Boron, Symbol= B Atomic Weight= 10.811
With 4 protons, 3 electrons, and 5 neutrons, this atom is an isotope of beryllium. The number of protons in an atom determines its identity, so this atom is still beryllium due to its 4 protons. The difference in neutron number makes it an isotope of beryllium.
Neutrons do not affect the neutrality (or charge) of an atom; protons and electrons do. In order to be neutral, the number of protons must be the same as the number of electrons.
10
you can't tell the atomic mass of an atom if either the number of protons or neutrons is missing. But Boron with 5 protons and 6 neutrons has and atomic mass of 11.
A sodium atom has 11 protons.
Boron has 5 protons in an atom. The atomic number is the same number as the amount of protons.
5 protons, 5 electrons and 6 neutrons :)
Boron, Symbol= B Atomic Weight= 10.811
The atomic number of boron (5) indicates the number of protons in the nucleus of a boron atom. This means that a boron atom has 5 protons. Since atoms are electrically neutral, it also tells us that a boron atom has 5 electrons to balance the positive charge of the protons.
5. If it is more or less than 5 protons then it is not boron.
The mass number of an atom is the sum of the number of protons and neutrons in its nucleus. In this case, with 5 protons and 6 neutrons, the mass number of the boron atom would be 5 + 6 = 11.
4 protons and about 5 neutrons
5 protons in one atom of boron. look at the periodic table.
Boron has more protons. It has 5, lithium has 3.
Boron has 5 protons because the atomic number represents the number of protons in an atom.
Protons: 5 Neutrons: 7 Electrons: 5
