Answer:
- Cu (Copper)
- Al (Aluminium)
- Au (Gold)

2. How does metallic bonding work, what element types bond?

Answer:
The metallic bond is the force of attraction between electrons and metal Ions. the atoms have a strong bond because of the high melting point.

3. How do the valence electrons move around the bonded elements?

Answer:
Most metals have very few electrons in their outermost energy shells, and some have vacant outer electron orbitals. What this means for the metal is that its valence electrons are decentralized and free to move around.In covalent bonds, the electrons are shared between atoms.

4. Using the molecular kits make a model of one of the above material examples. 

6. What is the current of materials with metallic bonding, why is this?
Answer: The conductivity of materials with metallic bonding is very high. This is because of the way electrons move in a metallic bond. In a metallic bond, electrons are dislocated from the atoms, meaning they are free to float around between atoms (but still clump to positive atoms due to magnetic attraction). this means that any electro-motive force causes the electrons to move easily and that metallic bonds have a very low resistance to electron flow

7. From the above two questions, how could metallic bonded materials be used in your product? If you do not think it has any use justify your answer.
Answer: metallic bonded materials are very good conductors. This is why metallic bonded materials such as copper are used in electrical wiring.

8. From the last lesson you covered Lewis dot diagrams for single elements research how to draw up lewis dot diagrams for them, think how you would explain to someone the process you go through to draw this. (If not confident with this don’t worry it is going to be explained in class after this activity)

Answer: Draw on paper provided

2. How does Ionic bonding work, what element types bond?
Answer: ionic bonding is the complete transfer of valence electrons between atoms

3. How do the valence electrons move around the bonded elements?
Answer: When two elements become bonded, they each share one valence electron. 

4. Using the molecular kits make a model of one of the above material examples. 

6. What is the current of materials with Ionic bonding, why is this?
Answer:  

conduct electrical current. Ionic compounds are generally formed from metal and a non-metal elements.

6. What is the current of materials with covalent bonding, why is this?

Answer: The conductivity of covalently bonded materials is low as the electrons can not freely flow to create conductivity.

7. From the above two questions, how could covalent bonded materials be used in your product? If you do not think it has any use justify your answer.

Answer: A substance that covalently bonded is polymer. It is made up of a variety of molecules that are all strung together which makes long chains. It is widely used in a variety of products. The properties of polymer depend on the molecules that are bonded together. Polymer can be rubbery, sticky or a

Answer: 

Hydrogen (H2) two hydrogen atoms bonded together. 
Water (H2O) two hydrogen  & one oxygen.
Methane (CH4) one carbon & 4 hydrogen.

2. How does Covalent bonding work, what element types bond?

Answer: Covalent Bonding occurs when pairs of electrons are shared by atoms.

3. How do the valence electrons move around the bonded elements?

Answer: When two non-metallic atoms covalently bond, they share the electrons in their valence shells to gain stability. When the atoms bond, the electron shells merge to create a complete valence shell, then these electrons circle both atoms’ nuclei. For example, look at the molecule of water. Two hydrogen, with one electron in their valence shells, combine with one oxygen, with six electrons in its valence shell to create a grand total of eight electrons in the bonded valence shell. The molecule is now stable.
