D) isotopes; neutrons
Explanation:
The diagram illustrates the three different isotopes of carbon. They vary by the number of neutrons.
Isotopy is the existence of two or more atoms of the same element having the same atomic number but different mass numbers due to the differences in the number of neutrons in their various nuclei.
- Isotopes of elements have the same electronic configuration
- They share the same chemical properties
- They differ in masses due the number of neutrons they contain.

Answer:
Potassium is more reactive
Explanation:
Answer:
While the water falls v increases and h decreases, so the kinetic energy increases and the gravitational potential energy decreases, and this happens in a way that the total energy is always the same. (If there is no friction)
Explanation:
I think it occurs whenever waves come together so that they are in phase with each other.
