You need to be confident about this before you go on to the more difficult ideas about the atom which under pin a level chemistry.
Protons are positively charged electrons are negatively charged while the neutrons carry no charge. Thomson plum pudding model. They are so small that accurately predicting their behavior using classical physics as if they were tennis balls for example is not possible due to quantum effects. A simple view of atomic structure this page revises the simple ideas about atomic structure that you will have come across in an introductory chemistry course for example gcse.
