Answer:
Be³⁺
Explanation:
Be³⁺ has only one electron since it has loss 3 electron and is therefore capable of having a line spectrum similar to hydrogen atom.
B) B. is the point where it has maximum potential energy.
Explanation:
- This an example of projectile motion.
- In projectile motion, the path of an object is illustrated in the picture given. In the given picture, the minimum kinetic energy and the maximum potential energy is at B
- B is the point where the object, for example, the ball is reaching its point of minimum kinetic energy which means that after this point the object's downward motion starts.
- Hence, the transition from the upward motion to the downward motion is the point where it has the maximum potential energy.
The particles will move faster and further apart. There will be more energy in the particles due to the heat.
Answer:
Explain your answer. mg2+ would be the smaller ion this is because each ion has the same number of electrons however mg2+ has a greater number of protons and therefore is more charge dense and the outer electrons feel a greater pull from the nucleus.
Hope this helps, have a great day/night, and stay safe!
