If a nucleus has #44# positively charged, massive particles, and #62# neutral, massive particles, what is the nucleus, and how do we represent it?
Ruthenium metal has
How did I know this? Well I have access to Periodic Table, so I simply looked it up. If you are doing your chemistry or fysics homework there should be a Periodic Table near at hand to you. No one expects you to memorize the Table, tho you do have to learn how to use it. A simple copy of the Periodic Table should also be made available to you in every examination of chemistry and physics you ever sit. You cannot be expected to memorize
We have accounted for 44 of the massive particles in the ruthenium nucleus. The remainder
Certain isotopes, such as this one, are unstable, and they can be used, as here, in nuclear medicine.
