Discussion Overview

The discussion revolves around the possibility of atoms having more electrons than protons, exploring concepts related to ions, electron configurations, and isotopes. Participants engage in clarifying these concepts and their implications in atomic structure.

Discussion Character

  • Exploratory
  • Technical explanation
  • Conceptual clarification

Main Points Raised

  • One participant questions whether atoms must have equal numbers of protons and electrons, suggesting a possible misunderstanding of atomic structure.
  • Another participant introduces the concepts of ions, cations, and anions as relevant to the discussion of electron and proton counts.
  • A participant seeks clarification on how to determine the populated electronic levels of atoms and references the Aufbau principle for electron configuration.
  • Examples of atoms with varying numbers of protons, electrons, and neutrons are presented to discuss their classification in the periodic table.
  • It is noted that the number of protons defines the element, while the difference between protons and electrons indicates the charge and whether the atom is an ion.
  • Participants discuss the concept of isotopes, confirming that atoms with the same number of protons but different neutrons are from the same element.

Areas of Agreement / Disagreement

Participants generally agree on the definitions of ions and isotopes, but there is some uncertainty regarding the implications of electron configurations and the classification of atoms in the periodic table.

Contextual Notes

Some assumptions about atomic structure and electron configuration are not fully explored, and the discussion does not resolve the complexities of how electron binding varies between different atoms.

Who May Find This Useful

Readers interested in atomic theory, chemistry, and the behavior of ions and isotopes may find this discussion relevant.

hi.
is it Possible that in atoms can be more electrons than Protons?

is not must to be Equal?

thanks
 
Chemistry news on Phys.org
Have you heard about ions? Cations? Anions?
 
oh yes thanks that truth.

THNAKS
 
but how can i know what is the Populated electronic level of Each atoms?

what is the Index fo this?
thanks
 
Not sure what you are asking about. Number of electrons in neutral atom is given by Z (nucleus charge), electron configuration can be found using Aufbau principle.
 
well let take Example:
we have atom A and atom B.
atom A have 15 Protons 18 Electrons and 16 Neutrons
atom B have 20 Protons 18 Electrons and 20 Neutrons.
so u can say that they are in the same Group?
or have the same Energy levels of Electron?

thanks.
 
Not only are they not in the same group, they are in different periods. It is the electron configuration of the neutral atom that determines its place in the periodic table, and consequentially the nucleus charge.

They do have the same electron configuration, however, but the electrons in atom B are much more tightly bound to the nucleus then the electrons in atom A.
 
Number of protons defines element, difference between number of protons and electrons defines charge and shows whether you have an ion (and what ion).
 
ok so if i have
atom C with 13 Protons 13 Electrons and 15 Neutrons
and atom D with 13 Protons 13 Electrons 14 Neutrons
i can say they are from the same element?

Yes, it is the same element, but different isotopes.

ok thank you so much
both of u.
