What are the four criteria used to define a “mineral”? artificial, organic, solid, distinct chemistry natural, organic, crystalline, indistinct chemistry natural, inorganic, crystalline, distinct chemical composition none of these Which of these is not found in the nucleus of an atom? positive charge neutron proton e lectron All atoms of the same element have the same atomic  number. True False All atoms of the same element have the same atomic  mass. True False

Positive ions are atoms that have gained electrons during  a chemical reaction. True F alse Atoms of the same element, sodium for example, have the  same number of in the nucleus.   Ionic bonding is where __________. atoms of different elements, having gained or lost electrons,  form negative and positive ions that are bonded together by  attractive forces between ions with opposite charges nuclei of bonding atoms exchange electrons; the resulting  ions are bonded together by the attractive forces between  the negative and positive nuclei atoms of two different elements share electrons and  protons; the resulting compound is bonded together by the  strong binding energy of shared protons nuclei of two different atoms share electrons, and the  resulting compound is tightly bonded by the very strong  electronuclear bonds

Which of these is correct for isotopes of an element? different number of neutrons, same number of protons same number of electrons, different number of protons different number of electrons, same number of neutrons different number of protons, same number of neutrons What physical property denotes the color of a powdered  mineral?    Match the following aspects of atoms and elements with
