Question

show the different ions and their symbols ​

Answer 1

Answer:

There are m resistor each of resistance R. First they all are connected in series and equivalent resistance is X. Now they are connected in parallel and equivalent resistance is Y. What is the ratio of X and Y?

Solution

Answer 2

• The positively or negatively charged species is known as Ions.
• The positively charged ions are called cations while negatively charged species are known as anions.
• Some positively charged ions are:

         Sodium-ion                Na⁺

         Potassium- ion            K⁺

         Copper- ion                Cu⁺

         Ammonia                    NH₄⁺

         Magnesium                 Mg⁺²

         Calcium                       Ca⁺²

         Aluminium                   Al⁺³

          Iron                              Fe⁺³

• Some negatively charged ions are:

         Chloride                        Cl⁻

         Hydroxide                     OH⁻

         Bromide                         Br⁻

         Carbonate                    CO₃⁻²

         Sulphate                       SO₄⁻²

          Nitride                           N⁻³

         Phosphate                    PO₄⁻³
