Most elements are . The elements on the left side of the stairstep line on the of Elements are metals. Some physical properties of metals
are (shininess), good conductors of and
, and can be hammered into sheets. Non-metals are found
to the of the stair-step line on the Periodic Table of Elements. The characters of nonmetals are
to those of metals. Nonmetals have a dull or
. Nonmetals also break easily and are not
or . Metalloids that are on
sides of the zig-zag line have both properties of metals and nonmetals. Metalloids can be
or dull and can conduct heat and electricity well.

The elements with the tendency to lose electrons are termed metals. The elements with the tendency to gain electrons are nonmetals. And, the elements with properties between metals and nonmetals are metalloids.

Explanation:

Most of the elements in the periodic table are metals. Most of them are present on the left side of the periodic table. Elements to the far right of the periodic table are nonmetals. Elements which exhibit properties of both metals and nonmetals and are termed metalloids or semimetals.

Metals are defined as the elements which loose electrons to attain stable electronic configuration. They are hard ,malleable ( betaen to sheets) ,ductile ( drawn into wires) ,sonorous ( produce sound ) etc.

Non-metals are defined as the elements which gain electrons to attain stable electronic configuration. They are brittle and soft and are the poor conductors of heat and electricity.

Metalloids are defined as the elements which show properties of both metals and non-metals. Metalloids are typically semi-conductors, which means that they both insulate and conduct electricity.

when [oh-] is 10-5  m, and [h3o+] is 10-9  m, the poh is 5 and ph is 9. again in both cases the sum of ph and poh is 14. however, the hydrogen ion concentration is not always going to be equal to exactly 1 x 10 raised to a negative number. for example, we skipped over the value of 2.0 x 10-7.

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.
