Hi guys, just wanted to ask why an electron is written with an atomic number of -1 ?

Atomic number is for elements. However in nuclear equations, the same notation is used. It tells you the charge. This is because the electron's antiparticle, the positron is also written with the letter e. The difference is that the positron is positive, so it is writted with a plus sign instead.
This all makes a lot more sense when you start looking at nuclear equations. The top number and bottom number on both sides of the equation need to balance out. I suggest you google some nuclear equations for alpha and beta decay.
