The diameters of four different atoms are shown below.
Atom A: 6.35 x 10^-7
Atom B: 1.80 x 10^-6
Atom C: 2.00 x 10^-7
Atom D: 2.50 x 10^-8
IT says to list them from LARGEST to SMALLEST.
I know what i have to do, but not sure where to start, like what i mean is, i had a problem similar to this, except with positive exponents instead of negative, and i would figure out the power of 10, then multiply it by the decimal, then write down the answer for each brand of phones i think it was?, and then listed them from highest to lowest. but for this problem, i'm just not sure that same method will work. Can someone please help?

Read And Answer Carefully, I Got A 25/25. You're Welcome Babes!!
You cannot compare apples and oranges, so
Atom A: 6.35 x 10^-7 = 63.5 x 10^-8
Atom B: 1.80 x 10^-6 = 180 x 10^-8
Atom C: 2.00 x 10^-7 = 20.0 x 10^-8
Atom D: 2.50 x 10^-8 = 2.50 x 10^-8
Now, since they are all apples. Can you order
63.5, 180, 20, 2.5 ???
you can best compare them if you make sure they all use the same power of 10. If we express them all in terms of 10^-8, we would have
6.35 x 10^-7 = 63.5 x 10^-8
do the others, and then it will be very easy to order them.

To list the atom sizes from largest to smallest, you need to compare their diameters. The given numbers are expressed in scientific notation, with the diameters written in meters.
The general principle for comparing numbers in scientific notation is to compare the decimal part after removing the power of 10.
Let's compare the atoms using this method:
1. Atom B: 1.80 x 10^-6
2. Atom A: 6.35 x 10^-7
3. Atom C: 2.00 x 10^-7
4. Atom D: 2.50 x 10^-8
To compare the atoms, you can ignore the power of 10 and only focus on the decimal part:
1. Atom B: 1.80
2. Atom A: 6.35
3. Atom C: 2.00
4. Atom D: 2.50
Now you can see that Atom A has the largest diameter (6.35), followed by Atom B (1.80), Atom C (2.00), and Atom D (2.50). Hence, the correct order from largest to smallest is Atom A, Atom B, Atom D, and Atom C.
Remember, when comparing numbers in scientific notation, it is crucial to focus on the decimal part while ignoring the power of 10.
