The diameters of four different types of atoms are given below.

Atom A: 1.35 * 10^-7 mm; Atom B: 1.80 * 10^-7 mm; Atom C: 6.00 * 10^-8 mm; Atom D: 2.50 * 10^-8 mm
What is the order of these atoms from largest to
smallest? (1 point)

A. B;A;C;D
B. C;D;B;A
C. D;C;A;B
D. A;D;B;C

1 answer

convert all to use the same power of 10
then just compare the coefficients
If we use 10^-8 for all the numbers, then
A = 13.5 * 10^-8
and so on
