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.
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.
Yes. In the chemical formula H2O, the subscript 2 after the hydrogen means there are two hydrogen atoms in a molecule of water. The absence of a subscript after the oxygen means the subscript is understood to be 1, so there is one atom of oxygen in a water molecule.
I believe you mean scientific notation. 0.0000547 in scientific notation is 5.47 x 10-5.
In today's notation they represent 390

This is an ambiguous question. It might mean how do you type a character that is in the shape of a square, or how do you draw a square, or how do you make a superscript 2, indicating the mathematical operation of squaring a number. I am assuming you mean the last one. You can make any text a superscript (or a subscript) by selecting it and then clicking Font on the Format menu on the menu bar. In the Font tab (the default) in the Font dialog box, under the heading Effects, check the Superscript check box, then click the OK button.
