The nucleus is made up of protons and neutrons, this makes it posititvley charged by the atom overall has now overall charge. Therefore, the nucleus is positively charged and electrons are negatively charged, so the atom is neutral Relative masses, neutron: 1, electron: 0.

The reactivity of metals is determined by their position in the reactivity series Atoms: A nucleus of an atom is made up of protons and neutrons Relative charges, neutron: 0, electron: -1, proton: +1. Metal oxides are formed through reactions of metals with oxygen that involve gains or losses of oxygen. 'Giant (repeated) Ionic lattice', gives strong bonds as positive and negative ions are strongly attracted. txt) or read online for free. 2.
