Where are Chalcogens on the periodic table?
Group 6A — The Chalcogens. Group 6A (or VIA) of the periodic table are the chalcogens: the nonmetals oxygen (O), sulfur (S), and selenium (Se), the metalloid tellurium (Te), and the metal polonium (Po). The name “chalcogen” means “ore former,” derived from the Greek words chalcos (“ore”) and -gen (“formation”).
What group is iodine in the periodic table?
halogen elements
iodine (I), chemical element, a member of the halogen elements, or Group 17 (Group VIIa) of the periodic table.
Which elements are included in the periodic table?
The elements of the periodic table sorted by atomic number
| Atomic number | Name chemical element | Symbol |

| 1 | Hydrogen | H |
| 2 | Helium | He |
| 3 | Lithium | Li |
| 4 | Beryllium | Be |
Which group elements are known as chalcogens?
oxygen group element, also called chalcogen, any of the six chemical elements making up Group 16 (VIa) of the periodic classification—namely, oxygen (O), sulfur (S), selenium (Se), tellurium (Te), polonium (Po), and livermorium (Lv).
What do you mean by chalcogens?
The chalcogens (ore forming) (/ˈkælkədʒənz/ KAL-kə-jənz) are the chemical elements in group 16 of the periodic table. This group is also known as the oxygen family. It consists of the elements oxygen (O), sulfur (S), selenium (Se), tellurium (Te), and the radioactive element polonium (Po).
What group is argon in?
noble gases
argon (Ar), chemical element, inert gas of Group 18 (noble gases) of the periodic table, terrestrially the most abundant and industrially the most frequently used of the noble gases.
Where did the mineral epsomite get its name?
The natural mineral epsomite was first extracted in 1695, from the mineral waters near Epsom (London), where the mineral name was derived from. Just as kieserite (magnesium sulfate mono hydrate), single crystals rarely occur in nature.
What kind of solubility does epsomite have?
Usually the previously mentioned, distinct, ring-shaped seam of intergrown crystals forms, when the magnesium sulfate containing solute is evaporated. Epsomite shows a low solubility in anhydrous ethanol and glycerin under the microscope.
What do all elements on the periodic table have in common?
All elements within a period share the same highest electron energy level. The columns of the periodic table are called groups. All elements in a group share the same number of valence electrons. The three broad categories of elements are metals, nonmetals, and metalloids. Most elements are metals.
Which is the most rare element on the periodic table?
The most common of these elements are sodium and potassium. Rubidium, lithium, and cesium are more rare, making up, in order, 0.03, 0.007, and 0.0007 percent of the Earth’s crust. These elements are very reactive, and usually occur in nature already combined with other elements.
