An atom has an 16 protons, 18 neutrons, and 13 electrons. what are its atomic number, atomic mass, and net charge?
o
atomic number = 16, atomic mass = 34, net charge = 3+
atomic number = 16, atomic mass = 34, net charge = 3-
atomic number = 34, atomic mass = 16, net charge = 3+
atomic number = 34, atomic mass = 16, net charge =
+

Atomic number = 16, Atomic mass = 34, Net charge= +3

Explanation:

i) Atomic number = Proton number = 16

ii) Atomic mass = Proton number + Neutron number

                         = 16 + 18 = 34

iii) Net charge= Proton number = Electron number (when element is in ground state or unreacted state)

But, proton number (16) is not the same as electron number (13), this means the element has lost 3 electrons

Thereore, the net charge is = 16-13

                                              = +3  

- aluminum and copper chloride.

- the chloride ion to separate the aluminum from the oxygen so that the aluminum can react with the copper ions (and the water molecules).
