An atom is the smallest constituent unit of ordinary matter that has the properties
of a chemical ... The protons have a positive electric charge, the electrons have a
negative electric charge, and ...
Protons and neutrons are in the center of the atom, making up the nucleus.
Electrons surround the nucleus. Protons have a positive charge. Electrons have a
Atoms have positive protons, no charge neutrons and negative electrons. The

If an atom has an equal number of protons and electrons, its net charge is 0. ...
two (protons and electrons) carry a net electric charge, while neutrons are neutral
Relative masses and charges. Protons and neutrons have the same mass, which
is about 2,000 times larger than the mass of an electron. Protons and electrons ...
Protons and neutrons have nearly the same mass while electrons are much less
massive. If we assume that a neutron has a mass of 1, then the relative masses ...
How many protons, electrons and neutrons are in an atom of krypton, carbon,
oxygen, neon, silver, gold, ... By definition, atoms have no overall electrical
The constituents of the atom are protons, neutrons and electrons. The protons
and neutrons (nucleons) are found in the nucleus of atoms. The nucleus of an ...
The discovery of subatomic particles -- protons, neutrons and electrons -- did not .
... Neutrons are particles that have no charge and are about the same mass as ...
Proton (p<sup>+</sup>) is positively charged particle of the atomic nucleus. ... Atoms have an
equal number of protons and electrons; therefore, they have a no net charge.
