What is thought to happen when electrons jump from a higher level to a lower level

Chemistry

AURORKA [14]3 years ago

As the electrons move away from the nucleus, it gains energy and becomes less stable. When electron jumps from lower energy level to higher energy level, it gains energy from surroundings which is known as absorption of energy. When an electron jumps from higher energy level to lower energy level, it releases energy which is known as emission of energy. Note that the electron can absorb or emit only that much amount energy which is equal to energy difference between two levels.

Depression what are the effects to the brain
oksian1 [2.3K]
Depression can affect a person psychologically, it also has the potential to affect physical structures in the brain. These physical changes range from inflammation and oxygen restriction, to actual shrinking. Depression can impact the central control center of nervous system. Depression can cause amygdala to enlarge. This is a part of the brain associated with emotional responses. When amygdala becomes larger and more active, it causes sleep disturbances, changes in activity levels, and changes in other hormones.

BRAINLIESTTT ASAP!! PLEASE HELP ME :)
VladimirAG [237]

Answer:

Chlorine takes electrons from potassium in the reaction.

Explanation:

2K + Cl₂ ⟶ 2KCl

The KCl is an ionic solid.

It consists of K⁺ and Cl⁻ ions that are formed by the transfer of an electron from K to Cl.

The chlorine takes electrons from potassium, and Gain of Electrons is Reduction.

At the same time, potassium loses electrons to chlorine, and Loss of Electrons is Oxidation.

Both oxidation and reduction are occurring, so this is an oxidation-reduction reaction.

2.50 L of a gas at standard temperature and pressure is compressed to 575 mL. What is the new pressure of the gas
vfiekz [6]

Answer:

4.35 atm

Explanation:

According to the information given;

  • Initial volume of the gas, V₁ is 2.50 L
  • Initial pressure of the gas is standard pressure P₁, normally 1 atm
  • New volume of the gas, V₂ is 575 mL

We are required to determine the new pressure of the gas, P₂ ;

To answer the question, we are going to use the Boyle's law, that relates pressure and volume at constant temperature.

According to Boyle's law;

P₁V₁ = P₂V₂

Therefore, to determine the new pressure, P₂, we rearrange the formula;

New pressure, P₂ = P₁V₁ ÷ V₂

Thus;

P₂ = ( 1 atm × 2.50 L) ÷ 0.575 L

    = 4.3478 atm

     = 4.35 atm

Therefore, the new pressure of the gas is 4.35 atm

How many electrons in an atom can have each of the following quantum number or sublevel designations?
storchak [24]

10 electrons in an atom can have each of the 3d quantum number or sublevel designations.

<h3>What are four quantum numbers?</h3>

Quantum numbers are used to characterize the values of conserved quantities in a quantum system's dynamics in both quantum physics and chemistry.

1) The "n" sign refers to the principal quantum number. It shows how many shells there are.

2) The "l" sign indicates the azimuthal quantum number. It gives the form of the orbitals and their angular momentum. 0 to n-1 make up its range.

3) "m_{l}" stands for the magnetic quantum number. It serves as a cue for spatial orientation. The range of it is -l to +l.

4) Spin quantum number, represented by the symbol "m_{s}". It shows how the electron is spinning.
