Question

Which of the following is not true about beta emissions?

Difference of the atomic number by one between the old element and new element formed

Are written as 0-1e

Cannot penetrate concrete

Less penetrating than alpha emissions

Answer 1

a beta particle is just a high energy electron, so there is no change in the elements identity, i.e. no change in the number of protons

Answer 2

So which one would it be?

Answer 3

using what i said, which one do you think it is?

Answer 4

Atomic number = protons. So since aaronq already told you there's no change in protons... which answer would make the most sense?

Answer 5

B?

Answer 6

the last one:
less penetrating then alpha

Answer 7

beta particles has more penetrating ability then alpha because its has less ionising ability then alpha. Beta travels at 90% speed of light then alpha which travels at 10% speed of light.

Answer 8

The answer will be C beta particles cannot pass through concrete as they have low penetrating power the loss of beta particle causes an increase in the element's ATOMIC number by 1 and beta has more penetrating power so only C is incorrect!

Answer 9

@ArslanQureshi it can be D too because beta has high penetrating ability then alpha

Answer 10

yes it can be D too I will suggest using D because thickness of concrete is not mentioned

Answer 11

ok so.. i'm right

Answer 12

yes u r

Answer 13

it cannot penetrate concrete as it is beta emmisions are stopped by a thin sheet of lead
