Molecular naming conventions videos and transcripts

Molecular naming conventions was the topic of investigation for Molly (Grade 6 girl). Her topic was initially "Chemical reactions" until session 7 and then "Chemical bonds" until session 10.

Prior knowledge video

My topic is chemical reactions.

I don't really know much about chemical reactions but when you put two things together it makes something different, and that's practically all I know.

Completed explanatory animation

Atoms are the building blocks of matter. A molecule is a group of atoms. Atoms are sometimes named after the first letter:

H for Hydrogen.

C for Carbon.

They are sometimes based on the first two letters.

Li for Lithium.

Ti for Titanium.

Sometimes the letters have nothing to do with the element.

Au for Gold.

Ag for Silver.

A number following the element refers to the quantity of those atoms.

The number comes after the element.

For example, H2O means two hydrogens and one Oxygen, H2O4S  means two  hydrogens, four oxygens and one sulphur

The order in which the elements are written usually follows the rule developed by Edwin Hill in 1900.   According to this rule, when you have Carbon it goes first, Hydrogen is second and the rest are in alphabetical order.

Director's commentary

I changed from topic from “Chemical reactions” to “Chemical bonds” to “Molecular naming conventions.”

I liked how it went and how I made the letters light up when they were mentioned.

Brendan helped me with the animation and I like how he did some of the picturing.

So if you need to ever to learn about naming conventions just go to my animation.

Edwin Hill helped me get this animation correct and helped me get the actual information in order.
