- The pH is then calculated using the expression: pH = - log [H3O+].
- The solubility of an ionic compound is affected by the hydronium ion concentration.
- Addition of H₃O⁺ to the anion of a weak acid, increases the solubility of the ionic compound.
Therefore, the pH of the solution is also increased.

I believe it's alkali metals and alkaline earth metals.
The density of water at 12°C is lower than the density of water at 20°C.
Now density is related to volume as per: density = mass / volume =>
mass = volume * density.
So, the greaer the density the higher the mass of the same volume of water.
Therefore, 100.0 ml of water at 12°C has a mass greater than 100.00 ml of water at 20 °C.
So 6.02*10^22 is avogadro constant, which is the amount of atoms in one mole. If you look Xenon up in the periodic table you will find it's mass given <span>131,293, which is grams per 1 mole.
