When calcium forms an ion, it loses its two valence electrons and becomes a calcium ion with a 2+ charge. In that case the highest energy level occupied by the calcium ion's electrons in its ground state would be the third energy level.
Depreciation involves the reduction in the value of a quantity
The rate of depreciation is about 13%
<h3>How to determine the equation</h3>
From the question, we have the following ordered pairs
(x,y) = {(0,9000) and (5,4500)}
The depreciation equation is represented as:

At (0,9000), we have:


At (5,4500), we have:

This gives

Solve for b^5

Take the 5th roots

So, we have:


The rate (r) is then calculated as:

This gives



Express as percentage

Hence, the rate of depreciation is about 13%
