Question

Which of the following represents an ion?

A.a particle having 14 protons, 14 neutrons, and 14 electrons
B.a particle having 9 protons, 9 neutrons, and 10 electrons
C.a particle having 19 protons, 21 neutrons, and 19 electrons
D.a particle having 1 proton, 3 neutrons, and 1 electron

Answer 1

I can help you with this question, if you help me! :) Do you know what an ion is? Do you have any ideas as to what is NOT the answer?

Answer 2

I can help you out if you're stuck. Look at choice A. It is wrong, totally wrong. Do you know why it is wrong?

Answer 3

Because there all the same?

Answer 4

Yes! You're onto something. I'm guessing you might need a little help understanding what an ion is?

Answer 5

Yeah i do..

Answer 6

Which of the following ideas is supported by Darwin's observation of local variation among tortoises in the Galapagos Islands? (1 point)
artificial selection
adaptation
acquired characteristics
tendency towards perfection

Answer 7

I think its "Adaptation"

Answer 8

cool but i need to know for sure if that is right

Answer 9

Okay then. An ion is an electrically charged atom. It is electrically charged because it has either gained an electron, or lost one.

Answer 10

okay i think adaption is the right answer to

Answer 11

well the answer to the question "What idea is supported by Darwin's observation of local variation among toritoises in the galapagos islands?" is Adaption

Answer 12

okay cool

Answer 13

So, that eliminates choice D. The 1 electron (negative charge) and the one proton (positive charge) cancel each other out. That means that choice D is a neutrally-charged atom, NOT an ion. Do you get it now?

Answer 14

Kinda..

Answer 15

Well, let's make sure. Do you see any other choice that can be eliminated? You have choices B and C to pick from now.

Answer 16

In order to have an ion, you can only have these options:

a) an ion with a negative electric charge. That means more electrons than protons. example: 1 proton, 1 neutron, and 2 electrons.
b) an ion with a positive electric charge - more protons than electrons. example: 2 protons, 1 neutron, and 1 electron.

If you have an ion, you CANNOT have:

a) An atom with equal charge: 1 proton, 1 neutron, 1 electron
or b) an atom with an equal amount of protons and electrons: 1 proton, 5 neutrons, and 1 electron.

Now do you understand it?

Answer 17

Maybe "B"

Answer 18

You're absolutely right! :D "B" is the answer. It is an ion. So do you get it now?

Answer 19

Yea i think so.. Thanks

Answer 20

You're welcome! Let me know if you have anymore questions! :) I am glad I was able to help you today.
