Positive & Negative charge of Tungsten

Click For Summary
SUMMARY

The discussion focuses on calculating the total positive and negative charge in a 50g Tungsten ring. The standard atomic weight of Tungsten is 183.84. Each Tungsten atom contains 74 protons and 74 electrons, contributing a negative charge of -1.6 x 10^-19 C per electron. The participants clarify that the total charge should account for all electrons and protons in the ring, not just those in the outer orbital.

PREREQUISITES
  • Understanding of atomic structure, specifically protons and electrons
  • Familiarity with charge calculations in Coulombs
  • Knowledge of the standard atomic weight concept
  • Basic arithmetic for multiplication and summation
NEXT STEPS
  • Calculate the total number of Tungsten atoms in a 50g sample using the molar mass
  • Learn about the concept of charge neutrality in atoms
  • Explore the implications of electron configuration on chemical properties
  • Investigate the role of protons and electrons in determining atomic charge
USEFUL FOR

Students studying chemistry, particularly those focusing on atomic structure and charge calculations, as well as educators looking for practical examples of atomic charge in elements like Tungsten.

ok, so how many atoms are there in the ring?

and how much charge in each atom? :smile:​
 
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)
