Script:

J: Macroscopic Observations are observations that can be seen, felt or smelled

M: Macroscopic Properties include, for example, the melting point, boiling point, heat of fusion, temperature, and these are all properties of large chunks of matter

H: Microscopic model is something that will be used throughout the course to explain the behavior of matter, so you guys should remember that.

M: So, an important difference between the mixtures of elements is that mixtures can have almost any composition that is desired.

J: So interesting!

M: Yes, indeed. Compounds will have definite composition

H: Which is an expiremental fact that leads us to the Law of Definite Composition

J: ooo

H: Every compound has a definite composition

M: But, it is also possible to make several compounds from the same elements! Which leads us to...

J: Law of Multiple Proportions!

H: Two or more compounds can have different proportions of the same element.

M: Particular compounds do not have multiple proportions like a mixture

J: So, so, what does atom mean anyways?

H: I really don't know honestly, why don't you just tell us straight up.

J: Okay man, it means the smallest possible piece of something. The spheres used to represent atoms aren't really what they look like

H: What are elements you guys, has that ever come to you guys?

M: Nope

J: No way

M: Why don't you tell us huh?

H: Yea, alright i'll tell you. Elements are also called pure substances which cannot be broken down. Thereforer, an element contains only one kind of atom. If more than one type of atom are present, then it should be possible to separate. Resulting in different substances with different properties.

M: Thank you for that Harriet

H: Yea no problem, just telling you

M: So does that mean that there are as many types of atoms as there are elements, because each element has its own type of atom?

J: I think so

H: I believe so, yea

J: Okay, an element can exist as a solid, liquid, or gas. Particles that have muiltiple types of atoms are called molecules.

H: Elements all have different melting points and boiling points, because it takes more energy to move more massive atoms than light ones.

J: Oh so interesting

M: Makes sense to me

J: It is generally true that the larger the particle, the higher the boiling point

H: Now let's talk about compounds. Since compounds are made of two or more kinds of atoms, the different atoms can be separated if enough energy is supplied to break the compound apart

M: Heat and electricity can supply the energy needed to decompose the compound

J: Compounds can exist as solid, liquid, or gas. I said it again. Not all compounds are made of molecules.

H: Ions are particles that have an electric charge

M: The only way to tell which compounds are ionic is to check them for conductivity

J: The end

H: Wooo no more accent

M: Thank you so much for watching y'all

H: Oh she still has an accent

J: Ehh the accent hurts my throat

H: Okay, I think we're done.
