To determine the answers to the questions in Column A, we need to understand the given nuclear reaction:
223/87 Fr ----> 0/-1 e + a/z X
1. What is the atomic mass of the new atom?
The atomic mass (A) is the sum of the protons and neutrons in the nucleus. In the reaction, an alpha particle (a) and a beta particle (e) are emitted, which means the atomic number (Z) decreases by 2 and the atomic mass decreases by 4. Therefore, the atomic mass of the new atom can be calculated as: 223 - 4 = 219.
2. What is the atomic number of the new atom?
The atomic number (Z) represents the number of protons in the nucleus. In this reaction, an alpha particle (a) is emitted, which means the atomic number decreases by 2. Thus, the atomic number of the new atom is: 87 - 2 = 85.
3. What is the symbol of the new atom?
The symbol of an atom is determined by its atomic number and atomic mass. In this case, the atomic number of the new atom is given as 85, so we look for the element with atomic number 85 on the periodic table. The element associated with atomic number 85 is astatine (At). Therefore, the symbol of the new atom is At.
4. What type of decay is demonstrated here?
The decay process can be determined by observing the particles emitted. In this case, an alpha particle (a) is emitted, which consists of two protons and two neutrons. This type of decay is known as alpha decay.
So, the answers to the questions in Column A would be:
1. d. 224
2. j. 85
3. k. At
4. a. Alpha Decay
