This element is tellurium with a covalent atomic radius of 140 pm.
Tellurium (Te) and iodine (I) would be in reverse order if the elements were placed in order of atomic mass instead of atomic number.
They show that the periodic table isn't arranged on the basis of increasing atomic mass because iodine has a mass lesser than tellurium. Iodine has a mass of 126.90 and tellurium has a mass of 127.60.
this happens with argon and potassium, and also with cobalt nickel. fun stuff.
I want to know what the atomic mass of tellurium is......... It has not answered my question and I would like to know the answer....
Group-1 has largest atomic radius. It decreases across a period
Tellurium and Iodine
Te (Tellurium)http://www.webelements.com/tellurium/
Chlorine will have the smallest atomic radius, bromine the largest.
Oxygen Family (16) - occur elementally in nature and in combined states - consists of three nonmetals (oxygen, sulfur, and selenium), one metalloid (tellurium), and one metal (polonium) - have six valence electrons - tend to form covalent compounds with other elements - tend to exist as diatomic and polyatomic molecules, such as O2, O3, S6, S8, and Se8 - commonly exist in compounds with the -2 oxidation state, but often exhibit other oxidation states

Iodine's atomic number is 53 whereas tellurium's is 52. Atomic number is basically the number of protons that an element has. Therefore, as iodine has more protons than tellurium, it appears later in the table.

The Atomic Mass usually increases, but there are a few exceptions, such as tellurium to iodine.

The oxygen family is a group of elements located in Group 16 (also known as Group VI A) of the periodic table. The elements in the oxygen family share similar chemical properties and characteristics. The elements in the oxygen family are: Oxygen (O) - Atomic number 8 Sulfur (S) - Atomic number 16 Selenium (Se) - Atomic number 34 Tellurium (Te) - Atomic number 52 Polonium (Po) - Atomic number 84 These elements have six valence electrons in their outermost energy level and often form -2 ions by gaining two electrons to achieve a stable electron configuration.
