Answer:
Boron-11
Step-by-step explanation:
In the Bohr model of the picture, it can be seen that the number of electrons and protons is equal to 5, and the number of neutrons is equal to 6.
The atomic mass is computed as follows:
atomic mass = number of protons + number of neutrons
atomic mass = 5 + 6 = 11
The number of protons defines the name of the element, in this case, is Boron.
The atomic mass defines the name of the isotope, in this case, Boron-11
