this is a bohr model of an atom or ion. select the nuclear notation that represents this atom or ion. refer to a periodic table.
Answer
Answer:
B. $_{8}^{16}O^{2 - }$
Explanation:
Step1: Count protons
There are 8 protons in the nucleus, so the atomic number (sub - script) is 8.
Step2: Count protons and neutrons
There are 8 protons and 8 neutrons, so the mass number (super - script) is $8 + 8=16$.
Step3: Determine charge
There are 10 electrons and 8 protons, so the ion has a charge of $2 -$.
Step4: Identify element
The element with atomic number 8 is oxygen (O). So the nuclear notation is $_{8}^{16}O^{2 - }$.
