How small atom partical are?​
ElenaW [278]

Atoms of particles are so small that they cannot be divided further by any physical means.

<h3>What are atoms?</h3>

According to John Dalton, atoms are the smallest, indivisible particles of elements.

However, it was later found out that chemically, atoms consist of protons, neutrons, and electrons.

Thus, the indivisibility of atoms that John Dalton was referring to must be that of physical division.

In other words, the particles of atoms are so small that dividing them further using physical means is absolutely impossible.

Select the expression that is equivalent to 3x105+5x108.
VashaNatasha [74]
When you're dealing with scientific notation (especially when you use an order of operations such as adding on it), it's important to know that you cannot add 10^2 to 3 (for example).

(3 x 10^5) + (5 x 10^8)

When adding exponents, you're only adding the exponents together and not changing the original number (10).

5 + 8 = 13

We now have a sum of 3x5 x10^13

Multiply 3 by 5 to get your new expression.

3 x 5 = 15

15 x 10^13 is what we're left with.

Your answer is A.)

I hope this helps!
