atoms consist of? correct answersA NUCLEUS AND ELECTRONS - Nucleus has protons and electrons - Nucleus is positively charged due to protons - Electrons are negatively charged and orbit the nucleus atoms can bond together to make? correct answersMOLECULES atoms w/ an equal number of protons/ electrons are? correct answersNEUTRAL If the # of protons/ electrons are not equal correct answersIT IS AN ION W/ A + OR - CHARGE what is atomic radius? correct answersREFERS TO THE AVERAGE DISTANCE B/W THE NUCLEUS AND OUTERMOST ELECTRON - In reference to the periodic table, atomic radius increases as energy levels are added and decreases as more protons are added. - Atomic radius increases towards the left and bottom of the table. what is atomic number? correct answersREFERS TO THE NUMBER OF PROTONS IN THE NUCLEUS - Can be represented as "Z" - Atoms w/ a neutral charge have an atomic number equal to the number of electrons what is atomic mass? correct answersTHE MASS NUMBER - TOTAL # OF PROTONS/ NEUTRONS IN THE NUCLEUS OF AN ATOM - Atomic mass (A) A= Z + N (protons + neutrons) - Mass of electrons is insignificant what is relative atomic mass? correct answersATOMIC WEIGHT AND IS NOT SIMILAR TO ATOMIC MASS - Atomic weight is the ratio of average mass per atom of a sample to 1/12 of the mass of an atom of carbon-12 what are isotopes? correct answersA VARIATION OF AN ELEMENT THAT POSSESSES THE SAME ATOMIC NUMBER BUT DIFFERENT MASS NUMBER - A group of isotopes will always have the same # of protons/electrons, but vary in # of neutrons what is a stable isotope? correct answersISOTOPES THAT HAVE NOT BEEN OBSERVED TO DECAY OR NON-RADIOACTIVE ISOTOPES - Currently 80 elements have 1 or more stable isotopes
