Most carbon atoms have six neutrons. Although carbon is defined as having six protons, the number of neutrons in a carbon nucleus can vary, which gives rise to the various isotopes of carbon. Fifteen isotopes of carbon, ranging from two to 16 neutrons, have been observed by scientists.
Neutrons are always found within the atom's nucleus. They are one of the three main building blocks on an atom, along with protons and electrons. Each type of element has a specific number of each of these building blocks, which can easily be determined by consulting the periodic table of elements.
Oxygen has 8 neutrons, 8 electrons and 8 protons, making it a neutral element. Neutral elements have the same number of neutrons and protons. Oxygen is the eighth element in the periodic table of elements, with an atomic number of 8.
Hydrogen has no neutrons, just a single proton and a single electron. Most of the mass of an atom lies in its protons and neutrons; hydrogen has a mass of 1 because of the mass of its single proton.
The number of neutrons in an atom of iron is variable, with the most common number being 30. While the number of protons is diagnostic of an atom and does not change without changing the element itself, the number of neutrons varies by isotope.
Silver has 61 neutrons, 47 protons and 47 electrons. The chemical symbol Ag represents silver, stemming from the Latin word "argentum." It has an atomic number of 47.
Nitrogen has seven neutrons. It is element number seven, which means that the atom also has seven electrons and seven protons. Nitrogen has an atomic weight of 14 grams per mole.
Aluminum has 14 neutrons, 13 electrons and 13 protons. Aluminum is a silvery-white metal. Its density is 2.70 grams per cubic centimeter. Its boiling point is 4,566 degrees Fahrenheit, and its melting point is 1,220.58 degrees Fahrenheit.
Copper has 35 neutrons. Because its atomic number is 29, copper also has 29 protons and 29 electrons. Copper is a metal and is a member of group 11 on the periodic table.
The element sodium has 12 neutrons. The element also has an atomic number of 11, meaning that it has 11 electrons and 11 protons. It has an atomic mass of 22.9, which is often rounded up to 23 to accurately determine the number of neutrons in the element.
