Re: Reading the textbook [ENDORSED]

I definitely feel that the textbook has a lot of information that the finals and tests won't cover.

The textbook does have a lot of extra information that may not be covered, but it's a good comprehensive guide and the practice problems it introduces are good to do before midterms and finals.

Re: Showing Work for Limiting Reactant Calculations on Tests [ENDORSED]

Your final answer needs to have correct sig figs for full points I believe, and I think there is partial credit for longer problems.

Re: Rydberg equation [ENDORSED]

It is used for questions that involve wavelengths of light that are emitted when electrons change energy levels.

Re: Valence Electrons?

Valence electrons for the non metals can basically be counted just by going across the periodic table, for example; Li:1, Be:2, B:3, C:4, N:5, O:6, F:7, and Ne:8. And that pattern follows down the columns. For non metals, count across the periodic table. Each corresponding element should have the sa...

Re: Electronegativity

Electronegativity is the ability of an atom to attract electrons to itself when it is part of a compound. I think electronegativity decreases down a group and increases across a period. It is essentially how well an atom within a compound can attract electrons. Electronegativity decreases down group...

Re: Different forms of Energy

Re: Shower Thoughts: SUN

The sun does not employ typical combustion reactions. Instead of oxygen, it uses hydrogen molecules to convert them into helium. The fusion reaction produces heat and light.

Re: Rusty on High School Chem [ENDORSED]

I recommend buying a 3D molecule model kit (there's also a free program that Professor Lavelle provides for us) It makes things a lot easier when learning shapes and arrangements.

Re: Geometry vs molecular shape

Geometry means how both bond electrons and lone pairs are arranged, whereas shape only refers to the arrangement of the bond electrons.
