Question

Can someone help me real fast?

Answer 1

Which of the following best describes an ion?


An element with the same number of protons but different number of electrons.
An element with the same number of neutrons but different number of electrons.
An element with the same number of protons but different number of neutrons.
An element with the same number of electrons but different number of protons

Answer 2

anyone?

Answer 3

Current produced in a wire by a magnet is called:

electromagnetic conduction.
electromagnetic induction.
pseudo-magnetic construction.
neo-magnetic reduction.
electromagnetic spectrum.

Answer 4

Is the second question electromagnetic induction?

Answer 5

yes it is

Answer 6

the first question is not clear - same number of whatever, compared to what ?

Answer 7

idk that is how the question is written

Answer 8

whatever best describes it not sure either @ProfBrainstorm

Answer 9

an ion is an atom that has gained or lost electrons, compared to the neutral atom

Answer 10

so would the answer be b?

Answer 11

a and b are consistent with the definition of an ion

Answer 12

I gotta choose one still am not sure yet

Answer 13

re ProfBrainstorm:
"an ion is an atom that has gained or lost electrons, compared to the neutral atom" - Correct. An Ion is a element with a different charge because of more more or less electrons. The Neutron has nothing to do with the charge so any reference to it would not be the best answer. An element that changed the numbers of proton would not be the same element. A is the correct answer.

Answer 14

yes, you make a fair point @mstoldegon - although when one thinks about the ionisation of an atom there isn't any change to the nucleus, be it the number of protons or neutrons
