This property describes how shiny a material is
What is lusture
Wood burning is an example of this chemical property
What is flammability
An object with lower density than water will do what
What is float

Dimiti Mendeleev
A student notices one liquid pours much slower than another liquid. What is this propery?
What is viscosity
Iron reacts with water and oxygen to form this
What is rust
What is the formula to find density
Density equals mass divided volume
The coloumns on the periodic table are called these
What are groups/families
This family contains very unreactive metals
What is noble gases
Two solids have the same mass, but one takes up more space. Explain this property
What is density
Bubbles forming during a reaction shows this
What is a chemical change/reaction
Two objects have the same mass, although one is much heavier. Why does this occur
What is density
What does the row number of an element tell you about its Bohr/Bohr-Rutherford diagram
The amount of energy levels it has
What does the "staircase" seperate on the periodic table
What is metals and non-metals
This property describes how well heat moves through a substance
What is conductivity
The ability of a substance to react with another substance is called this
What is reactivity
A student claims "heavier objects always sink in water" is the true or false.
What is false since density matter, not just the mass of a object.
This substaomic particale has a negative charge
