To answer the questions based on the nuclear reaction provided, we need to establish the nature of that reaction. Since the reaction is not explicitly given, let’s infer from typical nuclear decay processes, particularly focusing on alpha decay, beta decay, and gamma decay.
Assuming we have an alpha decay scenario:
-
What is the atomic mass of the new atom?
- In an alpha decay, an alpha particle (which consists of 2 protons and 2 neutrons) is emitted. The atomic mass of the new atom would be the original mass minus 4 (2 from the protons and 2 from the neutrons).
- Assuming a starting atom with mass 228 (like Radium-228, Ra), the new atomic mass would be: 224.
- Answer: l. 224
-
What is the atomic number of the new atom?
- The atomic number decreases by 2 in alpha decay due to the loss of 2 protons. If we start with 88 (like Ra), it decreases to:
- Answer: j. 86
-
What is the symbol of the new atom?
- Since we started with Radium (Ra) which has an atomic number of 88, the new symbol after losing 2 protons (changing atomic number to 86) corresponds to Radon, which is denoted as Rn.
- Answer: m. Rn
-
What type of decay is demonstrated here?
- Given that we established a loss of alpha particles in the above steps, this reaction demonstrates alpha decay.
- Answer: e. Alpha Decay
Summary of Answers:
- Atomic mass of the new atom: l. 224
- Atomic number of the new atom: j. 86
- Symbol of the new atom: m. Rn
- Type of decay: e. Alpha Decay
