Transcript of Proton, Electron and Neutron Notes

Proton, Electron, and Neutron
The three basic components of an atom are:
Proton, Electron, and Neutron

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
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.
Let's Practice :)
The number of protons is the
same
as the atomic
number
EX: The number of protons in Gold =
79
The number of electrons is the
same
as the number of protons.
EX: The number of electrons in Gold =
79
FOR EVERY POSITIVE CHARGE YOU HAVE, YOU MUST HAVE A NEGATIVE CHARGE. THAT IS WHY THEY ARE EQUAL :)
The number of neutrons is equal to the atomic
weight
minus the number of protons
EX: The number of neutrons in Gold =
Atomic Weight (round to the nearest whole number)

# of Neutrons
