The subscript (19) indicates that this atom has 19 protons (as well as 19 electrons). The supersript (40) denotes that it has 40 protons and neutrons, hence we can infer that it has 21 neutrons.
The meaning of this subscript is the base of a specific logarithm; example: log10, the usual logarithm with the base 10.
Superscripts tend to be reserved for exponents, charge symbols and very little else. Subscripts commonly show what type of data is on display. For example if you have variable "t" in your equation (=time) then subscript "0" would mean when t=0...in other words, at the start of the experiment. Rate constant (K) is also prone to having subscripts attached, again they tell you about what this K relates to. Seeing "obs" as subscript tells you this is an observed rate constant, one that has been gained via experimental procedure rather than theoretical calculation.
The subscript is the number of atoms.Example: U3O8Uranium octoxide has 3 uranium atoms and 8 oxygen atoms.
There is one atom of that element in the molecule.

Kw is called the water autoprotolysis constant or water autoionization constant
jet the f**k out
It means f*€k you I don't want to talk..
This is usually an acronym for "crack the f**k up" or "cheer the f**k up".
It means: O- oh M- my G- god W- what T- the F- f**k oh my god what the f**k
Don't give a f**k
Let's F**K later
it means f**k you
Down To F**k The World (:
getting weak as f**k
go f@#k yourself. the phrase means go f@#k yourself lmao
