Solution: Predict the charge that an aluminum ion would have.a. 5-b. 1+c. 1-d. 2+e.3+

Problem

Predict the charge that an aluminum ion would have.

a. 5-

b. 1+

c. 1-

d. 2+

e.3+

Solution

Determine the charge that an aluminum ion would have using the periodic table


Recall that when an element becomes an ion, the element tries to achieve the electron configuration of the nearest noble gas


Aluminum is located in Period 3 Group 4A where the nearest noble gas is Ne
