Answer 2

a. (a) and (b) are correct, they are electrons and they are deflected toward the positive electrode.

• B particles or Beta particles are high energy, high-speed electrons (B-) or positrons (B+) that are ejected from the nucleus by radionuclides during a form of radioactive decay called beta-decay. This usually occurs when there are too many neutrons trying to achieve stability.
• These particles have a mass of half of one-thousandth of the mass of a proton and are said to carry either a single negative or positive charge. They lose energy quickly through interaction with matter and move along a haphazard path.
• Beta-particles are less ionizing than alpha-particles and can travel through the air and through skin and tissue. Sufficient intensity to beta radiation can cause burns and can damage internal cells and organs if they are inhaled or ingested.
• The positive electrode is the electrode with a higher potential than the negative electrode. During discharge, it becomes a cathode, and the negative electrode becomes an anode. During charge, the positive becomes an anode and the negative electrode becomes a cathode.
