Problem 86P

Predict the ion formed by each element.

(a) F

(b) N

(c) Mg

(d) Na

Step-by-Step Solution:

Solution 86P

Here, we are going to identify the ion formed by each of the given elements.

Step 1:

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.

Step 2:

The type of ion formed by an atom depends on the electronic configuration(distribution of electrons in the various shells) of the atom. Atoms always try to gain 8 electrons in their outermost shell(Octet rule) and attains nearest noble gas configuration. So, in order to complete this octet, they gain or lose electrons and form ions.
