- Atomic structure and Bonding
- All atoms are made up of 3 subatomic particles: Protons, Neutrons and Electrons.
- Neutrons have no charge.
- Neutrons and Protons make up the nucleus.
- Protons are positively charged
- Neutrons and Protons make up the nucleus.
- The number of protons that an atom has determines what element you have.
- Electrons are negatively charged.
- Electrons are found around the outside of the nucleus in energy levels or shells.
- The energy level closest to the nucleus can hold a maximum of 2 electrons. All the others can hold a maximum of 8.
- e.g Sodium would be arranged: 2,8,1 because Sodium has 11 electrons.
- The number of shells tells you what period the element is in. The last shell tells you what group the element is in.
- If an element has a full outer shell then it has a certain amount of stability. Elements with full outer shells do not react e.g. Group 8
- The energy level closest to the nucleus can hold a maximum of 2 electrons. All the others can hold a maximum of 8.
- Electon arrangement in atoms.
- All atoms are neutral; the number of protons equals the number of electrons
- Electrons are found around the outside of the nucleus in energy levels or shells.
- Neutrons have no charge.
- Isotopes
- "Isotopes are atoms of the same element therefore they have the same number of protons but different number of neutrons."
- Bonding
- Atoms can gain full outer shells by bonding with other atoms.
- Ionic Bonding
- Covalent Bonding
- Atoms can gain full outer shells by bonding with other atoms.
- All atoms are made up of 3 subatomic particles: Protons, Neutrons and Electrons.
