@Angle please help :)

Answer 5

All known elements are listed on the periodic table of elements.

Elements are all the same atoms. Those atoms that are identical = element.

Electron is a part of an atom. Atoms are made up of protons, neutrons, and electrons.

Answer 6

so #1 is D?

Answer 7

@Angle

Answer 8

electron + proton + neutron = atom

atom + atom + atom = element

D says element + element = electron, which is not true

Answer 9

oh ok, so C

Answer 10

I just said: atom + atom + atom = element

C says element + element + element = atom, which is still not true

Answer 11

I said: "All known elements are listed on the periodic table of elements."

If there are infinitely many elements, would you be able to list all of them?
So B is not true either

Answer 12

ohhh omg that makes sense its A! @Angle

Answer 13
