(a) The atomic number is the same as the mass number (b) The atomic number is the same as the number of protons (c) The identity of a chemical element is determined by the number of valence electrons (d) The radi How do you determine the atomic orbitals of an atom or molecule? Wh...
These atomic numbers correspond to the number of protons and electrons, as well as the approximate average number of neutrons, in each element. You can get an estimate of neutron number for an element by subtracting its atomic number from its atomic mass, listed at the center bottom of ...
he used an example where we were given abundance and amu for all the isotopes and just had to use the average atomic mass formula And this is exactly what you need to do here. You are just not given one piece of information, so you have to determine it for yourself. Logged What men...
How do we use a cost driver for overhead costs to calculate the manufacturing overhead cost per unit for a product? What are the examples of a unit rate? How do you work out variable and fixed costs? What is the difference between cost pools and cost drivers? Give examples. ...
What is atomic energy?It's not immediately obvious but tall buildings store energy—potential energy. You have to work hard to lift bricks and other building materials up off the ground into the right position and, as long as they remain where you put them, they can store that energy ...
Radioactivity: Discovering the Nucleus, the Proton and the Neutron - "Atoms are in your body, the chair you are sitting in, your desk and even in the air. Learn about the particles that make the universe possible."

Every subject has its own language. For instance, mathematicians talk about derivatives, integrals and axioms; and chemists discuss atomic mass, mole and stoichiometry. Similarly, economics also has its own language: supply, demand, and comparative advantage are some examples. You will learn new ter...
That's similar to what's happening on an atomic level with an ion exchange. So how does it work? To replace sodium with potassium, you first must break the ionic bond sodium has with the glass. That's why the potassium salt bath is so hot -- Corning says the bath reaches a ...
