When trying to find the number of neutrons, protons or electrons that different chemical species have, the periodic table is your best friend. Take a look at how to use the periodic table as well as nuclear notation to find the number of subatomic particles associated with any chemical species...
Atoms are composed of three particles: protons, neutrons and electrons. The nucleus is composed of protons and neutrons, collectively referred to as nucleons, and have positive and neutral charges, respectively. Electrons are located around the nucleus and have a negative charge. All elemental atom...
Related to this QuestionHow many protons, neutrons, and electrons are in 40K? State its atomic number and mass number. An element has an atomic number of 114 and an atomic mass of 285. How many protons, neutrons, and electrons does a neutral atom of ...
The periodic table, also called the periodic table of elements, is an organized arrangement of the 118 known chemical elements. The chemical elements are arranged from left to right and top to bottom in order of increasing atomic number, or the number of protons in anatom's nucleus, which ge...
Explain the steps to find the inverse of a function. When given a word problem, how do you determine the numerator and denominator of constant of proportionality? How do you show the number of protons and neutrons on a Bohr-Rutherford diagram?
The "27" is the atomic mass number, or the sum of the number of neutrons and protons in the nucleus. If you take an atom of aluminum and put it in a bottle and come back in several million years, it will still be an atom of aluminum. Aluminum-27 is therefore called a stable ...
There are holograms on most driver's licenses, ID cards and credit cards. If you're not old enough to drive or use credit, you can still find holograms around your home. They're part of CD, DVD and software packaging, as well as just about everything sold as "official merchandise...
The pack generally goes out hunting during the day, and the alpha female guards the pups, using distraction to keep predators, usually lions, away from the den. Most of the Leballa pack with the den entrance in the foreground. Credit: Cindy Miller. When we arrived at the scene, we ...
How does an ion enter or exit a cell? Well, that’s whereion channelscome in. As the name implies, these are channels located in the membrane that grant passage to specific kinds of ions. (Note: In most cells, the potassium channels outnumber the sodium ones.) ...
My son, for example, has a glow-in-the-dark yo-yo, a glow-in-the-dark ball, a glow-in-the-dark mobile and even (if you can believe it) a pair of glow-in-the-dark pajamas! They make him easy to find at night! If you have ever seen any of these products, you know that ...
