Sagot :
Answer: Mass number is 15
Explanation:
Mass number of an atom is the sum or total number of protons and neutrons present in the atom. It is represnted by the letter A
The Atomic number (Z) of an atom is defined as the number of protons in an atom and it is equal to the number of electrons present in the atom.
A= n + p
where n is the number of neutrons and p is the number of protons present in the atom
Z = p = e
Where p is the number of protons and e is the number of electrons present in the atom
Z for oxygen atom is 8
So, Z = p = 8 for oxygen atom
If n = 7
then A for oxygen atom with 7 neutrons is given by
A= n + p = 8+7 = 15.
