the table below gives some characteristics of element y. characteristics of element y values mass number 11 number of neutrons in a single atom 6 average atomic mass (grams/mole) 10.81 what is the identity of element y? c b na s
Answer
Explanation:
Step1: Calculate number of protons
The mass - number ($A$) is the sum of protons ($p$) and neutrons ($n$), i.e., $A=p + n$. Given $A = 11$ and $n=6$, we can find $p$ as $p=A - n$. So, $p=11 - 6=5$.
Step2: Identify the element
The number of protons determines the atomic number ($Z$) of an element. An element with atomic number $Z = 5$ is Boron (B).
Answer:
B. B
