How Does Moving an Electron Affect Proton-Electron System Energy?

The total energy of the system (electron + proton + electric fields) is still conserved. In summary, the conversation discusses the movement of an electron from a distance r from a proton to infinity, which requires energy. The energy of the system is defined as zero, but this is an arbitrary definition. The energy pumped into the system is now potential energy and the law of conservation of energy is not violated as the total energy of the system is still conserved.

Suppose an electron initially present at distance r from the proton is moved away to infinity,the energy of the system is taken to be zero.If it is so where does the energy pumped into shift away the electron goes and thus the law of conservation of energy is violated

You need energy to do this.

the energy of the system is taken to be zero
Ok, this is an arbitrary definition of the energy. Fine.

If it is so where does the energy pumped into shift away the electron goes
It is now potential energy. You can even calculate it, if you integrate over the energy stored in the electric fields around the charges and compare this to the field configuration with the electron at distance r.

and thus the law of conservation of energy is violated
No. You increase the energy of the electric fields.
 

1. What is a proton electron system energy?

The proton electron system energy, also known as the electrostatic potential energy, is the potential energy that exists between a proton and an electron due to their opposite charges. It is a fundamental concept in chemistry and physics, as it helps explain the behavior of atoms and molecules.

2. How is the proton electron system energy calculated?

The proton electron system energy can be calculated using the Coulomb's law, which states that the force between two point charges is directly proportional to the product of their charges and inversely proportional to the square of the distance between them. The formula for calculating the energy is E = k(Q1Q2)/r, where k is the Coulomb's constant, Q1 and Q2 are the charges of the proton and electron, and r is the distance between them.

3. What is the unit of measurement for proton electron system energy?

The unit of measurement for proton electron system energy is joules (J). However, in chemistry, it is often expressed in electron volts (eV) or kilojoules per mole (kJ/mol).

4. How does the proton electron system energy affect chemical reactions?

The proton electron system energy plays a crucial role in chemical reactions, as it determines the stability and reactivity of atoms and molecules. When two atoms come together to form a bond, the energy released or absorbed is a result of the change in the proton electron system energy.

5. Can the proton electron system energy be changed?

Yes, the proton electron system energy can be changed by altering the position or the charge of the proton and electron. This can be achieved through external forces, such as applying an electric field, or through chemical reactions, where the movement of electrons can lead to changes in the proton electron system energy.
