What are some physical properties of metals
Hardness, state malleability ductillity
What are some physical properties of non-metals
How do you find Density
D = m/V
How do you find Volume
How do you find Mass
What is the maximum number of electrons that the first orbit can hold
The first orbit can hold 2 electrons
What is the difference between a Bohr diagram and a Bohr-Rutherford diagram.
A Bohr diagram only shows electrons while a Bohr-Rutherford diagram shows electrons, neutrons, and protons
Whart types of things are indicators of a chemical change
New Colour
Bubbles
Heat or Light
New Substance
New Odour
What is the differene between an atom and an ion
An atom has the same amount of protons and electrons. An ion is an electrically charged particle produced either by adding or removing electrons from a neutral atom
What are the 3 parts of an atom
Electrons
Protons
Neutrons
Where is the Electrons located
They orbit the nucleus
What type of charge do electrons have
They have a negitive charge
Where are protons located
They are located in the nucleus
What type of charge do protons have
They have a positive charge
Where are neutrons located
They are located in the nucleus
What type of charge do neutrons have
They have no charge, but they do amount to the mass
What does a flaming splint test for

What happens when you do a flaming splint test
You will hear a high pitch “pop”
What does a glowing splint test for
It will test for oxygen gas
What happens when you do a glowing splint test
You will see the splint relight
What happens when you do a lime water test
It will test for carbon dioxide gas
What happens when you do a lime water test
The liquid will go cloudy after pouring the lime water gas.
When is hydrogen treated as a non - metal
If it comes second in the formula
