Use the E0 values of the following elements: Zn, Cu, Pb, and Al. Which element is the most active reducing agent?

Chemistry
1 answer:
Alenkinab [10]3 years ago
5 0

Answer:

Al

Explanation:

The reduction potentials of the metals are

Al= -1.66

Zn= -0.76

Cu= +0.34

Pb= -0.13

Hence All has the most negative reduction potential and is the most reducing element among all the elements listed.

Choose the best statement of the octet rule from those listed below atoms lose 8 electrons to become valent atoms lose 8 electro
Mnenie [13.5K]

Answer:

atoms tend to react in order to gain 8 valence electrons

Explanation:

The octet rule describes the tendency of atoms of elements to react in order to have eight electrons in their valence shell. This is because having eight valence electrons confers stability to the atoms of these elements in the compounds they form.

The octet rule only does not apply to the transition elements or the inner transition elements as only the s and p electrons are involved. the electronic configuration in atoms having an octet is s²p⁶.

For example, sodium atom has one valence electron in its valence shell but a complete octet in the inner shell; it will react with chlorine atom which has seven valence electrons to form a stable compound, sodium chloride by donating its one valence electron in order to have an octet. Similarly, the chlorine atom will then have an octet by accepting the one electron from sodium atom.
