Answer:
The electrical charge of a proton in the nucleus of an atom is +1.
Protons are one of the three fundamental particles found in atoms, along with neutrons and electrons. They have a positive electrical charge, while electrons have a negative charge, and neutrons have no charge.
The symbol "+" represents a positive charge, so when we say that a proton has a charge of +1, it means that it carries one unit of positive charge. This positive charge of the proton balances out the negative charge of the electrons, which are found outside the nucleus, resulting in an overall neutral charge for the atom.
Step-by-step explanation:
To summarize, a proton in the nucleus of an atom has a positive electrical charge of +1.
