## anonymous one year ago Which of the following statements is true about beta particles? Question 11 options: When a radioactive atom emits a beta particle, the overall mass number stays the same. The penetrating power of a beta particle is less than that of an alpha particle. A beta particle is symbolized by the Greek letter γ. A beta particle is the same as a helium nucleus. When a radioactive atom emits a beta particle, the original atom's atomic number decreases by two.

i think its d

3. hartnn

beta particle is an electron, (not helium nucleus) it will increase atomic number by 1 represented by $$\beta$$

so its b

5. hartnn

penetration power of beta particle is more than alpha mass number does not get affected by beta emision

o it is d

7. hartnn

the overall mass number stays same! so it is A :)

a
