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.
Before continuing with an answer it should be clarified that the question flawed. Elements are identified by the number of protons in the nucleus. Boron has 5 protons, NOT 6. An atom with 6 protons would be an isotope of CARBON. An atom with 6 protons and 6 neutrons would be Carbon-12.
Boron-11 is an isotope of boron. Isotopes are atoms of the same element differing only in the number of neutrons. All atoms are thus "isotopes", but most of the time when people speak of an isotope, they are referring to one that differs from the most common isotope. For boron, the most common isotope is 11B (Boron-11), which makes up about 80% of naturally occurring boron. The remaining 20% is 10B (Boron-10), thus the average atomic weight of Boron is listed as about 10.8 g/mole. Boron-11 has 5 protons and 6 neutrons. Boron-10 has 5 protons and 5 neutrons.
"Lol, didn't I said that in the first answer........ ~.~"
This isn't true. Boron-11 has 5 protons and 6 neutrons.
An atom with 6 protons and 6 neutrons would be carbon-12.
The 11, in boron-11 is the Atomic Mass of the atom, which is equal to the sum of the number of protons and neutrons in the nucleus. All boron atoms have 5 protons, this is what makes it boron. Therefor, in order to have a mass of 11, a boron atom must also have 6 protons (5+6=11).
The atomic number for Boron is 5, which means it always will have 5 protons. B-11 has a mass number 11 so 11-5= 6 neutrons. Most elements have different isotopes which means they have varying numbers of neutrons. If the number of protons changes however, then it is a completely different element.
Ex. Boron-11 5 protons 6 neutrons
Boron-12 5 protons 7 neutrons
Carbon-12 6 protons 6 neutrons
Carbon-13 6 protons 7 neutrons
Boron-11 is an isotope. It still contains 5 protons and 5 neutrons, but has acquired an extra neutron.
No, Boron 11 has 5 protons and 6 neutrons.
Name the elements that has 5 protons
Protons and neutrons; these particles contain quarks and gluons.
it has 5 protons and 5 neutrons.
Protons and neutrons.
nucleus....contains protons & neutrons
Protons + Electrons - Neutrons 0
Boron 10: 5 protons, 5 neutrons, 5 electrons Boron 11: 5 protons, 6 neutrons, 5 electrons
5 electrons. 5 protons. 5/6 neutrons.
4 protons and about 5 neutrons
Boron has 5 neutrons and 5 protons for its most common isotope
Boron (symbol B, atom number 5) is build up with:5 protons, 5 electrons and 5 or 6 neutrons, depending on the mass number of the two possible isotopes: B-(10) has 5 neutrons and B-(11) has 6 of them respectively.
Beryllium has 4 protons, 5 neutrons and 4 electrons.
Boron has 5 neutrons and 5 protons for its most common isotope
Boron-11 has 5 protons and 6 neutrons. This is because each element has a specific number of protons in its atoms that never changes. Boron atoms always have 5 protons. And when the number of protons (5) is subtracted from the mass number (11), the result is the number of neutrons (6).
4 protons, 4 electrons and 5 neutrons
2 protons 3 neutrons
Boron has 5 electrons and protons; the number of neutrons is specific for each isotope. Number of neutrons in a boron isotope = Mass number - 5
There would be 6 protons and 5 neutrons. Such isotope does not exist though.
