Question

Which element is 5 protons, 6 neutrons, and 5 electrons?

Answer 1

The element with 5 protons is boron (B). Since it has 5 electrons, it is neutral in charge. The presence of 6 neutrons indicates that this is the isotope of boron known as boron-11 (B-11), which has a mass number of 11 (5 protons + 6 neutrons).
