Neither really - it is called a 'tick' or a 'checkmark'
It is the mark used by people that are checking lists or work to indicate that what is written is correct or has been checked. You can use it to tick
things off a list once they have been done.
Teachers use it to indicate a correct answer and they use a cross 'x' to indicate something is wrong. It has no mathematical or chemical meaning
afaik.

It also looks like a short-hand version of "square root."

I second the motion!
A checkmark looks more like a "v" with one leg longer than the other.

I see where you are coming from with the square root symbol - but the question wasn't 'what is this symbol' it was ' what is the checkmark used for
in chem and maths' (well that's how I understood it). The checkmark, I assume is what guys in the USA call a tick (the Nike symbol) and as far as I am
aware that symbol has no meaning in maths or chemistry... but I will be happy to be taught otherwise.

Lets get clarification from the OP... Soma, do you mean a tick(checkmark) or a square root symbol?

A check mark, checkmark or tick is a mark (✓, ✔, etc.) used (primarily in the English speaking world) to indicate the concept “yes” (e.g.
“yes; this has been verified”, “yes; that is the correct answer”, “yes; this has been completed”, or “yes; this [item or option] applies
to me”).
(Wikepedia-Check Mark)
The check mark has no ties to chemistry or mathematics, It's simply a symbol for "Correct" or "Yes"
The symbol is derived from the roman word "Veritas," meaning true.
"The check mark is believed to have been created during the Roman Empire. "V" was used to shorten the word "veritas", meaning 'true'. This was used to
indicate yes, true, or confirmed on items in a list. Over time, its design started to change. When people started attempting to speed-write, the right
side became elongated."

Probably to avoid confusion with the numeral 5 - V
I can believe that of the Romans - They were very organised. I can imagine them being fans of check lists.
We do need to know if the OP means a tick (as we say in English) or a square root though. I think he means a tick.

The thing for me is the little "leg" on the leading edge (from the left). A check or "tick" mark (as some say) doesn't typically (so far as I know)
have this. The "square root" short hand frequently does.

The little leg you speak of is often times there as the pen is moving toward the paper in anticipation of scribing the check mrk. Like writing sloppy
or too fast and letters get a little extra pizazz. Personally I alwayse make sure to tabletop the back half flat on the root symbol, even when
writing fast. It looks to me as a normal check mark or super sloppy root. Also looks like the pic was drawn with a mouse or touchpad which may not
faithfully represent every nuiance of the intended pattern.

I concur.. a square root would have the tabletop. I assumed checkmark/tick as that is what was stated in the title of the thread.

See photo attached of the square root symbol in Excel (character code 221A).

Looks like Microsoft have opted to remove the tabletop from the root symbol in Excel - Bloody Americans! 
Microsoft really piss me off sometimes. If I have a mk2 car and upgrade to mk 3 then I expect the steering wheel, clutch, break, handbreak etc to be
in the same place it was for the mk2.... unless there is a really good reason for the change. Every upgrade they bring out you have to relearn the
package to essentially do exactly the same jobs you used to do with the previous upgrade... I would also expect them not to change internationally
standard symbols. People see this shit as the norm in this day and age where as they should be outraged. hmm.. rant over for now. lol.

Why use shorthand at all? It is an internationally standard symbol. Who came up with the idea that a)it needed shortening b) it was OK to change the
symbol c) to change it to an already well recognised symbol in use as a tick. d)Microsoft are allowed to change whatever symbol they like and the rest
of the world have to accept it. ??
This is why there is so much miscommunication around the world. When are the USA going to get into the 20th century* with regard to using
internationally standard symbols and SI units? It is embarrassing.

Just some perspective for you, here is a list of the worlds countries along with the year they converted to metric. As you can see, the USA isn't on
that list at all. The system has been around pretty much as long as your country has. With the addition of Myanmar and Liberia to the list this just
leaves ONE country not on the list playing ball with the rest of the ENTIRE world. Is it some backwater country where all of the population are too
stupid to care what the rest of the world thinks? No! It is America. wtf!? Congrats - you came LAST in this race and it isn't really acceptable when
it is something as important as this. Pull your heads out.
