what is particle theory
(extra points: why is it important?)
Particle theory is the idea that everything in existence is made up of particles. It is important in understanding the universe and how matter works.

What is a BohrRutherford diagram?
(extra points: Who were the two people most prominent in their development)
BohrRutherford diagrams are atomic models used to show the amount of elements in an atom. They were created by Niels Bohr working off the studies done by Ernest Rutherford.

What is a simple solution and how does it work?
(extra points: what example did sir use on the slideshow under solutes and soulvents?)
a simple solution is a mix of two substances, sir used matcha for an example.

what is density?
(extra points: what's the density of water?)
Density is the mass per unit of volume, depending on the state of matter. the density of water is 0.1 g/cm3
100
how many noble gases are there?
(extra points for each you name.)
there are 6 total noble gases, helium, neon, argon, krypton, xenon, and radon.
200
how many types of mixtures are there?
(extra points: what are they called?)
there are 2 types of mixtures, heterogeneous and homogeneous.

Which one of the following is a diagram for lithium?
(extra points: How do you know)
the 1st one, it has 3 protons, meaning its atomic number is three, which is the number for lithium
200
describe 3 physical properties of honey compared to milk.
milk must be kept cold so as to not curtail while honey can be left anywhere and won't go bad, honey is sticky and more viscous, honey is clear and milk is opaque, etc.
200
one of these three metals have a density lower than water, lithium, copper, or aluminum?
lithium

What is the point of the periodic table?
(extra points: name the forms of information it tells us)
The periodic table of elements was made to organize all known elements and make it easier to showcase their properties. When looking at the table of elements you will easily find the atomic mass, name, number and symbol.
300
fill in the blank, Particles are always _____?
(extra points: how does temperature affect this?)
Particles are always moving, cold causes them to slow while heat causes them to speed up.

run up to the board, show me a BohrRutherford diagram for aluminum, explain.

What does saturation mean?
(extra points: example)
saturation is when a substance is too much of a substance to be absorb

What element has the atomic symbol K?
(extra points: what is the atomic number)
Potassium, with the atomic number of 19.
400
what is it called when a solid becomes a gas?
(extra points: what is it called when a gas becomes a solid?)
when a solid becomes a gas it is called sublimation, and the opposite is called deposition.
400
how many electrons does Cl have?
(extra points: Run up to the board and draw a diagram.)
Cl has 17 electrons
400
when making instant coffee, what is the solvent and solute? Explain
(extra points: is it the same with coffee grounds, why?)
the coffee powder is the solutes, and the solvent the water, since the powder is being dissolved into the liquid, though with coffee grounds the grounds aren't able to fully dissolve because they saturate the liquid before being able to.

if the volume of an object is 550ml and the mass is 86g what is the density? (rounded)
the density of the object is 0.16ml/g3

when the periodic table was created, how many elements were there?
(extra points: who created the Periodic table)
when dimitri mendeleev created the periodic table there were 63 known elements.
