Neutral or no charge.
If an object has extra electrons, it will surely have negative charge.
positive
An atom that has the same amount of protons and electrons has no net charge and therefore is neutral.
Neutron are what keeps the nucleus together. Protons are what decides the kind of element which the atom is and the electrons decide the charge of the atom.
Since protons have a positive charge and electrons have a negative charge, an atom with more protons than electrons would have a positive charge. Note that an atom with this kind of imbalance is known as an ion.
Neutron= neutral Protons=positive Electrons=negative
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.
Electrons are extremely small compared to neutrons. Electrons have a negative charge and surround the nucleus in a kind of 'cloud'. Neutrons have no charge and are located in the nucleus of an atom.
Every proton in an atom's nucleus gives it a positive charge equal to the negative charge from the electrons orbiting the nucleus. The charge of the entire atom is neutral if there are an equal number of protons and electrons. If there are an unequal number of protons and electrons, the net charge of the atom, which is now an ion, is plus or minus e for each extra or missing electron. For example if an atom has 6 protons and 4 electrons, it has a charge of plus 2e.
When an atom gains or loses electrons and therefore becomes an ion, it takes on either a positive or negative charge (positive if it lost electrons, negative if it gained electrons) and can bond to ions of the opposite charge in an ionic bond.
Electrons are the smallest and lightest of the particles in an atom. Electrons are in constant motion as they circle around the nucleus of that atom. Electrons are said to have a negative charge, which means that they seem to be surrounded by a kind of invisible force field. This is called an electrostatic field.
Atoms lose electrons to form positively charged cations.
