- Atomic Structure
- Protons, Neutrons and Electrons
- An atom has the same number of protons as electrons.
- Protons have have a positive charge.
- Electrons have a negative charge
- A proton nearly has the same mass as a neutron.
- The nucleus is made up of protons and neutrons
- Isotopes
- Isotopes of the same element have different masses, the same number of protons and electrons; different numbers of neutrons in the nucleus.
- Different isotopes of the same element react in the same way because chemical reactions involve electrons and neutrons make no different to electrical activity.
- Atomic Structure of Ions
- Many atoms react by gaining or losing an electron to form ions
- Ions are charged because they have different number of electrons and protons
- Key Words: Proton, Neutron, Electron, Isotope, Atomic Number, Mass number Ions
- Isotopes are atoms of the same element with different numbers of neutrons.
- Atomic number is the number of protons in the nucleus of an atom.
- Mass number is the number of particles in the nucleus.
- An ion is a positively or negatively charged atom or group of atoms.
- Protons, Neutrons and Electrons
