use the periodic table to determine which of the following could be an isotope of bromine (br). check all that apply. z = 79, a = 196 z = 35, a = 79 a = 79, n = 44 z = 44, n = 44 done

Answer

Explanation:

Step1: Recall atomic number of bromine

Bromine (Br) has an atomic number $Z = 35$ from the periodic - table.

Step2: Analyze each option

  • For $Z = 79,A = 196$, since $Z=79$ is not 35, this is not an isotope of bromine.
  • For $Z = 35,A = 79$, as $Z = 35$ (atomic number of bromine), this could be an isotope of bromine.
  • For $A = 79,N = 44$, first find $Z$ using $A=Z + N$. So $Z=A - N=79 - 44 = 35$, this could be an isotope of bromine.
  • For $Z = 44,N = 44$, since $Z = 44\neq35$, this is not an isotope of bromine.

Answer:

$Z = 35,A = 79$; $A = 79,N = 44$
