The element with 5 protons and 7 neutrons would be Boron (atomic number 5). However, the element also having 5 electrons doesn't match the standard atomic structure, so it could be an ionized form of Boron.
Boron-11 is an isotope. The atomic number of Boron is 5 which means it has 5 protons, (if there were more or less protons the element wouldn't be boron). the isotope number (11) is the number of protons plus neutrons. to find out the number of neutrons you would take take the isotope and subtract it by number of protons (11-5) which yields 6. To find the isotope add the number of protons to the number of neutrons.
Five protons makes this the element boron. The number of protons is the atomic number, and determines the identity of an element. This example would be the boron-12 isotope because it contains 5 protons and 7 neutrons.
