Discussion Overview

The discussion revolves around calculating the number of electrons and protons in 1 gram of hydrogen, exploring the relationship between atomic weight, moles, and the states of hydrogen. The scope includes theoretical reasoning and mathematical calculations.

Discussion Character

  • Mathematical reasoning
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • One participant proposes using the concept of a mole and the atomic weight of hydrogen to deduce that 1 gram of hydrogen contains approximately 5.97 x 10^23 atoms, which corresponds to the number of protons.
  • Another participant notes that the number of electrons in hydrogen depends on its state, stating that hydrogen in gas and liquid forms has one electron per atom, while in plasma, it has no electrons.
  • A different participant confirms that 1 mole of hydrogen (6.022 x 10^23 atoms) would contain 6.022 x 10^23 electrons and protons, assuming the atoms are in a neutral state.
  • There is a clarification that while plasma state hydrogen has no bound electrons, the electrons are still present but dissociated from protons.

Areas of Agreement / Disagreement

Participants generally agree on the number of atoms, electrons, and protons in neutral hydrogen, but there is disagreement regarding the state of hydrogen in plasma and its implications for electron presence.

Contextual Notes

The discussion includes assumptions about the states of hydrogen and their impact on electron presence, which remain unresolved. There are also references to atomic weight and the calculations involved that may depend on specific definitions.

I was trying to figure out the number of electrons and protons in 1.00 gram of Hydrogen.

What answer did you get and how did you arrive there?

By the way: the two numbers should be the same.
 
The easy answer would be to use the concept of a mole as well as the known atom weight of hydrogen to deduce that 1 gram of hydron should have about 5.97 X 10^23 atoms. Hydrogen only has 1 proton thus the number of protons. How many electrons a hydrogen atom contains would depend on what state it is in. Hydrogen at its gas, liquid and I believe its should have one electron. Thus the number of atoms, electrons and protons would be the same.

Hydrogen in the plasma state would have no electrons.

the formula to figure out the number of atoms in 1 gm of hydron is

mass of sample, in this case 1 gram divided by the atomic weight of hydrogen which is 1.00794 times the avogadro number(N) which is 6.02213x10^23. So it would be (1 / 1.11794)X 6.02213x10^23 = 5.97x10^23.
 
Hydrogen in the plasma state would have no electrons.

The electrons are still there, but they are dissociated from the protons. The plasma itself is usually electrically neutral.
 
6.022 x 10^23 atoms of hydrogens weigh 1 gram (1.008g)...1 mole of hydrogen. 1 atom of hydrogen has 1 electron, and 1 proton. Therefore 1 gram of hydrogen would have 6.022 x 10^23 electrons and 6.022 x 10^23 protons.
