select the correct answer from each drop - down menu. an element has an atomic mass number of 16 and an atomic number of 7. the element has protons and neutrons.

Answer

Answer:

The element has 7 protons and 9 neutrons.

Explanation:

Step1: Recall proton - atomic number relation

The atomic number is equal to the number of protons. Given atomic number = 7, so number of protons = 7.

Step2: Calculate number of neutrons

The atomic mass number is the sum of protons and neutrons. Let the number of neutrons be $n$. We know atomic mass number $A=16$ and number of protons $p = 7$. Using the formula $A=p + n$, we can solve for $n$. So $n=A - p=16 - 7=9$.
