To determine the answers to the questions for the given nuclear reaction, we can use the information provided in the reaction itself. Let's go through each question step by step:
1. What is the atomic mass of the new atom?
In the nuclear reaction, the original atom (Cm) is undergoing decay and producing two new particles, a helium atom (He) and an unknown atom (X). Since the atomic mass on the left side (247) should be conserved, it must also be the atomic mass of the new atom. Therefore, the atomic mass of the new atom is 247.
2. What is the atomic number of the new atom?
The atomic number is determined by the number of protons in the atom. In the given reaction, the original atom (Cm) has 96 protons. When it undergoes decay and loses one He (helium) atom, the number of protons decreases by 2. Therefore, the atomic number of the new atom will be 96 - 2 = 94.
3. What is the symbol of the new atom?
Considering that the initial atom is Cm, and the new atom has an atomic number of 94, the symbol of the new atom can be determined by looking at the periodic table. In this case, the symbol for the new atom is Pu (Plutonium).
4. What type of decay is demonstrated here?
Looking at the reaction, we can see that the original atom (Cm) is decaying and producing a helium atom (He). This type of decay is called alpha decay, which involves the emission of an alpha particle (a helium nucleus) from the nucleus.
Now we can match the answers to the options provided in Columns B:
1. c. 251
2. e. 94
3. k. Pu
4. n. Alpha Decay
