The nuclear charge of an atom is the measure of the effect of attraction between the protons in the nucleus and the outer electron Electrons are attracted to the nucleus as they are negatively charged and the nucleus contains positively charged protons, but at the same time the layers of sub orbitals of electrons repel each other.Why is the nucleus positively charged in an atom?
Because the nucleus is only made up of protons and neutrons it is positively charged. Electrons revolve around the nucleus which is negatively its negative charge cancel out from the charge of nucleus and atom becomes stable. So nucleus positive charge plays an important role to give stability to an atom.What is the charge of an electron outside the nucleus?
Electrons are outside the nucleus in energy levels. Protons have a positive charge, neutrons have no charge, and electrons have a negative charge. A neutral atom contains equal numbers of protons and electrons. What is the charge on a sodium nucleus?What is the structure of the nucleus of an atom?
Atomic nucleus. An atom is composed of a positively-charged nucleus, with a cloud of negatively-charged electrons surrounding it, bound together by electrostatic force. Almost all of the mass of an atom is located in the nucleus, with a very small contribution from the electron cloud. Protons and neutrons are bound together to form a nucleus by...
