Why does boron have 6 neutrons?

Why does boron have 6 neutrons? We are given that boron-10 had five protons in its nucleus, and any element always has the same number of protons in its nucleus (atomic number). For boron-11 this total is 11, and five of the particles are protons, thus 11−5=6 neutrons.
