Answer to Problem 9STP

B.b

Explanation of Solution

B. magnesium fluoride has three atoms - one magnesium and two fluorine atoms. Two fluorine atoms are attached to the magnesium atom. The given figure shows different size and colors. Option B has three atoms which attached to each other with larger central atom and two atoms are the same in color.

Conclusion

The incorrect options are as follows:

A. a

Figure a has different atoms that attached one another.

C. c

Figure c has different atoms and two identical atoms that attached one another.

D. both a and b

Both figure a has different atoms.
