Is boron radioactive?
There are no radioactive isotopes of boron that are ordinarily found in nature. All elements have synthetic radioactive isotopes, however.
Which of these illustrations shows isotopes of the element boron?
1 and 3
How many protons neutons and electrons are in boron?
Boron has 5 protons and 5 electrons Boron has two stable isotopes, one with 5 neutrons and 6 neutrons.
The average atomic mass of boron is 10.81 amu. Based on the atomic mass of B-10 and the relative abundances of the boron isotopes what is the atomic mass of B-11?
B-10 is 10.013
How many neutrons are in the nucleus of boron?
Boron has 2 isotopes and both are stable thus, depending on the isotope, an atom of Boron could have 5 or 6 neutrons in it nucleus. 10B has 5 neutrons (and 5 protons) 11B has 6 neutrons (and 5 protons) As about about 80% of all boron is 11B, most Boron atoms will be found to have 6 neutrons.
How many isotopes are in boron?
There is 13 isotopes in the element boron. xD
How many isotopes does boron have?
Two stable ones, 10 & 11. Several unstable.

How can isotopes be used in boron?
isotopes are just things of the same element without one or more nuetrons

Is boron a natural or synthetic?
Boron is both: Isotopes with mass numbers of 10 and 11 occur naturally, and isotopes with mass numbers of 8, 9, 12, and 13 have been synthesized.
Is boron a natural or synthetic element?
Boron is both: Isotopes with mass numbers of 10 and 11 occur naturally, and isotopes with mass numbers of 8, 9, 12, and 13 have been synthesized.
How many protons neutons and electrons are in boron?
Boron has 5 protons and 5 electrons Boron has two stable isotopes, one with 5 neutrons and 6 neutrons.
How may protons neutrons and electrons does Boron have?
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
In one atom how many protons and neutrons does the element boron have?
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.
If The average mass of a boron atom is 10.81 what is the chance that you would randomly get one with a mass of 10.81?
Zero. There are NO boron atoms with a mass of 10.81 amu. The value of 10.81 is an average of the masses of the isotopes of boron.There are two stable isotopes of boron: boron-10 and boron-11, with masses of 10.012 amu and 11.009 amu. B-10 has a relative abundance of 19.9% and B-11 has a relative abundance of 80.1%.Do the math:10.012 x 0.199 + 11.009 x 0.801 = 10.81 amu
How can you explain this difference The element boron has an atomic mass of 10.81amu acoording to the periodic tablehowever no single atom of boron has a mass of exactly 10.81amu?
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)+[...]
