In a "normal" atom, the number of electrons equal the number of protons. Many atoms, however, have missing or extra electrons, giving these atoms positive or negative charges, which we call ions.
In a normal atom, the number of protons is equal to the number of electrons. This balance is necessary for the atom to be electrically neutral.
The charge of an atom depends on the electrons compared to protons. Electrons being negatively charged, protons being positive. If there are more protons, the atom is positive, and if there are more electrons, the atom is negative.
The number of protons compared to electrons is what determines the charge of the atom. If there are more protons than electrons the atom is positively charged. If there's more electrons than protons the atom is negatively charged. Does this answer your question?
They are equal
The number of protons defines what element the atom is, and it also defines how many electrons the atom has in its various orbitals in a normal state.There is one electron per proton in an atom in a normal state.
In normal matter, the only charged elementary particles are protons and electrons. An electrically neutral object will have exactly as many protons as electrons. A charged object will have slightly more of one than the other. But under normal conditions, the difference is extremely small compared to the total numbers.
What do you mean by "normal" atom? There are ions: charged atoms or molecules. It is charged because the number of electrons do not equal the number of protons in the atom or molecule. An atom can acquire a positive charge or a negative charge depending on whether the number of electrons in an atom is greater or less then the number of protons in the atom. But I think a "normal" atom, would be a neutral one. A neutral atom has the same amount of protons as electrons, therefore have no net charge.
A version of an atom that has the normal number of protons but a different number of electrons is called an ion. If it has more electrons than protons, it is a negatively charged ion or anion. Conversely, if it has fewer electrons than protons, it is a positively charged ion or cation.
They are not always the same. It helps the atom be balanced.
Electrons are the particles of an atom that have little mass compared to protons and neutrons. Electrons are around 1836 times lighter than protons and neutrons.
The atom in a normal state would have two protons to match the two electrons, making the overall charge zero. If the atom is an ion, it would have an mismatched number of protons and electrons, giving it a positive or negative overall charge.
An atom with no electrical charge in its normal state has an equal number of protons and electrons. The number of protons in the nucleus of an atom is the atomic number, which is the same as the number of electrons in a neutral atom.
