If we know the number of protons, then any other information we don't need. The number of protons defines which element an atom is. If the number changes, then the type of element changes along with it. The number of protons is the same as the atomic number, so if you can locate a Periodic Table, you would see that element number 7 is nitrogen. If we wanted to be specific to the isotope, we could also say that it is 14N, with the 14 representing the mass number - the sum of the number of protons and neutrons.
Boron is an atom or element, and it contains protons, electrons, and neutrons.
The gaseous element with 5 valence electrons and fewer neutrons than sodium is Boron. Boron has 5 protons and 5 neutrons, while sodium has 11 protons and about 12 neutrons.
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.
Be- Beryllium
It is the boron element. It contains similar numbers of electrons and protons.
Five protons makes this the element boron. The number of protons is the atomic number, and determines the identity of an element. This example would be the boron-12 isotope because it contains 5 protons and 7 neutrons.
5 protons 8 neutrons try it
The isotope boron-11 has 5 protons and 6 neutrons, but also 5 electrons not 8.
Boron 10: 5 protons, 5 neutrons, 5 electrons Boron 11: 5 protons, 6 neutrons, 5 electrons
The atomic mass of an element is the sum of the number of protons and neutrons in the nucleus. In this case, the element has 4 protons and 5 neutrons, so its atomic mass is 4 + 5 = 9 atomic mass units (amu). The number of electrons does not affect the atomic mass.
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
boron10 would be the isotope that matches these descriptions
