To determine the answers to the questions in Column A, we need to analyze the given nuclear reaction and understand the concepts related to atomic mass, atomic number, the symbol of an atom, and types of decay.
Let's start by analyzing the given reaction and breaking it down:
- The original atom has an atomic number of 88 and an atomic mass of 224.
- The product of this nuclear reaction is a new atom.
Now, let's answer each question:
1. What is the atomic mass of the new atom?:
To determine the atomic mass of the new atom, we need to look at the conservation of mass in a nuclear reaction. In this case, the atomic mass of the original atom (224) is equal to the atomic mass of the new atom. Therefore, the atomic mass of the new atom is also 224.
2. What is the atomic number of the new atom?:
Similar to the atomic mass, the atomic number is also conserved in a nuclear reaction. The original atom has an atomic number of 88, so the new atom will also have an atomic number of 88.
3. What is the symbol of the new atom?:
To determine the symbol of the new atom, we need to know the element corresponding to an atom with an atomic number of 88. Looking at the periodic table, we find that the element with an atomic number of 88 is radium, which has the symbol Ra.
4. What type of decay is demonstrated here?:
Based on the given options for the type of decay (a-e), we can see that the symbol of the original atom before the reaction is Th (Thorium), and the symbol of the new atom after the reaction is Ra (Radium). This indicates that the decay demonstrated here is alpha decay (option f), where an alpha particle (He-4 nucleus) is emitted from the original atom, resulting in a new atom.
Therefore, the answers to the questions in Column A are:
1. What is the atomic mass of the new atom?: 224
2. What is the atomic number of the new atom?: 88
3. What is the symbol of the new atom?: Ra
4. What type of decay is demonstrated here?: Alpha Decay
