A negative charge:
Protons = positive charge.
Neutron = neutral charge.
Electron = negative charge.
Electrons have negative charge. They are present outside the nucleus.
The charge of an atom's nucleus is determined by the number of protons it contains since protons have a positive charge. In this case, with 11 protons, the nucleus has a total charge of +11. Electrons, which are negatively charged, balance this charge, but they are not part of the nucleus. Therefore, the charge of the nucleus remains +11, regardless of the number of electrons present.
A positive charge
To determine the number of protons and electrons for an atom or ion, you need the atomic number and the charge. The atomic number indicates the number of protons, while the charge tells you how many electrons are present. For a neutral atom, the number of protons equals the number of electrons. However, if the ion has a positive charge, it has fewer electrons than protons, and if it has a negative charge, it has more electrons than protons.
Protons, neutrons, and electrons are the atomic subunits present in equal numbers in an atom. Specifically, the number of protons (positive charge) is equal to the number of electrons (negative charge), while the number of neutrons (neutral charge) can vary to create different isotopes of an element.
Electrons have negative charge. They are present outside the nucleus.
Protons have a positive charge, Electrons have a negative charge, and Neutrons have a neutral charge. Neutrons help to ground the charges of protons and electrons.
In a conductor, free electrons are present that can move when an electrical charge is applied. These free electrons are responsible for the flow of current through the conductor.
Electrons charge is a negative
The charge of an atom's nucleus is determined by the number of protons it contains since protons have a positive charge. In this case, with 11 protons, the nucleus has a total charge of +11. Electrons, which are negatively charged, balance this charge, but they are not part of the nucleus. Therefore, the charge of the nucleus remains +11, regardless of the number of electrons present.
No, this is because an Ion is only present when there is a loss or gain of electrons, meaning that it's only present from it being positive or negative, therefore it cannot have a neutral charge.
q = Ne N = q/e Where: q = charge that can move N = number of electrons gained or lost e = elementary charge (1.602x10^-19)
A positive charge
The C4- ion has a total of 18 electrons. Carbon normally has 6 electrons, but the negative charge of -4 means that there are 4 extra electrons added to the ion.

(Atomic number) - (Number of electrons present) = (overall electrical charge of atom)
