How much positive and negative charge are in a 50g Tungsten ring?

Positive & Negative charge of Tungsten
In summary, to determine the positive and negative charge in a 50g Tungsten ring, we need to first calculate the number of atoms in the ring. Then, we can determine the charge of each electron and multiply it by the total number of electrons in the ring to get the total negative charge. Similarly, we can calculate the charge of each proton and multiply it by the total number of protons in the ring to get the total positive charge.

welcome to pf!
hi soccerballboy! welcome to pf!
ok, so how many atoms are there in the ring?

There are 3 electrons in the outer orbital? and there is -1.6 x 10^-19 C Negative charge in each electron? So do I just multiply those two together?
Does that sound correct?

isn't it asking for the charge of all the electrons (ie not just the outer ones)?
(and, separately, all the protons)

I would like to clarify that the concept of positive and negative charge does not apply to an element such as Tungsten. Tungsten is a neutral element with an atomic number of 74, meaning it has 74 protons and 74 electrons, giving it a net charge of zero. The standard atomic weight of Tungsten is 183.84 grams per mole, which means that a 50g Tungsten ring would contain approximately 0.272 moles of Tungsten atoms. Each Tungsten atom would have a net charge of zero, but the nucleus would have a positive charge of 74 due to the 74 protons. Therefore, the total positive charge in a 50g Tungsten ring would be approximately 74 x 0.272 = 20.128 coulombs. However, this is not considered as "positive charge" in the traditional sense, as it refers to the charge of the nucleus rather than individual atoms. Overall, the concept of positive and negative charge does not apply to Tungsten in the context of a 50g ring.
FAQ: Positive & Negative charge of Tungsten
What is the positive charge of tungsten?
