Density
The amount of matter, or stuff, in something
What is mass?
This is the smallest unit of an element
What is an atom?
Two or more substances combined together
What is a mixture?
This subatomic particle can be transferred or shared to form an atomic bond
What is an electron?
We used this to model different types of atoms
What is playdough?
How much space something takes up
What is volume?
A substance made of only one type of atom
What is an element?
A mixture with particles dissolved evenly throughout.
What is a solution? (What is a homogeneous mixture?)
This bond involves the transfer of electrons from the cation to the anion
What is an ionic bond?
What is density?
The formula that calculates density
What is mass divided by volume?
The subatomic particle with a positive charge found in the nucleus of an atom
What is a proton?
A mixture that has an uneven (non-uniform) arrangement of particles
What is a heterogeneous mixture?
This bond involves the sharing of electrons between two atoms
What is a covalent bond?
We calculated the density of this polar molecule using a scale and a graduated cylinder
What is water?
Something with a mass of 2 grams and a volume of 1 milliliter will have this density.
What is 2 grams per milliliter?
The subatomic particle with no charge found in the nucleus of an electron
What is a neutron?
This produces hydrogen ions when in solution.
What is an acid?
This bond involves the unequal sharing of electrons between two atoms
What is a polar bond?
We separated trail mix using this kind of change, which can be used to separate any mixture.
What is a physical change?
What is 0.2 grams per milliliter?
The number of electrons the second and third valence shells can hold
What is 8?
NaOH is an example of this.
What is a base?
This is what we call multiple atoms bonded together
What is a molecule?
In the acids and bases lab, this solution was the most acidic.
What is vinegar
