The number of neutrons is equal to the atomic weight minus the number of protons
EX: The number of neutrons in Gold =
Proton, Electron, and Neutron

The number of electrons is the same as the number of protons.
EX: The number of electrons in Gold =
Atomic Weight (round to the nearest whole number)

FOR EVERY POSITIVE CHARGE YOU HAVE, YOU MUST HAVE A NEGATIVE CHARGE. THAT IS WHY THEY ARE EQUAL :)
Let's Practice :)
Each element has it's own place on the table. Within each box on the table, there is information about the elements atomic number, atomic symbol, and atomic weight.
All of this information can help YOU determine how many protons, electrons, and neutrons are found in an element.
The number of protons is the same as the atomic number
EX: The number of protons in Gold =
A proton can be defined as having a positive charge. An electron can be defined as having a negative charge
A Neutron can be defined as having a neutral charge

Scientists used information about elements to create the periodic table of elements
