what are the three subatomic particles Correct Answ_neutrons, protons, electrons
nucleus Correct Answ_core of an atom
,proton Correct Answ_positively charged (in nucleus)
neutron Correct Answ_neutral no charge (in nucleus)
electrons Correct Answ_negatively charged in a cloud around the nucleus
number of protons =? Correct Answ_number of electrons
atomic number is what Correct Answ_number of protons/electrons
mass number Correct Answ_sum of protons and neutrons
isotopes Correct Answ_Atoms of the same element that have different numbers of neutrons
radioactive isotopes (radioisotopes) Correct Answ_An isotope of an atom that spontaneously
emits one or more types of radioactivity into stable configuration
,half-life Correct Answ_the time it takes radioactive isotope to decay into half
atomic mass/weight Correct Answ_average of the natural occurring isotopes

unstable-become stable by gaining or losing from another element (this breaks apart important
elements) UV rays, x-rays
ionic bond Correct Answ_force of attraction between oppositely charged ions
, cation Correct Answ_positively charged ion-loses an electron
anion Correct Answ_negatively charged ion-gains an electron
electrolyte Correct Answ_an ionic compound that breaks apart into positive or negative ions
in a solution
covalent bond Correct Answ_two more more atoms share electrons
non-polar Correct Answ_equal sharing of electrons
polar Correct Answ_sharing of electrons is unequal
electronegativity Correct Answ_power to attract electrons to itself
