If you know only the number of neutrons can you determine what the element is?
It is not possible to accurately identify an element given only the number of neutrons. All atoms are made of three particles: electrons, protons and neutrons. The number of electrons is equal to the number of protons if the atom is uncharged. The atomic mass of an element is the sum of the mass of all the particles. As electrons have a very small mass as compared to the other constituent particles, the mass of an atom can be taken to be the sum of the mass of protons and neutrons. The atomic number of an atom is the number of neutrons it has. This is unique and most chemical properties of an element are determined by its atomic number.
The number of neutrons in the atoms of many elements is the same. For example, boron and carbon have 6 neutrons each, fluorine and neon have 10 neutrons each, etc.
Different isotopes of an elements have the same number of protons but differ in the number of neutrons in the atom. This makes it virtually impossible to uniquely identify an element if only the number of neutrons in the atom is given.
No, you cant determine an element if you only know the number of neutrons. This is because you need to know the number of protons and or electrons in order to be able to identify an element, because these numbers are what are used to get the atomic number of an atom.
No. The number of protons is what defines an element and is the only subatomic particle that is constant for each element. Number of neutrons can change creating isotopes of the element while the electrons can either be added or removed making ions.
The number of neutrons can be determined by knowing the mass number and the atomic number (equals the number of protons) and finding the difference between them...Example The isotope C-14 has a mass number of 14 and an atomic number of 6: 14-6 = 8 neutrons.
