a. True
b. False
Answer:
false
Explanation:
B.the atom with the smallest radius and the most valence electrons
C.the atom with the largest radius and the fewest valence electrons
D.the atom with the largest radius and the most valence electrons
Answer: Option (d) is the correct answer.
Explanation:
A metal which has the largest size and the most valence electrons would have the highest conductivity because the larger is the size of a metal the more freely electrons can move in it. Hence, the metal can conduct electricity.
If the atom is smaller in size then the electrons will be tightly held around the nucleus and hence they won't be able to move freely. Therefore, they will not conduct electricity.
Thus, we can conclude that the atom with the largest radius and the most valence electrons would have the highest conductivity.
Answer:
D. the atom with the largest radius and the most valence electrons
Explanation:
(1) decreases
(2) increases
(3) remains the same
Answer: Option (1) is the correct answer.
Explanation:
Kinetic energy is the energy that arises due to the motion of molecules. Average kinetic energy involves the sum of vibrational, translational and rotational kinetic energies.
When we decrease the temperature then the movement of molecules starts to decrease. As a result, there will be decrease in the average kinetic energy of its particles.
Thus, we can conclude that as the temperature of a substance decreases, the average kinetic energy of its particles decreases.
Coal and natural gas came from swamp environments, while oil came from open oceans.
B.
Coal came from swampy environments, while oil and natural gas came from open ocean environments.
C.
Coal, oil, and natural gas came from swamp environments.
D.
Natural gas and oil came from swamp environments, while coal came from open oceans.
Which is true about fossil fuels? The statement that is true about fossil fuels is Coal came from swampy environments, while oil and natural gas came from open ocean environments. The answer is letter B. The rest of the choices is not true for fossil fuel
