it has 5 protons and 5 neutrons.

∙ 11y ago8 neutrons. It's Atomic Mass is 9 hence the boron-9 or 9B. It must have 5 protons to be a boron atom (if it had 4 it would be berillium and if it had 6 it would be carbon) an atom always has an equal number of protons and electrons ( unless it's an ion, eg Na+ ). Anyway to find the number of neutrons an isotope has simply subtract the number of protons (the atomic number) from its atomic mass, which in this case is 9. This gives you the number of neutrons present in the nucleus then obviously you just double it.

Why does boron-11 have 5 protons and 5 neutrons?
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.
How many particles are found in the nucleus of a uranium atom?
how many particles are found in the nucleus of a uranium atom? 92 protons and x neutrons; the number of the neutrons is dependent of the isotope atomic mass. Also 92 electrons.
What two sub atomic particles are found in the nucleus?
Protons and neutrons; these particles contain quarks and gluons.
Subatomic particles responsible for most of an atom's mass?
Protons and neutrons.
The nucleus of an atom contains what two particles?
nucleus....contains protons & neutrons
The element boron how many protons and neutrons does it have?
Boron has 5 neutrons and 5 protons for its most common isotope
How many neutrons does boron have?
a regular boron atom (5B11 isotope) has six neutrons and five protons
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 neutrons does the atom boron have?
5
How do boron-10 boron-11 differ?
There are 5 neutrons in boron-10 and 6 neutrons in boron-11.
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 many neutrons are found in the nucleus of a boron -11 (B) atom?
5
How many neutrons does Boron 11 have?
It has an atomic number of 5 and hence it has 6 neutrons.
What is the number of neutrons in boron?
There are 6 neutrons.
Is boron protons electrons or neutrons?
Boron is an atom or element, and it contains protons, electrons, and neutrons.
Protons neutrons electrons in boron?
Boron 10: 5 protons, 5 neutrons, 5 electrons Boron 11: 5 protons, 6 neutrons, 5 electrons
How are boron-10 and boron-11 different?
Boron-10 has five protons and 5 neutrons Boron-11 is an atom that contains five protons and six neutrons
