Percent composition by element Element: Symbol: Ag Atomic Mass: 107.8682 # of Atoms: 2 Mass Percent: 78.238% Element: Symbol: C Atomic Mass: 12.0107 # of Atoms: 1 Mass Percent: 4.356% Element: Symbol: O Atomic Mass: 15.9994 # of Atoms: 3 Mass Percent: 17.407% Similar chemical formulas Note that all formulas are case-sensitive. Did you mean to find the molecular weight of one of these similar formulas? More information on molar mass and molecular weight In chemistry, the formula weight is a quantity computed by multiplying the atomic weight (in atomic mass units) of each element in a chemical formula by the number of atoms of that element present in the formula, then adding all of these products together. The atomic weights used on this site come from NIST, the National Institute of Standards and Technology. We use the most common isotopes. This is how to calculate molar mass (average molecular weight), which is based on isotropically weighted averages. This is not the same as molecular mass, which is the mass of a single molecule of well-defined isotopes. For bulk stoichiometric calculations, we are usually determining molar mass, which may also be called standard atomic weight or average atomic mass. Formula weights are especially useful in determining the relative weights of reagents and products in a chemical reaction. These relative weights computed from the chemical equation are sometimes called equation weights. If the formula used in calculating molar mass is the mo...

This is a SUPER easy guide on Silver element. In fact, the table mentioned below is the perfect information box (Which gives you every single detail about the Silver element in Periodic table.) So if you want to know anything about Silver element, then this guide is for you. Let’s finish this very quickly. Silver Element (Ag) Information Appearance White metallic luster State (at STP) Solid Position in Periodic table Group: 11, Period: 5, Block: d Category Transition metals Atomic number or Protons 47 Neutrons 61 Electrons 47 Symbol Ag Atomic mass 107.87 u Electrons arrangement or Bohr model 2, 8, 18, 18, 1 Electronic configuration [Kr] 4d 10 5s 1 Atomic radius 172 picometers (van der Waals radius) 1st Ionization energy 7.576 eV Electronegativity 1.93 (Pauling scale) Crystal structure FCC (Face centered cubic) Melting point 1234.9 K or 961.7 °C or 1763.2 °F Boiling point 2435 K or 2162 °C or 3924 °F Density 10.5 g/cm 3 Main isotope 107Ag (51.8%) and 109Ag (48.1%) CAS number 7440-22-4 Let me ask you a question. How many shells does silver have? It’s 5. Right? You have already seen the bohr model of silver atom in the above table. From the Bohr model, it can be found that the number of orbits or shells in silver is 5. Hence, as silver has 5 orbits, it lies in period 5 of the Periodic table. Why is Silver in d-block? Before knowing this reason, first of all I want to ask you a simple question. How can you determine the blocks-wise position of elements? The simple answer: The ...

so atomic mass is the mass of an element that includes the masses of all three subatomic particles. So we're looking at all the protons, neutrons and electrons forgiven element. We can also say that atomic masses of elements can be found by simply looking at the periodic table. So if we take a look here, the first element of the periodic table is H H stands for hydrogen. Now, later on, we'll go into how elements symbols are related to names, but for now realize that is hydrogen, this number below it. This 1.8 here that we have that is its atomic mass. And if we look, we can see that a majority of the elements have atomic masses that are not whole numbers. Well, that's because the atomic mass oven element is an average of all of its isotopes. So hydrogen has several different isotopes, and from those isotopes were taking the average mass. That's why we do not have whole numbers. Now. We can say here that these have this atomic mass can come in different units. Now we're used to one of them, and that would be grams per mole. That's our normal units for atomic mass, but can also be expressed as atomic mass units or Dalton's now recall that an atomic mass units itself is equal to 1.66 times 10 to the negative kg. So just realize when it comes to the periodic table, we have the elements symbol for each of these elements, and this number on the bottom, which is not a whole number, is the atomic mass, the number on the top, which will always be a whole number that is our atomic n...

Radioactivity pops up fairly often in the news. For instance, you might have read about it in discussions of nuclear energy, the Fukushima reactor tragedy, or the development of nuclear weapons. It also shows up in popular culture: many superheroes’ origin stories involve radiation exposure, for instance—or, in the case of Spider-Man, a bite from a radioactive spider. But what exactly does it mean for something to be radioactive? Radioactivity is actually a property of an atom. Radioactive atoms have unstable nuclei, and they will eventually release subatomic particles to become more stable, giving off energy—radiation—in the process. Often, elements come in both radioactive and nonradioactive versions that differ in the number of neutrons they contain. These different versions of elements are called isotopes, and small quantities of radioactive isotopes often occur in nature. For instance, a small amount of carbon exists in the atmosphere as radioactive carbon-14, and the amount of carbon-14 found in fossils allows paleontologists to determine their age. Atoms of each element contain a characteristic number of protons. In fact, the number of protons determines what atom we are looking at (e.g., all atoms with six protons are carbon atoms); the number of protons in an atom is called the atomic number. In contrast, the number of neutrons for a given element can vary. Forms of the same atom that differ only in their number of neutrons are called isotopes. Together, the numbe...

Silver bromide and iodide were important in the history of photography, because of their sensitivity to light. Even with the rise of digital photography, silver salts are still important in producing high-quality images and protecting against illegal copying. Light-sensitive glass (such as photochromic lenses) works on similar principles. It darkens in bright sunlight and becomes transparent in low sunlight. Silver occurs uncombined, and in ores such as argentite and chlorargyrite (horn silver). However, it is mostly extracted from lead-zinc, copper, gold and copper-nickel ores as a by-product of mining for these metals. The metal is recovered either from the ore, or during the electrolytic refining of copper. World production is about 20,000 tonnes per year. Slag heaps near ancient mine workings in Turkey and Greece prove that silver mining started around 3000 BC. The metal was refined by cupellation, a process invented by the Chaldeans, who lived in what is now southern Iraq. It consisted of heating the molten metal in a shallow cup over which blew a strong draft of air. This oxidised the other metals, such as lead and copper, leaving only silver unaffected.
