To determine which process is most likely to make polonium stable, we need to look at its properties and the different types of decays.
Polonium is known for having a large, unstable nucleus. One way to reach stability is by undergoing radioactive decay, which involves the release of particles or energy from the nucleus.
Let's review the four options mentioned:
1. Beta-plus decay: This process occurs when a proton in the nucleus changes into a neutron, emitting a positron (a positively charged electron) and a neutrino. Polonium does not have excess protons, so this type of decay is unlikely to occur.
2. Alpha decay: This process involves the emission of an alpha particle, which consists of two protons and two neutrons. Polonium can undergo alpha decay to become a more stable element.
3. Gamma decay: Gamma decay refers to the release of gamma rays, which are electromagnetic radiation. Unlike alpha or beta decay, gamma decay does not change the composition of the nucleus. It only releases energy and helps in reaching a lower energy state. While it does not directly stabilize polonium, it may accompany other types of decay as a part of the process.
4. Beta-minus decay: This process occurs when a neutron in the nucleus changes into a proton, emitting an electron (beta particle) and an antineutrino. Polonium does not have excess neutrons, so this type of decay is also unlikely to occur.
Based on the options presented, alpha decay, in which polonium emits an alpha particle, is the most likely process for polonium to undergo in order to become stable.
