Fill in the blank: The number of protons in an atom of an element determines the atom's___, and the number of electrons determines ___of an element.

the number of protons in an atom of an element determines
the atom's (atomic number),and the number of electrons determines the (atomic number )of
an element.

the number of electrons in an atom=the no. of
protons=the ATOMIC NUMBER .

if you want to calculate the
neutrons number for an atom , you can easily make : MASS NUMBER- atomic
number

mass number = no. of positive protons and neutral
neutrons

 so,,,the atom consists of positive protons and
negative electrons (which resemble the atomic number) and the neutral neutrons
.
