    Beta particles are more penetrating than alpha particles, thus alpha particles are less penetrating than beta emissions

    But be-careful, the questionwants to know "Which of the following is \(\color{red}{NOT~TRUE}\) about alpha emissions."

    Alpha emissions are generally more common in elements with atomic # greater than 83 (>83)

    I suggest doing a research regarding Alpha emissions. If you don't have lessons already planned by your instructors with you, then try the search engine.
