Atoms form bonds with another to create molecules, sometimes this is hard to picture, hence we use models to make it easier to understand how/why they are formed

The buildup of molecules

https:

Build a water molecule with the program and upload a 3D picture of it with chemical bonds between the atoms

Build the other four molecules and take a picture of all 5 in your collection

H forms 1 bond, O forms 2 bonds, N forms 3 bonds, when you look at the periodic table, can you explain why they have the number of bonds they do?

Now go to collection 2 and build those five molecules, check each time if the number of bonds makes any sence

Take a picture of collection 2's molecules

Take a picture of collection 3's molecules

Now you are going to build the following molecules with the physical molecule kits.

C₂H₅OH        NH₃

C₄H₁₀              C₄H₈

_{HCN     NaCl}
