Proton

The nucleus contains positively charged protons and uncharged neutrons, so it is positively charged overall. Negatively charged electrons are found around it. Although diagrams often show a large, clearly drawn nucleus, they cannot usually show the real sizes to scale.

The nucleus contains two kinds of particle: positively charged protons and uncharged neutrons.

The nucleus contains protons, which are positively charged, and neutrons, which have no charge. This is why the nucleus is positively charged. Each electron has a negative charge.

The nucleus contains positively charged protons and uncharged neutrons, so it has an overall positive charge. Negatively charged electrons surround it at different energy levels, often called shells.
