Question

The emission of a Beta particle has the effect of...?
- Decreasing mass by one unit
- Increasing mass by one unit
- No change in mass
- Adding a proton to the nucleus
- Adding a proton of zero mass to the nucleus

CAN BE MORE THAN ONE

Answer 1

Beta particles have the same weight as electrons but are positively charged, electrons way very very very very little relative to protons and neutrons

Answer 2

No change in mass is of the choices

Answer 3

"An unstable atomic nucleus with an excess of neutrons may undergo β− decay, where a neutron is converted into a proton"

Answer 4

thus the process of beta decay doesn't change the mass of the atom and converts a neutron to a proton

Answer 5

The positive charge I'm not sure of I read about them being positive when I was researching PET scans

Answer 6

which ones though. i got the first one, third and second

Answer 7

They can be positive or negatively charge

Answer 8

- No change in mass -> Beta particles weight about the same or the same as an electron which ways like nothing compared to a proton or a neutron so it doesnt effect the weight of the atom losing a beta particle

- Adding a proton to the nucleus -> A neutron being converted to a Proton releases the Beat particle Neutrons weight the same as Protons thus there is not net change in the atoms mass

The last one makes no sense Protons have weight thus it would be impossible to say that you are adding a proton with no weight It would be like me saying I took off my shirt Now I weight nothing.

Answer 9

Neutrons dont weight exactly the same as protons but so close that they basically weight the same

Answer 10

there's one you're missing though.

Answer 11

Hope this helps just check out:

Answer 12

No there isn't no other options make sense

Answer 13

yeah there is. i'm getting partial credit.

Answer 14

decreasing mass by one unit?

Answer 15

No that makes no sense Beta particles weight nothing

Answer 16

alright. do you know how to complete radioactive decay problems?

Answer 17

Na man this is all from vague memory :| are you sure I'm missing one?

Answer 18

also I just did some reading just now

Answer 19

stuff like this:

Answer 20

No sorry can't help you my knowledge of radioactive decay is finite I'm a biochemist :|

Answer 21

alright. thanks anyways c:

Answer 22

no problem :) what program are you in to be learning stuff like this?

Answer 23

if I may query

Answer 24

Alpha Omega Academy. online school

Answer 25

what was yalls answer to that?:(

Answer 26

who is yalls?

Answer 27
