Of the elements fe, hg, u, te, and y which is considered a group a element? a. fe b. hg c. te d. y

The correct option is C.

Explanation: Periodic table is divided into periods and groups.

The elements are divided into Group A and Group B.

Transition elements are put into Group B and rest other elements are put into Group A .

In the given elements, 3 of them are transition elements and one of it is a P-block element.

Fe, Hg and Y are the transition elements and belong to Groups VIII-B, II-B and III-B groups respectively.

Te (Tellurium) is a P-block element and belongs to VI-A group.

Hence, the correct option is C.

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.
