Question

The diameter of four different types of atoms are given below.
Atom A:1.35x10^-7 mm; Atom B:1.80x10^-7 mm; Atom C:6.00x10^-8 mm; Atom D:2.50x10^-9 mm
What is the order of these atoms from largest to smallest?

Answer 1

The order of these atoms from largest to smallest is:

Atom B > Atom A > Atom C > Atom D

To see this, we can convert all of the diameters to meters for easier comparison:

Atom A: 1.35 x 10^-7 mm = 1.35 x 10^-10 m
Atom B: 1.80 x 10^-7 mm = 1.80 x 10^-10 m
Atom C: 6.00 x 10^-8 mm = 6.00 x 10^-11 m
Atom D: 2.50 x 10^-9 mm = 2.50 x 10^-12 m

We can see that Atom B has the largest diameter, followed by Atom A, then Atom C, and finally Atom D with the smallest diameter.
