Question

do the number of electrons and protons in an atom are same?

Answer 1

Yes.....the number positive charge are also equal to negative charge in magnitude......

Answer 2

By definition, atoms have no overall electrical charge. That means that there must be a balance between the positively charged protons and the negatively charged electrons. Atoms must have equal numbers of protons and electrons. In our example, an atom of krypton must contain 36 electrons since it contains 36 protons.
