What are the groups and families on the periodic table?
The vertical columns on the periodic table are called groups or families because of their similar chemical behavior. All the members of a family of elements have the same number of valence electrons and similar chemical properties. The horizontal rows on the periodic table are called periods. Group (family): A vertical column in the periodic table.

Why is silver named Ag?
Silver's atomic symbol is Ag, which seems to bear little relation to the name of the element. In fact, Ag is short for argentums, the Latin word for silver. The word "silver" is from the Anglo-Saxon word seolfor.

What does 47 mean for silver?
Silver is a transition metal with element symbol Ag and atomic number 47. The element is found in jewelry and currency for its beauty and value and in electronics for its high conductivity and malleability.
What is silver made of?
Natural silver consists of a mixture of two stable isotopes: silver-107 (51.839 percent) and silver-109 (48.161 percent). The metal does not react with moist air or dry oxygen but is oxidized superficially by moist ozone. It is quickly tarnished at room temperature by sulfur or hydrogen sulfide.

Durable and Light The added metals in sterling silver make it an incredibly durable material — it's even stronger than gold. In addition to its light weight, this quality makes it an ideal choice for jewelry that will be worn daily or often.
What is special about silver?
Silver is the best electric conductor of the elements; all other elements are measured against it. It is the only element that scores 100% conductivity, with the next closest element being copper at 97%. Silver is also the best thermal conductor of any metal but has the lowest contact resistance.
Is silver a rare metal?
That being said, silver is currently considered a very rare and undervalued above-ground precious metal. Although it's running at a supply deficit for the time being, many speculate it's only a matter of time before the price of silver reflects its true value.
How much does silver cost?
MONEX Live Silver Spot PricesSilver Spot PricesTodayChangeSilver Prices Per Ounce$19.34-0.50Silver Prices Per Gram$0.62-0.02Silver Prices Per Kilo$621.78-16.07
Why is silver valuable?
As a physical asset, it has intrinsic worth, unlike the dollar or other currencies. Silver holds its value long term and fares well when interest rates are low — and fixed-income investments aren't earning much. In these ways, silver functions like gold as an investment, serving a similar "safe haven" role.
What is Group 12 on the periodic table called?
zinc group element, any of the four chemical elements that constitute Group 12 (IIb) of the periodic table—namely, zinc (Zn), cadmium (Cd), mercury (Hg), and copernicium (Cn).

What is the color of bromine?
Bromine is a chemical element with the symbol Br and atomic number 35. It is the third-lightest halogen, and is a fuming liquid with a deep red color. At room temperature, Bromine evaporates readily to form a red to amber coloured gas. Bromine's properties are intermediate between those of chlorine and iodine.
Who discovered the periodic table?
It was a Russian chemist, Dmitri Mendeleev, who realized that this periodicity occurred and published the first table in 1869. From it, he was able to predict the existence of elements that had not yet been found, and their qualities. He was generally right.

Who predicted the presence of Manganese?
In the nineteenth century, when the periodic table was created, his presence was predicted by the grand old man called Mendeleev who baptized him with the name eka-manganese (which translates to 1-manganese in Sanskrit). However, even after half a century of his “predicted birth”, no one was able to find him naturally.

Who created the periodic table?
The creator of the periodic table, Dmitri Mendeleev, in 1869 began collecting and sorting known properties of elements, like he was playing a game, while traveling by train.
Can periodic table games be used for grade?
The periodic table game available on this page is for entertainment purposes only, and should not be used to grade students on their knowledge of chemical elements.
Does the Modern Periodic Table Change? If So, How and Who Does That?
The periodic table as we know it today is managed by the International Union of Pure and Applied Chemistry, or IUPAC (eye-you-pack).
What is the periodic table?
The periodic table is a tabular display of the chemical elements organized on the basis of their atomic numbers, electron configurations, and chemical properties. The electron configuration is the distribution of electrons of an atom or molecule (or other physical structure) in atomic or molecular orbitals. Knowledge of the electron configuration of different atoms is useful in understanding the structure of the periodic table of elements.
What is the lightest element on the periodic table?
With a standard atomic weight of circa 1.008, hydrogen is the lightest element on the periodic table. Its monatomic form (H) is the most abundant chemical substance in the Universe, constituting roughly 75% of all baryonic mass.
What is the charge of an atom?
Total number of protons in the nucleus is called the atomic number of the atom and is given the symbol Z. The total electrical charge of the nucleus is therefore +Ze, where e (elementary charge) equals to 1,602 x 10-19 coulombs. In a neutral atom there are as many electrons as protons moving about nucleus. It is the electrons that are responsible for the chemical bavavior of atoms, and which identify the various chemical elements.
How to determine the stability of an isotope?
To determine the stability of an isotope you can use the ratio neutron/proton (N/Z). Also to help understand this concept there is a chart of the nuclides, known as a Segre chart. This chart shows a plot of the known nuclides as a function of their atomic and neutron numbers. It can be observed from the chart that there are more neutrons than protons in nuclides with Z greater than about 20 (Calcium). These extra neutrons are necessary for stability of the heavier nuclei. The excess neutrons act somewhat like nuclear glue. Only two stable nuclides have fewer neutrons than protons: hydrogen-1 and helium-3.
How are the chemical properties of a solid, liquid, gas, and plasma determined?
The chemical properties of the atom are determined by the number of protons, in fact, by number and arrangement of electrons. The configuration of these electrons follows from the principles of quantum mechanics. The number of electrons in each element’s electron shells, particularly the outermost valence shell, is the primary factor in determining its chemical bonding behavior. In the periodic table, the elements are listed in order of increasing atomic number Z.
What is the atomic radius of gold?
The atomic radius of Gold atom is 136pm (covalent radius).
What is the mass number of gold?
Mass numbers of typical isotopes of Gold are 197.
