How many neutrons does sodium have? What is sodium bicarbonate made of? What is the chemical element symbol of sodium? How is a crystal lattice formed? How do sodium and chlorine both achieve stable electron configurations when they react?
How many neutrons does it have? If carbon has an atomic number of 6, and a mass number of 14, how many neutrons are in the atom? If the atomic number of an element is 12 and the atomic mass is 25: a. How many protons are there in the nucleus? b...
How does an atom try to fill its valence shell? If you know the atomic number and the mass number of an isotope of an element, how can you determine the number of protons and neutrons? Explain the concept of the mole. How many electrons does aluminium have? Calculate the number of mole...
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...
Does light travel as a wave, a ray or a stream of particles? Is it a single color or many colors mixed together? Does it have a frequency like sound? And what are some of the common properties of light, such as absorption, reflection, refraction and diffraction? You might think ...
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,...
OK, so when a cell is in the RMP stage, sodium and potassium ions are both present on either side of the membrane. Cool beans. But — how do they cross the barrier? How does an ion enter or exit a cell? Well, that’s whereion channelscome in. As the name implies, these are ch...
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...
atomHow Nuclear Radiation Worksdescribes protons, neutrons and electrons in some detail. For example, hydrogen atoms have one electron orbiting the nucleus. Helium atoms have two electrons orbiting the nucleus. Aluminum atoms have 13 electrons circling the nucleus. Each atom has a preferred number of...
This simple atom consists of a nucleus (containing the protons and neutrons) and an electron cloud. It's helpful to think of the electrons in this cloud circling the nucleus in many different orbits. Absorbing Energy Absorption of energy: An atom absorbs energy in the form of heat, light ...
