In comparison of metals to nonmetals, metals tend to have (choose 3)
A. higher electronegativity values
B. lower ionization energy values
C. negative charges
D. greater conductivity
E. higher ionization energy values
F. lower electronegativity values
G. lower conductivity

B.

D.

F.

Explanation:

Metals tend to me elements of groups I and II

These atoms have low ionization energy, meaning they can easily lose electrons because of their lower mass number – compared to elements in the same period – meaning their valence electrons are loosely held by the nucleus.  This also means that they have low electronegativity – the tendency of the atoms to attract electrons clouds to itself such as in a bond. These metals atoms also form metallic bonds with themselves (unlike nonmetals have preferred covalent bonds) hence they have delocalized electrons that make them good conductors of electricity and heat.

answer: - 3.) the oxidation state of nitrogen in no changes from +2 to 0, and the oxidation state of carbon in co changes from +2 to +4 as the reaction proceeds.

solution: - as per the rules, oxidation number of oxygen in its compounds is -2. the sum of oxidation numbers of all the elements of a molecule or compound is zero.

also, the oxidation number in elemental form is zero.

in no, the oxidation number of o is -2 so the oxidation number of n is +2 so that the sum is zero.

similarly, the oxidation number of c in co is +2 and o is -2.

on product side the oxidation number of n is 0 as it is in the elemental form() .

oxidation number of c in carbon dioxide is +4 as there are two oxygen in it and we know that each oxygen is -2.

so, oxidation number of n is changing from +2 to 0 and the oxidation number of c is changing from +2 to +4.

since nitrogen is reduced and hence no is acting as an oxidizing agent. carbon is oxidized and so co is acting as a reducing agent.

so, the right choice is number 3.)the oxidation state of nitrogen in no changes from +2 to 0, and the oxidation state of carbon in co changes from +2 to +4 as the reaction proceeds.

the answer is minerals.
