Need help...
Silver (Ag) has 47 protons in each atom. Based on this information, which of the following also describes an atom of silver?
A-It has no neutrons.
B-It has 23 neutrons and 24 electrons.
C-It has 47 electrons.
D-It has a total of 94 neutrons and electrons.

Answer 1

well what choices can you eliminate if you're given ONLY the number of PROTONS

Answer 2

Well you can definitely eliminate answer A, because if the answer was A, that would be like saying just because there are protons, there are no neutrons, which makes no sense at all

Answer 3

and elements have neutrons of course, while they must have a certain number of protons to be a specific element, so you can eliminate that answer

Answer 4

sorry i'm dyslexic

Answer 5

So now we know that the number of protons defines the element. Now let's also keep in mind that the number of protons+the number of neutrons equals the mass. The number of neutrons itself is NOT the entire mass. So what do you think about answer B? could that make sense based on this explanation?

Answer 6

also, yes, I did eliminate answer A, we didn't eliminate anything else yet

Answer 7

I think B would work.

Answer 8

thanks

Answer 9

electrons do not play a part in the mass, they may seem similar to protons. However, it's only a combination of protons and neutrons that make up the mass, the electrons do not play any role in this

Answer 10

so you have to be very careful there with chemistry terminology

Answer 11

how many electrons do you think this element might have? this will definitely help answer the question

Answer 12

i already submitted

Answer 13

my teacher helped

Answer 14

okay, well sorry I couldn't answer faster, I was just trying to explain everything so you would understand before giving a straight answer

Answer 15

you are fine

Answer 16

thank you for your help

Answer 17

just keep in mind for the future, the number of electrons and protons will always be the same, and the number of protons and neutrons affect the mass
