can someone help me understand how to write a electron arrangement for elements such as Carbon, helium etc... how do you know how much electrons goes in each level?

Simple. Let's take Carbon. Carbon has an atomic number of six which means it has 6 electrons. Now orbital only gets a certain number of slots; order of orbitals goes as follows: s,p,d,f, etc... but we will focus only on these four. The s orbital has one slot, the p orbital has three slots, the d orbital has five slots, and the d orbital has nine slots. Each slots can house a total of two electrons: one spinning up and another spinning down (in order to maintain equilibrium). Now the more electrons an element has the more orbitals it will need. Back to carbon; having six electrons it will need 3 orbitals: 1s 2s and 2p To fill them in it would look like this: |dw:1362539038726:dw| Now when inserting electrons you always go from left to write with the positive spin going first, this is due to the earths magnetic field.
