Atomic Mass: Atomic mass refers to the weight or mass of an atom of a specific element. It includes the mass of the protons, neutrons, and electrons in the atom. We measure it inAtomic Mass Unit(amu). Element Type: Element type refers to classifying elements into different categories based...
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...
Alpha particles, beta particles, neutrons, gamma rays and cosmic rays are all known as ionizing radiation, meaning that when these rays interact with an atom they can knock off an orbital electron. The loss of an electron can cause problems, including everything from cell death to genetic muta...
These particles, made up of protons and neutrons, are large and can only travel a short distance -- in fact, they can be stopped with just a piece of paper or even your skin. However, inhalation or ingestion of alpha particles can be very dangerous. Once inside your body, alpha ...
nuclear fission to the work of Italian physicist Enrico Fermi. In the 1930s, Fermi demonstrated that elements subjected to neutron bombardment could be transformed into new elements. This work resulted in the discovery of slow neutrons, as well as new elements not represented on theperiodic table...
Use small Styrofoam balls or plastic bouncing balls instead of pom-poms for the nucleus' protons and neutrons. Create a stand from clay and press the bottom edge of the outermost craft ring into it to create a tabletop spinning atom. The clay stand needs to be able to support the weight ...
As we move from left to right across a row on the periodic table of elements, the size of the atoms increases. This is one of the key factors...Become a member and unlock all Study Answers Start today. Try it now Create an account Ask a question...
From the periodic table, O has an atomic number of 8 and an atomic mass of very close to 16.0. A 3D oxygen atom model or picture would therefore show eight protons and eight neutrons in the nucleus and eight electrons somewhere outside the nucleus. The protons and neutrons could be balls...
In hindsight, the name "atom", referring to something fundamentally un-splittable, is rather inaccurate. Not only are atoms formed from smaller particles (protons and neutrons, which in turn are formed from quarks, and electrons), but they can also very much be split. Indeed, "splitting the...
What value is closest to the mass of the atom? How can you find atomic number from mass number? How to find atomic mass on the periodic table How can you find neutrons using mass number? How do you find the mass number of an isotope?
