Review of Atoms and the Periodic Table-2nd Period

Fill in the blanks by clicking on the blank, then choosing the correct term. Atoms with the same number of protons and electrons (positives and negatives) are considered to be neutralatoms. Protons are found in the nucleusof an atom, while electrons are found in energy levels. Neutronsand protonsmake up the nucleus of the atom. Where is most of an atom's atomic mass? In the nucleus In the energy levels Atoms do not have atomic mass It cannot be determined How can you determine an atom's atomic mass? Add the protons and electrons together Add the protons and neutrons together Add the electrons and neutrons together It cannot be determined Match the subatomic particles with their charge and mass. protons positive, 1 amu neutrons neutral, 1 amu electrons negative, 0 amu Fill in the missing spaces below.
