Re: Lewis acids and bases
Lewis acids are molecules that would accept electron and Lewis bases are electron donors so as an example molecules that have negative charges are likely Lewis bases
Re: Lewis acids and bases
Just to add, anions are rich in electrons so they donate their electrons (Anions are Lewis base)!

Lewis acids are elements that accept an e- while bases are those that donate e-

Re: Lewis acids and bases
If it has the capacity to accept electrons, then its a lewis acid, and if it has the capacity to donate electrons, then it is a lewis base. Some things that can help to look out for are charges, so if it has a positive charge, it can accept electrons, and is an acid, but if it has a negative charge, then it can donate electrons and is a base.
Re: Lewis acids and bases
A Lewis acid is any substance that can accept a pair of nonbonding electrons. It is an electron-pair acceptor
A Lewis base is any substance that can donate a pair of nonbonding electrons. It is an electron-pair donor. In other words, a lewis acid accepts and a lewis base donates.

Re: Lewis acids and bases
Do you have to draw the Lewis structure to tell if they’re an acid or a base?

I do not believe so

I don't think you need to but for me it's easier to draw one out to decide.

Re: Lewis acids and bases
I get the general rule, but how can we tell if a molecule can accept or donate electrons just by looking at the chemical formula?

In this case, it is easier to draw out the Lewis structure of the molecule to visualize how the electrons are distributed. Then it will be clear which atom is accepting the electrons and which atom is donating the electrons.

Re: Lewis acids and bases
Acids accept e- while bases are those that donate e-! Drawing out the lewis structure helps!

Re: Lewis acids and bases
Hi,
A Lewis acid accepts an electron pair, while a Lewis base donates an electron pair.
Hope this helps! :)

Re: Lewis acids and bases
Hey! I had the same question.
- Lewis acids accept an electron while Lewis Bases donate an electron.
- What helped me understand more was watching a youtube video about lewis acids and bases. Seeing different examples really helped. I suggest the organic chem tutor.

Re: Lewis acids and bases
If you need a way to remember them, I think of acids as electron acceptors (both start with the letter "a"). On the other hand, bases are electron donators (a lowercase "b" is a lowercase "d," but flipped!).

Re: Lewis acids and bases
Just something good to keep in mind is that coordinate covalent bonds are usually formed when dealing with acids and bases

Re: Lewis acids and bases
Hi! A Lewis acid is defined as a species that accepts an electrons. An example of a Lewis acid is BF3 and H+. A Lewis base is defined as a species that donates electrons. An example of a Lewis base is NH3 and F-. Hope this helps :)

Re: Lewis acids and bases
Lewis acids are usually positive cations, molecules without completely filled octets, and overall any compound that can accept electrons. Lewis bases are usually anions and electron-rich molecules. Hope this helps!

Re: Lewis acids and bases
A Lewis acid would accept electrons while a Lewis base would donate electrons.
