To find the value of [tex]\( Y \)[/tex] from the given table, we need to focus on the element Manganese (Mn). The relevant columns for Manganese are:
1. Number of Protons (X)
2. Mass Number
3. Number of Neutrons (Y)
4. Number of Electrons (Z)
Given:
- Manganese (Mn) has 25 protons.
- The Mass Number of Manganese is 55.
- The number of electrons in a neutral atom of Manganese is equal to the number of protons, which is 25.
The value [tex]\( Y \)[/tex] represents the number of neutrons in Manganese.
The number of neutrons can be calculated using the Mass Number and the number of Protons with the formula:
[tex]\[
\text{Number of Neutrons} = \text{Mass Number} - \text{Number of Protons}
\][/tex]
Substituting the given values:
[tex]\[
\text{Number of Neutrons (Y)} = 55 - 25 = 30
\][/tex]
So the value of [tex]\( Y \)[/tex] is [tex]\( 30 \)[/tex].
