Whenever there's only one X or one E, do we have to write a subscript of "1," or do we just write "X" and "E?" I have both in my notes and want to make sure I do whatever is preferred. Thank you!

If there is only one, simply writing just the letter X or E is enough. The subscript of 1 is redundant.

I don't think it matters, as if you don't, common sense tells you that the subscript is 1, and if you do, you definitely wouldn't get marked down for it.

I think writing only X or E is fine when there is only one.

If there is only one X or E there is no need to write the subscribe 1 on it. However, if the number is greater than 1; you should write down the number.

And along the same thread, if there is no E, you don't have to write E with a subscript of 0, you can just write AX4 or whatever

I think its good to write just the E if it has one lone pair. If there is no lone pair, then the E shouldn't be placed on the formula.

When there is only one X or one E, writing just X or E would be fine.

Writing the subscript of "1" would be unnecessary. Just writing X or E is fine.

I don’t believe you have to write the subscript of one. If you think about the chemical formula of a molecule, like H2O, you only write the subscript on the element that has multiple atoms present (Hydrogen), while you do not write the 1 for the subscript on the oxygen. You can apply this thinking to the VSEPR formulas. Thus, I believe writing the subscript is unnecessary and simply repeats what we already know, but if it is helpful for you, I don’t think it’ll do any harm.

Writing just E is fine.

there's no need to write the "1" subscript for X and E!

No it doesn't matter, in the book it usually doesn't put the one. I think that is just implied that there should be a one. Obviously for the other one when it is E2 you should definitely put the number.

You do not have to write a subscript if it is just 1, it's like math.

When there is only an X or an E, it is implied that there is one of those.

You don’t need to write the subscript 1.

You don’t have to write the 1 but if you prefer to then you can

Just like when writing chemical formulas the subscript of 1 isnt neccessary

The 1 isn't compulsory but I believe it depends on your preference.

You don't have to write a subscript if it is just 1 but you can if you want.

You can just write X and E without a subscript

The subscript isn't needed as it is just assumed there is only one.

Simply write the letter X or E for a subscript of 1. In addition, if it's a subscript of 0, don't write the letter.

I do not think that you have to, basically like in math.

You can just write one X or E- it's like writing X in an equation.

The 1 is unnecessary.

the one is not needed

I don't think it matters. I've seen people do both, in my plf sessions they do use the subscript though.

Whenever there's only one X or one E, we do not have to write a subscript of "1" - we just write "X" and "E," respectively.

I think writing simply X or E would be sufficient.

just writing the X and the E is good enough

I think it would be okay to just put AXE and the 1s would be redundant.

You don't have to write subscribts for X or E if it is 1. Only for 2 and above!

If there's only one X and E, the subscript of one is unnecessary.

Simply including the X and the E would suffice.
