A beta particle is the same as __ a positron a proton a helium nucleus an electron

## Step 1<br />A beta particle is a type of subatomic particle that is emitted during a type of radioactive decay known as beta decay. <br /><br />## Step 2<br />There are two types of beta particles: beta-minus (β-) and beta-plus (β+). <br /><br />## Step 3<br />A beta-minus particle is an electron, while a beta-plus particle is a positron. <br /><br />## Step 4<br />A positron is the antiparticle of an electron, meaning it has the same mass as an electron but opposite charge. <br /><br />## Step 5<br />Therefore, a beta particle can be either an electron or a positron, depending on the type of beta decay. <br /><br />## Step 6<br />In this question, the correct answer is "a positron" because it is the same as a beta particle in the context of beta-plus decay.
