Predict the ion formed by each element.
Here, we are going to identify the ion formed by each of the given elements.
Ions are formed by the loss or gain of electrons. An ion is a charged particle and can be negatively or positively charged. A negatively charged ion is called an ‘anion’ and is formed by gain of electrons and the positively charged ion is called a ‘cation’ and is formed by the loss of electrons.
The number of charges in the ion indicate the number of electrons lost or gained.
For example, Na+ has one positive charge. Here, the positive charge indicates loss of electron and the number of charge (1) indicates loss of one electron.
