Explain why the electron configuration of 2-3-1 represents an atom in an excited state?

Chemistry
1 answer:
baherus [9]3 years ago
6 0

Answer:

See explanation

Explanation:

If we look at the electron configuration closely, we will discover that the element must have had a ground state electron configuration of 2,4.

This is because, the innermost shell usually holds two electrons while the outer shells hold eight electrons each. The four electrons must be accommodated in the second shell in the ground state configuration of the compound.

However, when the atom is excited, one electron from this shell may move to the third shell to give the excited state configuration 2-3-1 as shown in the question.

Answer:

Due to the decrease in the gravitational force, it will take longer time for ball to reach the ground while dribbling. Moreover, the hang time of players will also be longer. This means that the players will stay on air longer and will be able to jump higher.

We can change gas to a liquid by(Increasing, decreasing, removing) the temperature and (increasing, decreasing, removing ) the p
xz_007 [3.2K]

Decreasing

Increasing

Explanation:

We can change gas to liquid by decreasing the temperature and increasing the pressure.

  • Temperature is the degree of hotness or coldness of a body.
  • It is a function of how much heat it has absorbed or lost.
  • Heat causes the thermal energy of a system to increase and the particles becomes randomized.
  • Pressure is the force per unit area of particles.
  • If we decrease the temperature of gases, they have less kinetic energy and entropy reduces.
  • The will not be random.
  • Further increasing their pressure will bring them together and make them flow like liquid.
  • This phase change is often called condensation.
