Does sulfur have 16 neutrons? (b) By referring to a periodic table or a table of elements, we see that sulfur (S) has an atomic number of 16. Thus, each atom or ion of sulfur must contain 16 protons. We are told that the ion also has16neutrons, meaning the mass number of the i...
How many neutrons, protons, and electrons are in carbon? What is the mass in grams of 44.5 mol Xe? Why is Avogadro's number called the mole? Why does one multiply the mass of one element in a given compound by the moles of that compound to find the amount of the elements present in...
example,carbon atomsalways have six protons;hydrogen atomsalways have one; andoxygen atomsalways have eight. Different versions of the same element, called isotopes, can have a different number of neutrons. Elements can also gain or lose electrons to become charged, in which case they are called...
There are many different ways to produce photons, but all of them use the same mechanism inside an atom to do it. This mechanism involves the energizing of electrons orbiting each atom's nucleus. How Nuclear Radiation Works describes protons, neutrons and electrons in some detail. For example,...
Protonshave a positive charge,neutronshave a neutral charge, andelectronshave a negative charge. Note that the atoms themselvescan carrya positive or a negative charge. How? By gaining or losing electrons. Theflow of electronsbetween atoms is what we call electricity. Since our bodies are huge ...
A simplistic model of an atom, known as the Rutherford–Bohr model, Bohr model or Bohr diagram has a central nucleus made up of particles called protons and neutrons. The nucleus is surrounded by orbitals containing electrons. In some materials such as metals, electrons are bound loosely to ...

How many neutrons does element x have if it's atomic number is 42 and it's mass number is 154?Atomic Number and Mass NumberThe atomic number refers to the number of protons in an atom of an element. It also uniquely identifies the element. When you look...
