An alpha particle is: a hydrogen atom nucleus of helium two neutrons an electron
Weegy: c)neutrons and protons User: A false statement concerning matter is: Matter cannot be subdivided. Matter is composed of many small particles called atoms. Matter is mostly empty space. All matter contains mass. Weegy: 1.Matter cannot be subdivided. User: Which statement is true? Isotopes are atoms of different elements which have the same mass. Isotopes of a given element have equal numbers of neutrons. Isotopes of a given element have very similar chemical properties. Isotopes of a given element have equal numbers of protons and neutrons. Isotopes are atoms that have gained or lost electrons. Weegy: A: Isotopes are atoms of different elements which have the same mass. User: The atomic number of an atom is equivalent to the number of: neutrons protons electrons protons and neutrons alpha particles User: An alpha particle is: a hydrogen atom a nucleus of helium two neutrons an electron Weegy: An alpha particle is a NUCLEUS OF HELIUM.
