When a material has an excess of electrons, it has a negative charge. When it has a deficiency of electrons, it has a positive charge.
No, only protons and neutrons exist in the nucleus of an atom. Electrons are what produce a negative charge.
When a material has an excess of electrons, it has a negative charge. When it has a deficiency of electrons, it has a positive charge.
"Neutral charge" doesn't exist; the meaning of neutral is zero electrical charge.
restricted to discrete multiples of a fundamental unit of charge (elementary charge). This means that charge can only exist in specific, whole number multiples of this unit, and cannot exist as a continuous range of values.
The telephone company does not exist.
There are only two kind of charge particles, the positive and negative charge particle. The positive charge is called proton and the negative charge is called electron. There are also numerous other charge negative, positive particles out there beside the one mention here but they only exist in a fleeting amount of times then disintegrated into pure energy.
No, not all matter has a negative or positive charge. Matter can be neutral, meaning it has an equal number of positive and negative charges, such as in most atoms. Charged particles exist in matter, such as electrons with a negative charge and protons with a positive charge.
Oxygen atoms do not possess a net positive charge. They typically exist in a neutral state, with equal numbers of protons (positive charge) and electrons (negative charge).
The charge is +2 but this ion doesn't exist.

In a conducting sheet, the electric field is zero inside the material but can exist on the surface due to excess charge redistribution. In a non-conducting sheet, the electric field can exist both inside the material and on the surface, depending on the charge distribution.
The charge of a Pb ion can vary depending on the specific ion. Commonly, lead can exist as Pb2+ or Pb4+ ions.
