The Electrolyte when dissolved in polar solvent like H₂O dissociates into positive specie called Cation and a negative specie called Anion. When an electric current is applied to Electrodes dipped in solution of electrolyte, the cations move toward the negative electrode while anions move towards positive electrode. At electrodes the exchange of electrons take place.
Result:
So, the passage of current in electrolyte solution is due to both Cations and Anions.
When an atom gains an electron it becomes a negatively charged ion. When an atom looses an electron it becomes positively charged because the number of positively charged protons.
Hope this helps
Answer:
All the above.
Explanation:
Energy is defined as the ability to do work. And changes in every occur in all changes of matter. Energy is neither created nor destroyed in these changes, but simply changes from on form to another.
Answer:
The three main atomic particles are protons, neutrons and electrons. The atomic number of an atom identifies the number of protons in the atom. This is the defining characteristic of an element. An atom can gain or lose neutrons or electrons while retaining its elemental identity.
