Match these items: 1. alloy 2. gold 3. salt water 4. potassium 5. neutron 6. sugar 7. sodium 8. proton a. au b. no electric charge c. positive electric charge d. liquid solution e. solid solution f. compound g. na h. k they are not already in order

1. Alloy = Compound

2. Gold = Au

3: Salt Water = Liquid Solution

4. Potassium = K

5. Neutron = No Electric Charge

6. Sugar = Solid Solution

7. Sodium = Na

8. Proton = Positive Electric Charge

I'm sure these are the right answers, but if I got anything wrong, please feel free to state/comment about it. Hope this helps!!

Answer :

1. Alloy = Compound

2. Gold = Au

3: Salt Water = Liquid Solution

4. Potassium = K

5. Neutron = No Electric Charge

6. Sugar = Solid Solution

7. Sodium = Na

8. Proton = Positive Electric Charge

Explanation :

1. Alloy : It is a compound that is formed by the combination of one or metals with non-metallic elements. For example : Bronze is a type of alloy that is the combination of tin and copper.

2. Gold : It is chemical element with atomic number 79 and the symbol of gold is (Au). It is yellow, soft, malleable and ductile metal.

3: Salt Water : It is a liquid solution  that formed from the combination of salt and water .

4. Potassium : It is the chemical element with atomic number 19 and the symbol of potassium is, (K).

5. Neutron : It is a subatomic particle that is present inside the nucleus and it has no charge that means it is has no electric charge.

6. Sugar : It is a solid solution that formed from the combination of sugar and the water.

7. Sodium : It is a chemical element with atomic number 11 and the symbol of sodium is, (Na).

8. Proton : It is a subatomic particle that is present inside the nucleus and it has positive electric charge.
