This technical assistance paper was developed to clarify specially designed instruction, core instruction and interventions within a multi-tiered system of supports (MTSS) for. educators developing, improving and maintaining systems of support for all students.
The charge of the electron is about -1.60217733 x 10-19 C, the charge of the proton is equal and opposite to that of the electron, both charges are constant.
The net charge of an atom is how the electrons and the protons balance out. If there an equal number of protons and electrons then it will have a net charge of 0. If there was more electrons than protons then it would have a negative charge overall. Flip that around and you get a positive charge.
