Why is the oxygen family grouped together?
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.
Which is the most metallic in the oxygen family and why?
Oxygen has, except for fluorine, the highest electronegativity and electron affinity of any element; the values of these properties then decrease sharply for the remaining members of the group to the extent that tellurium and polonium are regarded as predominantly metallic in nature, tending to lose rather than gain …

What group is oxygen in GCSE?
Group 1 – chemical reactions with oxygen and chlorine
At room temperature, oxygen reacts with the surface of the metal. This forms a white oxide, which covers the surface. The metal below the surface does not react.
Which is the 3rd member of oxygen family?
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. These can be found in nature in both free and combined states.
What are some characteristics of the oxygen family?
Oxygen is a gas at room temperature and 1 atm, and is colorless, odorless, and tasteless. It is the most abundant element by mass in both the Earth’s crust and the human body. It is second to nitrogen as the most abundant element in the atmosphere.
What family is magnesium in?

What family is astatine in?
Group 7A (or VIIA) of the periodic table are the halogens: fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At).
What is the family name of chlorine?
Chlorine is in group 17 of periodic table, also called the halogens, and is not found as the element in nature – only as a compound. The most common of these being salt, or sodium chloride, and the potassium compounds sylvite (or potassium chloride) and carnallite (potassium magnesium chloride hexahydrate).
Are oxygen and selenium in the same period or group?
The chemical properties of each group are related to the number of valence electrons. Compare the number of valence electrons in an atom of oxygen (O) with the number of valence electrons in an atom of selenium (Se). Are oxygen (O) and selenium (Se) in the same period or group? They are in the same group.
How reactive is the oxygen family?
Reactions and Compounds of Oxygen. As in groups 14 and 15, the lightest element in group 16 has the greatest tendency to form multiple bonds. Despite the strength of the O=O. bond (DO2 = 494 kJ/mol), O2 is extremely reactive, reacting directly with nearly all other elements except the noble gases.
What is Group 17 called?
halogen, any of the six nonmetallic elements that constitute Group 17 (Group VIIa) of the periodic table. The halogen elements are fluorine (F), chlorine (Cl), bromine (Br), iodine (I), astatine (At), and tennessine (Ts).
Does the oxygen family gain or lose electrons when bonding?
The oxygen family elements have 6 valence electrons. They gain two electrons and have a -2 charge.
What is the main characteristic of oxygen?
Oxygen O₂ is a gas without color, taste or smell. It dissolves poorly in water, and boils at a temperature of -183 degrees Celsius. Oxygen in liquid form is light blue in color, and in solid form the element forms dark blue crystals. Oxygen melts at a temperature of -218.7 degrees Celsius.
What type of element is oxygen?
oxygen (O), nonmetallic chemical element of Group 16 (VIa, or the oxygen group) of the periodic table.
How many valence electrons does the oxygen family have?
Valence electrons are the electrons in the outermost shell, or energy level, of an atom. For example, oxygen has six valence electrons, two in the 2s subshell and four in the 2p subshell. We can write the configuration of oxygen’s valence electrons as 2s²2p⁴.
How do Group 7 elements react?
When a group 7 element takes part in a reaction, its atoms each gain one electron. These atoms form negatively charged ions . The ions have a stable arrangement of electrons, with a complete outer shell.
What name is given to the group 0?
The elements in group 0 are called the noble gases . They exist as single atoms .
Why oxygen family is called chalcogens?
The group VIA elements are called chalcogens because most ores of copper (Greek chalkos) are oxides or sulfides, and such ores contain traces of selenium and tellurium. Atomic properties of the chalcogens are summarized in the table. This reaction occurs naturally as a result of lightning bolts.
