Electron is the correct answer :D
Explanation:
covalent bond poor thermal conductivity
molecular compounds
metallic bond ductile
electron sea model
ionic bond crystalline
hard and brittle
Covalent compounds have the following properties:
- Gases and volatile liquids or low melting point solids
- Often insoluble in polar solvents
- Mainly non - conductors
- Have slow reactions
Metallic compounds:
- Have good malleability, ductility, electrical and thermal conductivity.
- A large sea of electron by jointly packed atoms.
- They are mostly in metals
- Accounts for the bulk of the physical properties displayed by metals
Ionic compounds:
- High melting and boiling point
- Soluble in polar liquids
- Conducts electricity in molten or aqueous forms.
- Mostly crystalline solids
- Usually hard and brittle
- Undergoes fast chemical reactions

Answer:
<span>Increasing concentration, temperature and surface area will increase the yield of products.
Explanation:
Concentration:
Increase in concentration of reactants will increase the number of reactants per unit volume. Therefore, the probability of collisions will increase hence, it will result in the increase in yield.
Temperature:
Increase in temperature increases the kinetic energy of reactants. Therefore, the increase in velocity of reactants results in the collisions with high energy. It makes it feasible for reactants to attain the optimum energy (activation energy) to convert into products with good yield.
Surface Area:
The reactants in grinded / powder form reacts fast as compared to solid form. In fact, grinding results in increase of the surface area of reactants. Greater surface area increases the probability of reactants to colloid. Hence, increases the yield.</span>
Answer:
Kinetic energy!
Explanation:
It measures the average kinetic energy of the molecules of a substance in degrees Fahrenheit (F) or Celsius (C).
Have a good day!!
