The charge of an electron cloud is negative. The electron cloud is made up of electrons, and the electrons are negatively charged. The electron cloud will have a negative charge as well.
The region of an atom in which the electrons move is called the electron shell, or electron cloud.
The nuclear charge in the 4th shell of an argon atom is +18, as argon has 18 protons in its nucleus. The nuclear charge is equal to the number of protons in the nucleus of an atom.
In a neutral atom, the charge on the electron cloud is balanced by the carge on the atom's nucleus. The nucleus has a positive charge proportional to the number of protons in it. This attracts and holds the negatively charged electrons in the electron cloud. And in a neutral atom (not an ion), there will be as many electrons in the electron cloud as protons in the nucleus. The charges will balance.
The electron cloud or electron shell
The part of the atom that has a negative charge is the electron. Electrons are located in the electron cloud surrounding the nucleus of an atom and contribute to the atom's overall negative charge.

The outer shell of an atom is populated by electrons, which have a negative charge. Protons, which have a positive charge hang out in the nucleus of the atom.
Atoms can have a positive, negative, or neutral charge. Protons have a positive charge, electrons have a negative charge, and neutrons have no charge (neutral). The overall charge of an atom is determined by the balance of protons and electrons.
you can tell an atom has a negative charge if its outer shell is not stable(happy)/full
The electron cloud or electron shell
Electrons
The charge of the electron cloud in a chlorine-37 atom is -17 (the number of protons in the nucleus). This is because an atom is electrically neutral, so the number of protons (positive charge) in the nucleus must be balanced by an equal number of electrons (negative charge) in the electron cloud.
The part of the atom that has a negative charge is the electron. Electrons are located in the electron cloud surrounding the nucleus of an atom and contribute to the atom's overall negative charge.
The electrons on the outer shell
Protons in the nucleus each have a positive charge, and electrons, surrounding the nucleus in the electron cloud, have a negative charge.
