WHY POSITIVE IONS ARE NOT FREE TO MOVE ??
Positive ions may be free to move depending on their state of matter. The simpliest example is the hydrogen ion (H+). More simply put a proton. Other examples would be gaseous metals that are at a high enough temperature to have 1 or more electrons removed.
ANSWER IS NOT CORRECT !! CAN ANYONE HERE WHO CAN ANSWER DIS QUESTION QUESTION CORRECTLY !!!!!!!!!!!!!!!!!!
PLZ EXPLAIN ME MORE !!!
This is because the positive ions are the protons and these protons are present in the nucleus of the cells and the nucleus strongly attracts positive as well as negatine ions which are the electron towards it but the proton is near the nucleus therefore it is not free to move while the electrons moves round the orbit which is a bit far from the nucleus therefore attraction is less and it is free to move.
