What is Group 17 on the periodic table 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).

What do the elements in the oxygen family group 16 have in common?

The oxygen family consists of the elements that make up group 16 on the periodic table: oxygen, sulfur, selenium, tellurium, and polonium. These elements all have six electrons in their outermost energy level, accounting for some common chemical properties among them.

What family is oxygen in?

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 makes the oxygen family a family?

Oxygen Family Each has six of the desired eight electrons required for the octet in its highest energy level. This means that it takes or accepts two electrons from atoms of other elements to form anions or shares two electrons to form covalent bonds. Oxygen and sulfur are common elements.

What element is in group 16 period 5?

Tellurium
Group 16 elements are chalcogens in which the element placed in the fifth period is -Tellurium. It is represented by the chemical symbol Te. Tellurium has atomic number 52 which contain 52 protons and electrons in a neutral state.

What is meant by 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.

Who are the members of the oxygen family?

The elements Oxygen (O), Sulfur (S), Selenium (Se), Tellurium (Te) and Polonium (Po) together constitute group 16 of the long form of Periodic table and are collectively referred to as Members of “Oxygen Family”. These elements are also known as Chalcogens (meaning “Ore forming”) because most of these elements exist in the form of ores.

What is the atomic number of oxygen on the periodic table?

Oxygen – Periodic Table Element Oxygen Atomic Number 8 Symbol O Element Category Non Metal Phase at STP Gas

How many protons and electrons does oxygen have?

Oxygen is a 8. chemical element in the periodic table of elements. It has 8 protons and 8 electrons in the atomic structure. The chemical symbol for Oxygen is O.

What are the physical properties of Group 16 oxygen?

(ii) Physical State- Oxygen is a colourless diatomic gas while other members are solids. (iii) Density- The densities of elements of group 16 increases gradually on moving down the group from ‘O’ to ‘Po’ due to increase in atomic mass which dominates the effect of increase in atomic size.
