It is a number that is approximately equal to 1.4142. Since it is an irrational number, any decimal representation must be an approximation. However, if you have a pair of compasses, it is not that difficult to mark sqrt(2) on the number line.

It'll be between 1 and 2
about 1/3 of the distance from 1 to 2
Negative square root is -√Square root of negative one is i.
You can represent a radical with a rational exponent. For example the nth root of a number m can be written as m1/n . If n was 2 for example, then it is the square root. So square root of 3 or radical 3 is written sqrt(3) or 31/2 .
At the number 2, draw a vertical line (perpendicular to the number line) and mark a distance of 1 unit on this line. Call this point X The distance from 0 to X is sqrt(5). Put a compass with its point at 0 and the pencil at X, and then draw an arc to cut the number line. That will be sqrt(5) on the number line.
