Isotopes & Basic Atoms Structure

• Protons have mass of1, charge of 1 and are shown at Atomic Number.
• Electrons have negative charge (-) and very small mass (negligible).
• Protons actually make the element that specific element, if lithium didn't have 7 protons it wouldn't be lithium
• Isotopes are Atoms with the same atomic number but different mass number, means they have same protons but different neutron numbers.
• Ionisation meant that the atoms has lost or gained electrons and now has [atom] brackets around it
