Homework Statement
Which has the strongest ionic bond?
Cs2Se
AlN
CaI2
Kbr
Homework Equations
Look at electronegativities
The Attempt at a Solution
I looked at electronegativities and found the differences.
The largest difference was KBr. But apparently, that was wrong. See EN differences...

Solubility rules
The Attempt at a Solution
First, I balanced the reaction.
3Ca(OH)2 + 2H3PO4 --> Ca3(PO4)2 + 6H2O
The...
ohhh i understand. thank you
so i know you said that you didnt know about the n2s5.. but since it also doesn't dissociate, it it also 0 ions? does that make sense or no?
or would it be 2 ions for the n2 and s8? i don't really know, actually.
ohh right. yes, i was thinking of it wrong. but if i have something like 2s. then l= 0, and ml is also 0, right? so there's only 1 possible ml value there, so according to the original question, in a regular universe the max electrons is 2, so in this alternate universe, it would also be 2?
I don't follow this logic. For example, if it was 3p insetead of 2p, m ℓ would be -2, -1, 0, 1, 2 in normal universe. This would mean the max is 10, which is not true. The max is still 6.
Homework Statement
How many ions are present in 1 formula unit of HI(aq)?
HBr(g)?
N2S5?
Homework Equations
These two questions have the same concept, I believe.
I went the simple way and thought the answer was 2 for both of them, but apparently that was wrong. Can someone show me how to...
Homework Statement
In a universe different from ours, the laws of quantum mechanics are the same as ours with one small change. In this different universe the m ℓ quantum number obeys this rule.
mℓ = (-ℓ-1), (-ℓ),..,0,...(ℓ), (ℓ+1)
In this different universe, what is the maximum number...
