Would electrons move from higher potential to lower potential or vice versa?

Do free electrons travel to region of higher potential or lower potential?

General instruction same as in chapter 1. Assertion: Electrons move away from a low potential to high potential region. Reason:Because electrons has negative charge.

Define electric potential at a point. When kept in an electric field, does a proton move form lower to higher potential or from higher to lower potential region?

When an electron falls from a higher energy to a lower energy level, the difference in the energies appears in the form of electromagnetic radiation. Why cannot it be emitted as other forms of energy?

STATEMENT-1: We cannot add the electrode potential in order to get electrode potential of third electrode if no. of moles of electrons exchanged are not same. STATEMENT-2: Electrode potential is an extensive property

Give two examples where there is transfer of matter from terrestrial to aquatic ecosystem or vice-versa.

The electrode with higher reduction potential acts as a…..

Bohr model is a system consisting of small, dense nucleus surounded by orbting electrons. The electrons travel in defined circular orbits around the nucleus for which orbital angular momentum is an itnegral multiple of h/(2pi) . While rotating in allowed orbits the electrons does not raidate energy. Electromagneitc radiations are emitted when the electrons jumps from a higher orbit (E_(n_i)) to a lower orbit (E_(n_f)) When an electron jumps from higher to lower orbit energy is:

60 J of work must be done to move electric charge equal to 5 C from a point, where potential is +20V to another point, where potential is V volt. Find the value of V.
