- 1electronA minus-charged particle of an atom.
- 2neutronA neutral (no charge) particle found in the nucleus of an atom.
- 3protonA positive-charged particle in the nucleus of an atom.
- 4relative massA system of comparing atomic masses to carbon.
- 5ExplanationWeight is a measurement of the pull of gravity on an object or body. Mass is the amount of matter in a body or object. On Earth, mass has weight due to gravity. In space, however, an object can be weightless, yet have the same amount of mass.
- 6Three kinds of subatomic particlesThree kinds of particles make up an atom. The three kinds of particles are protons, neutrons, and electrons. All atoms except hydrogen have these three particles. Hydrogen does not have a neutron. It has only an electron and one proton.
- 7What do Protons havethey have an electrical plus (positive) charge (+); electrons have a minus (negative) charge (-). Neutrons do not have an electrical charge. They are neutral.
- 8In Review: Electrons and Atomic MassWhen you weigh yourself, whether or not you wash your hands before you step on the scales does not matter. The amount of dirt on your hands is so small that it would not affect your mass
- 9The atomic number of an atom is equal to the number ofprotons
- 10The atomic number is always equal to the atomic mass.false
- 11Atomic mass minus atomic number =number of neutrons
- 12A proton in the nucleus of an atom has an electrical charge of:+
- 13The atomic number of calcium is 20. This number means that calcium has 20 protons. The atomic mass of calcium is 40. How many neutrons does calcium have? (Remember: protons + neutrons = atomic mass.)20
- 14Helium has an atomic number of 2. This number also means that helium has 2 protons. The atomic mass of helium is 4. How many neutrons does helium have? (Remember: protons + neutrons = atomic mass.)2
- 15The relative atomic mass of a proton or neutron is1
- 16The relative atomic mass is always a mass that is compared to the elementcarbon
- 17Name the three kinds of sub-atomic particles found in an atom:Protons, Electrons and
Neutrons
