Terms in this set (107)



Protons positive charge

, Neutron neutral charge


Electrons negative charge


Ion electrically charged atom(s) formed by the loss or
gain of one or more electrons


Isotopes forms of an element with different numbers of
neutrons


Atomic Number number of protons


Atomic Mass protons+neutrons


Identify the number of electrons in The number of electrons in the valance shell is
the valence shell of an atom based dependent on the atomic number. 2 in the first shell
on the atomic number, atomic mass, and 8 on each shell after.
and overall charge.


Covalent Bond strong attraction where 2 atoms share electrons


Nonpolar Covalent Bond equally shared electrons


Polar Covalent Bond not equally shared, spends most of its time closest
to the nucleus of the more electronegative atom.


Ionic Bond electrons in one atom are completely transferred
from one atom to the other


Positive Charge atom has more protons than electrons


Negative Charge atom has more electrons than protons
