They all have the same number of protons and a different number of neutrons.
Most naturally ocurring elements are a mixture of different isotopes. Look up boron for more details; I didn't look it up, but I can imagine that it consists of a mixture of isotopes that have an atomic mass of 10 and 11; or perhaps some other isotopes too. Different isotopes of an element have the same number of protons, but a different number of neutrons.
There are 5 neutron in b-10, and 6 in boron-11
5 Protons,6 Electrons,5 Neutrons
This is very simple, just look at the periodic table. Boron has the atomic number of 5, meaning that it has five protons and five electrons. As for the neutrons, most chemicals have isotopes, which means that one atom of an element may have a slightly lower or higher neutron count of an atom of the same element. In boron's case, it has two isotopes. Boron-10 would have 5 neutrons, and Boron-11 would have 6 neutrons, although boron-11 makes up somewhere in the range of 80% of known boron atoms.
Boron has a larger atomic radius but a smaller atomic mass.
It's an average number allowing for the relative abundances of different isotopes.
B-10 is 10.013

There are several isotopes of Boron, which have different levels of abundance. I don't know the accurate numbers, but say like 25% of Zu-isotopes are 1 amu, and 75% of Zu-isotopes is 2, it would be 1.75 amu for the Atomic mass. Relating Zu to B of course, what I mean is Boron's different isotopes appear in different abundances and have different masses. 14% of boron may be about 6.882 amu, but just think about it like the above analogy of Zu, where Zu either weighs 1 or 2, but never 1.75. By the way, to find amu for an element: (%1*Iso1)+(%2*Iso2)+[...]
B is the atomic symbol. a number of different Isotopes exist for this element.6B, 7B, 8B, and so on and so forth.
There is 13 isotopes in the element boron. xD
They have different atomic numbers.
Boron-11 (80%) and boron-10 (20%).
There are two isotopes of boron: boron-10 and boron-11 Both have 5 protons and 5 electrons per atomBoron-10 has 5 neutrons and boron-11 has 6 neutronsOverall this gives an atomic weight of 10.8 gmol-1
Two stable ones, 10 & 11. Several unstable.
There are 5 neutron in b-10, and 6 in boron-11
There are no radioactive isotopes of boron that are ordinarily found in nature. All elements have synthetic radioactive isotopes, however.
