What are the characteristics of the oxygen family?
General Characteristics of the Oxygen Group Elements
- Electronic Configuration. The elements of the oxygen family have six electrons in the outermost shell and have the general electronic configuration s ns2 np4.
- Atomic and Ionic Radii.
- Ionisation Enthalpies.
- Electron Gain Enthalpy.
What are the non metals in the oxygen family?
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).
What are 5 characteristics of oxygen?
The key properties of oxygen are listed below:
- It is a colorless, odorless and tasteless gas.
- It readily dissolves in cold water.
- It is highly reactive and form oxides with almost all elements except noble gases.
- Liquid oxygen is strongly paramagnetic.
- It exists in three allotropic forms- monoatomic, diatomic and triatomic.
What is oxygen characteristics?
In normal conditions oxygen is a colourless, odourless and insipid gas; it condensates in a light blue liquid. Oxygen is part of a small group of gasses literally paramagnetic, and it’s the most paramagnetic of all. Liquid oxygen is also slightly paramagnetic.
What does the oxygen group have in common?
Oxygen is in group 16 in the periodic table. All the elements in this group have in common the number of valence electrons in their outer shell (6 valence electrons). The only reason I can see that they may be considered “mixed” is because the group includes non metals and metalloids.
Is the oxygen family reactive?
Oxygen is a member of the chalcogen group on the periodic table and is a highly reactive nonmetallic element. As such, it readily forms compounds (notably, oxides) with almost all other elements.
Why is oxygen non-metal?
Oxygen, carbon, sulfur and chlorine are examples of non-metal elements. Non-metals have properties in common. They are: poor conductors of heat and electricity (they are insulators )
Is the oxygen group a metal or nonmetal?
Group 16 of the periodic table is also called the oxygen group. The first three elements—oxygen (O), sulfur (S), and selenium (Se)—are nonmetals. They are followed by tellurium (Te) (Figure below), a metalloid, and polonium (Po), a metal. All group 16 elements have six valence electrons and are very reactive.
Can oxygen cause a fire?
Oxygen is not flammable, but it can cause other materials that burn to ignite more easily and to burn far more rapidly. The result is that a fire involving oxygen can appear explosive-like.
What are 5 common uses of oxygen?
Common uses of oxygen include production of steel, plastics and textiles, brazing, welding and cutting of steels and other metals, rocket propellant, oxygen therapy, and life support systems in aircraft, submarines, spaceflight and diving.
What are the similarities in the oxygen family?
Each element in this group has six valence electrons and have small atomic radii and large ionic radii. Many of these elements at high concentrations are toxic or damaging. Oxygen and sulfur are chemically similar because sulfur is directly below oxygen in the periodic table.
What are the properties of the oxygen family?
Chalcogens are sometimes collectively referred to as the ‘oxygen family’. Of all the elements in this group, only oxygen is a gas, while the rest are solids, and only oxygen and sulfur are usually found in their pure form. All chalcogens found in metallic ores are found in the form of ions.
Are there any noble gases that are nonmetals?
So, if we include the nonmetals group, halogens, and noble gases, all of the elements that are nonmetals are: Hydrogen (sometimes) Carbon. Nitrogen. Oxygen. Phosphorus. Sulfur. Selenium.
How many elements are in the group of nonmetals?
There are 7 elements that belong to the nonmetals group: Hydrogen (sometimes considered an alkali metal) Carbon. Nitrogen. Oxygen. Phosphorus. Sulfur. Selenium. Although these are the elements in the group nonmetals, there are two additional element groups that could be included, since the halogens and noble gases also are types of nonmetals.
What kind of elements are in the alkali metal family?
The highlighted elements of the periodic table belong to the alkali metal element family. The alkali metals are recognized as a group and family of elements. These elements are metals. Sodium and potassium are examples of elements in this family.
