Subscript on E

Postby Ariel Fern 2B » Sat Nov 16, 2019 8:52 pm

In the VSEPR formula, is it fine to put a subscript 1 on the E if there is one lone pair on the central atom? The answers in the book just have E, but I like putting E1 to let me know there is only one pair. For example, AX3E1. Thanks!

you could write the subscript if you prefer, but in most cases it'll be written as just E. this is because in chemistry it's usually implied that that abbreviation would have a subscript of 1.

ex: H2O, even though oxygen doesn't have subscript of 1, you know there's one oxygen atom

It shouldn't matter, just like how when writing the charge of a molecule in a lewis structure, you can write "-" on the top right of the brackets or "1-"

as long as you understand that if its just E, that means there's an invisible 1 there, it shouldn't really matter whether or not you actually put the 1 in when writing the answer

You can write it however you want :) they are the same thing, but putting a subscript of 1 may make it clearer for the person grading the exams.

You can put the subscript 1 on the E, but you don't have to. E1 and E are the same thing, so the 1 is pretty unnecessary, but if it helps you, it's okay.
