In 1s^2 , the 1 m eans there is a -1 charge there is 1

In the notation , the number 1 refers to the principal quantum number, which indicates the energy level or shell of the electron. It does not represent a charge. The represents the type of orbital, and the superscript 2 indicates the number of electrons in that orbital. Therefore, in , there are 2 electrons in the 1s orbital.
