## Step 1Beta particles are high-energy, high-speed electrons or positrons that are emitted by certain types of radioactive nuclei. They are a type of ionizing radiation.## Step 2There are two types of beta particles: beta-minus (β-) and beta-plus (β+). ## Step 3Beta-minus (β-) particles are high-energy electrons. They have a negative charge and almost no mass. This is because they are essentially electrons, which are subatomic particles with a negative charge and negligible mass.## Step 4Beta-plus (β+) particles are high-energy positrons. They have a positive charge and almost no mass. This is because they are essentially positrons, which are the antiparticles of electrons, with a positive charge and negligible mass.## Step 5Given the options, the correct answer is "a negative charge and almost no mass". This is because beta particles, specifically beta-minus (β-) particles, have a negative charge and almost no mass.
