Periodic Table of the Elements
What is an Atom?
A substance that can't be broken down any further
What are the subatomic particles that have Positive, Neutral and Negative charges
Positive: Proton
Neutral: Neutron
Negative: Electron
What is the main reason that atoms Bond?
Because they want to satisfy the Octet rule
What is a Chemical Change
A bond where there is a change in the state of the matter and can not return to its original form
7

Atomic Number
Atomic Mass
Atomic Symbol
Atomic Name
What is an energy Shell
All of the rings that electrons flow on that surround the Nucleus
What is a Ionic and Covalent Bond
Ionic: A bond where electrons are transferred
Covalent: A bond where electrons are shared
What is a Physical Change
A change where there are no severe changes to the structure of the substance and can return back to its original state.
What is it called when the same atom has the same number of Protons and Electrons but a different number of Neutrons
An Isotope
What are the Rows In the periodic Table of the Elements called
Periods
What is the Valence Shell AND Valence Electron
Valence Shell: The outermost Shell that surrounds the Nucleus
Valence Electron: all of the Electrons that are on the Valence Shell
If a bond happens and there are more electrons than protons, what charge does the atom have
Negative
Chemical or Physical Change? Cutting an Apple
Physical change
What is an Ionic bond mostly made up of
Metal and Non-metal
What are the Columns in the periodic table of the elements called
Groups
What is the Octet rule?
The amount of electrons are allowed to be in each energy shell around the Nucleus
If a bond happened where there are more protons than ELectrons, what charge does the Atom have
Positive
Chemical or Physical Change? Baking a Cake
Chemical
Explain a Bohr diagram of the Atom
A diagram that shows the amount of Protons and Neutrons in the nucleus and then surrounding that information are every single electron on each of it's energy shells
