These can be found in nature in both free and combined states. The oxygen passes into the atmosphere and the hydrogen joins with carbon dioxide to produce biomass. These are named as oxygen family after the name of the first member of the group. Overall, the carbon family elements are stable and tend to be fairly unreactive. The electronic configuration is n s 2 n p 4 . Except for lead, all of the carbon family elements exist as different forms or allotropes. The elements tend to form covalent compounds, though tin and lead also form ionic compounds. Oxygen: The chemical configuration of oxygen is 1s 2 2s 2 2p 4. The oxygen family consists of the elements that make up group 16 on the periodic table: oxygen, sulfur, selenium, tellurium, and polonium. Physical and Chemical Properties of Chalcogens. Oxygen is known to react with other atoms, and works to form rust through oxidization. The most common substances, such as oxygen, are states, matter, solids, liquids, gases, and plasma. It is also the least dense at 0.00143 g/cm 3. Photosynthesis uses energy from the sun to split water into oxygen and hydrogen. they exist naturally in various mineral salts in […] (b) This is because halogens are reactive non-metals. The smallest chalcogen is oxygen, which has small atoms having 2 and 6 electrons in its shells. The carbon family elements have widely variable physical and chemical properties. Physical state and molecular structure of oxygen family - definition The elements of oxygen family have six electrons in the valence shell. The elemental structure is a cubic crystal shape. Physical Properties Oxygen exists in all three forms - liquid, solid, and gas. (a) Halogen is a Greek word which means salt-former’. These elements all have six electrons in their outermost energy level, accounting for some common chemical properties among them. The chalcogens (/ ˈ k æ l k ə dʒ ɪ n z /) 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). See the article on Oxygen Element for additional information and facts about this substance. Germanium found in traces in … However, oxygen gas is colourless, odourless, and tasteless. The elements oxygen (O), sulphur (S), selenium (Se), tellurium (Te) and polonium (Po) constitute group 16 elements of the periodic table. Physical and Chemical Properties of Group 17 Elements Group 17 Elements: The Halogens The elements in Group 17 are: Fluorine Chlorine Bromine Iodine Astatine These elements are known as halogens. Physical properties of Carbon Family (1) Non-metallic nature : The non-metallic nature decreases along the group. The chalcogen with the lowest atomic radius and ionic radius is oxygen, whereas the chalcogen with the largest atomic/ionic radius (excluding livermorium) is polonium. Physical Properties of the Chalcogens Atomic/Ionic Radii of the Chalcogens. The chemical and physical properties of oxygen make it different from other elements. The chemically uncharacterized synthetic element livermorium (Lv) is predicted to be a chalcogen as well. Group 16: General Properties and Reactions The oxygen family, also called the chalcogens, consists of the elements found in Group 16 of the periodic table and is considered among the main group elements. It consists of the elements oxygen, sulfur, selenium, tellurium and polonium. C Si Ge Sn Pb ... CO 2 petroleum and natural gas Silicon is the second most abundant element after oxygen in earth’s crust in form of silicates and silica. The first four elements of this group are collectively known as chalcogens (meaning ore forming elements) because […] The liquid and solid forms are a pale blue colour. The atomic radii or the ionic radii of elements increases while progressing down a group.
