To identify element [tex]$Y$[/tex], we need to determine its atomic number, which is equivalent to the number of protons in a single atom of the element. The atomic number uniquely identifies the element in the periodic table.
We are given the following information about element [tex]$Y$[/tex]:
- Mass number = 11
- Number of neutrons = 6
The mass number of an element is the sum of its protons and neutrons:
[tex]\[ \text{Mass number} = \text{Number of protons} + \text{Number of neutrons} \][/tex]
Using the given values:
[tex]\[ 11 = \text{Number of protons} + 6 \][/tex]
To find the number of protons (which is the atomic number), we subtract the number of neutrons from the mass number:
[tex]\[ \text{Number of protons} = 11 - 6 \][/tex]
[tex]\[ \text{Number of protons} = 5 \][/tex]
An element with 5 protons corresponds to Boron (B) in the periodic table.
Therefore, the identity of element [tex]$Y$[/tex] is Boron ([tex]$\text{B}$[/tex]).
