    Electrons
In summary, the conversation is about different aspects of atoms and their properties. The main topics discussed are the number of electrons and protons in an atom, the concept of ions and their charges, and the electron configuration of atoms. It is mentioned that the number of protons defines the element, and the difference between the number of protons and electrons determines the charge. It is also noted that atoms with the same number of protons can have different numbers of neutrons, making them different isotopes of the same element.

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

is not must to be Equal?

thanks

Have you heard about ions? Cations? Anions?
 
  • #3
oh yes thanks that truth.

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.
 
  • #6
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).
 
  • #9
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?
 
  • #10
Yes, it is the same element, but different isotopes.
 
  • #11
ok thank you so much
both of u.
 

1. Can atoms have more electrons than protons?

Yes, atoms can have more electrons than protons. This is known as an anion, where the atom has gained one or more extra electrons and has a negative charge.

2. How does an atom have more electrons than protons?

An atom can have more electrons than protons through a process called ionization. This can occur through the gain of an extra electron from another atom, or through the removal of a proton.

3. What happens when an atom has more electrons than protons?

When an atom has more electrons than protons, it becomes negatively charged. This can affect the atom's chemical and physical properties, as well as its reactivity with other atoms.

4. Can an atom with more electrons than protons still be considered neutral?

No, an atom with more electrons than protons is considered to have a negative charge and is no longer neutral. However, if the number of electrons and protons are equal, the atom is considered to be neutral.

5. Is it possible for an atom to have an unlimited number of electrons?

No, an atom can only have a certain number of electrons. The maximum number of electrons that an atom can hold is determined by its atomic number, which is equal to the number of protons. For example, carbon has an atomic number of 6, so it can only hold a maximum of 6 electrons.
