Answer:
The atomic mass of this element would be 13 amu.
Explanation:
The subatomic particles provide several bits of information about a given element.
The number of protons is equal to the atomic number of the element. For this element having 7 protons makes the atomic number 7 and makes the element Nitrogen.
The number of protons plus the number of neutrons equals the atomic mass of the element based upon atomic mass units (amus).
For this element 7 protons and 6 neutrons combine to make an atomic mass of 13 amus.
