To answer these questions, we need to understand the given nuclear reaction and its components.
In the given nuclear reaction:
252/99 Es ----> 0/-1 e + a/z X
We have the following components:
- 252/99 Es: This is the starting atom, where the numerator represents the atomic mass (252) and the denominator represents the atomic number (99). Es is the symbol for the element.
- 0/-1 e: This represents an electron (e) with 0 atomic mass (0) and -1 atomic number (-1). The negative sign indicates that this is a beta particle (electron) with a negative charge.
- a/z X: This represents the new atom that is formed. "a" represents an alpha particle, which consists of 2 protons and 2 neutrons, giving it an atomic mass of 4 and an atomic number of 2. "z" represents the atomic number of the new atom. Since the new atom is not specified in the question, we need to determine its atomic number and symbol.
Now let's answer the questions:
1. What is the atomic mass of the new atom?
The atomic mass of the new atom is 4.
2. What is the atomic number of the new atom?
The atomic number of the new atom is 2.
3. What is the symbol of the new atom?
Since we don't have the specific element mentioned in the given reaction, we cannot determine the exact symbol. However, based on the atomic number (2), we know that it belongs to the element with atomic number 2. The element with atomic number 2 is helium (He). So, the symbol of the new atom can be considered as He.
4. What type of decay is demonstrated here?
The given nuclear reaction represents alpha decay. In alpha decay, an alpha particle (2 protons and 2 neutrons) is emitted from the nucleus of the starting atom.
Matching the answers with the options given in Column B:
1. Atomic mass of the new atom: a. 100
2. Atomic number of the new atom: g. 99
3. Symbol of the new atom: i. Fm
4. Type of decay demonstrated: f. Alpha Decay
Hence, the correct answers are:
1. Atomic mass of the new atom: a. 100
2. Atomic number of the new atom: g. 99
3. Symbol of the new atom: i. Fm
4. Type of decay demonstrated: f. Alpha Decay
