SUMMARY

1 gram of hydrogen contains approximately 6.022 x 1023 protons and 6.022 x 1023 electrons, as derived from the atomic weight of hydrogen (1.00794) and Avogadro's number (6.02213 x 1023). The calculation involves dividing the mass of the sample (1 gram) by the atomic weight of hydrogen, then multiplying by Avogadro's number. In its gaseous and liquid states, hydrogen has one electron per atom, while in the plasma state, electrons are dissociated from protons, resulting in no electrons being associated with the hydrogen atoms.

PREREQUISITES
  • Understanding of Avogadro's number (6.022 x 1023)
  • Knowledge of atomic weight (1.00794 for hydrogen)
  • Familiarity with basic chemistry concepts, including states of matter
  • Ability to perform basic mathematical calculations involving division and multiplication
NEXT STEPS
  • Research the concept of moles in chemistry
  • Learn about the states of matter and their properties
  • Explore the implications of plasma state on atomic structure
  • Study the relationship between atomic weight and molecular mass
USEFUL FOR

This discussion is beneficial for chemistry students, educators, and anyone interested in understanding the fundamental properties of hydrogen and atomic structure.

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.
