### Re: Lone Pairs and Lewis Bases

Lewis bases tend to have lone pairs and can "donate" to compounds that are Lewis acids or "accepters" of electrons.

### Re: determining electronegativity

I believe we've learned the trends of electronegativity of elements on the periodic table. (those closer to reaching octet by gaining electrons on the right vs those on the left)

### Re: Periodic Table Trends

Here are the things we've learned so far: Left to right of the periodic table: - ionization energy increases - electronegativity increases -electron affinity increases -atomic radius decreases Top to bottom: - atomic radius increases Bottom left: - more bottom left, the more metallic it is Top righ...

### Re: Sapling #14

Since H bonds happen between Hydrogen and F, O, or N, we use the context of the problem to concur O must be on either side of the H.

Best via formal charge is the one with formal charge closest to 0. And concerning bond length in regards to the sample question, average the lengths of those given in the question and the one closest to the overall length is your best choice.

### spectral lines

When solving for wavelength of emitted electromagnetic radiation, does the initial n level go as n1 or n2 in the equation "R*(1/n^2"1"-1/n^2"2")?
