3\. Below the symbol is the atomic mass. While this number is a weighted average of the masses of all isotopes of the element, if you round the number to the nearest whole number you will find the mass number of
The differences in matter comes down to the tiniest differences in atomic structure. TL;DR (Too Long; Didn't Read) Understand that isotopes of an element have different mass numbers but the same number of protons. Using the Periodic Table, find the atomic number of the element. The atomic ...
If an element has atomic #32 how many electrons does it have? How many valence electrons (electrons in the outer energy level) does oxygen have? The element of nitrogen has an atomic mass of 15 and atomic number 7. How many neutrons does it have? also write ...

visions of the future: Suddenly, the sky blazes with the radiance of a thousandsuns. Millions of lives burn to ash and shadow. Finally, as nuclearfirestormsincinerate cities and forests, torrents of smoke ascend into the atmosphere to entomb the planet in billowing, black clouds of ash....
Find out more about the podcast here The story is said to have started in Sarov, a place so secretive it can only be entered with prior permission of the Russian authorities. Located about 230 miles (370km) east of Moscow, nestling in flat woodland so dense it is im...
Before going into muon neutrinos, we must learn about muons first. Like electrons, protons, neutrons, muons are elementary particles present in atoms. They have their antimuons as well. Feynman diagram of Muon to electron decay When these muons and antimuons undergo particle decay, an electron ...
The level of excitation depends on the amount of energy that is applied to the atom via heat, light, or electricity. Above is a classic interpretation of what the atom looks like. This simple atom consists of a nucleus (containing the protons and neutrons) and an electron cloud. It's ...
The vastest unexplored territory is located on the neutron-rich side in the upper half of the chart of nuclides and hides the answers to some of the most fundamental questions of nuclear physics like the limits of nuclear stability, element synthesis in the universe or stellar evolution. The ...
