Vin:
Okay the nucleus has 5 protons and 6 nucleons
so originally the atom had 5 electrons too .. and now as there are only 4 electrons the net charge is +1 as thw element has lost one electron and there is a surplus of 1 proton in the nucleus

I don't know the diagram so I am guessing that there are two atoms shown..one is neutral and one has +1 charged, so the mass remains the same as electrons have negligible mass.

(mentioning the year would help me a lot in giving an accurate answer ) ;)

elemis:
In the question below :


Is it CONCENTRATED aqueous Rubidium Chloride ?

OR

Is it DILUTE aqueous Rubidium CHloride ?

As you know the products will differ in each case, so how do I determine which one it is ???
