Chapter 17, Problem 7RAT

To determine

The correct option for the statement “How strontium and calcium are similar and why strontium can be deposited in bone tissues.”

Answer to Problem 7RAT

The correct option for the statement “How strontium and calcium are similar and why strontium can be deposited in bone tissues.” is an option (b).

Explanation of Solution

The periodic table has a certain arrangement of elements in the horizontal periods and the vertical groups. The groups are basically the vertical arrangement of atoms. In a group, atoms usually show the similar chemical properties.

The group $2$ of the periodic table is also known as alkaline earth metal where the element calcium (with atomic symbol-$\text{Ca}$ and having atomic number $20$) has its importance and existence in bone tissues. Another element strontium (with atomic symbol-$\text{Sr}$ and having atomic number $38$) of group $2$ in the periodic table shows similar chemical nature and behavior with that of calcium.

Thus, strontium tends to accumulate in place of calcium in the bone tissues due to the same chemical properties as they belong to the same group in the periodic table.

Conclusion:

Therefore, the correct option is an option (b).
