Boiling points are a measure of intermolecular forces. The intermolecular forces increase with increasing polarization of bonds. Boiling point increases with molecular weight, and with surface area.

If a stable element has an atomic number of 8, how many electrons does it have? HELP PLEASE!!!!!

mash [69]

8 because atomic number is the same as number of protons, protons and electrons have the same amount so that the element is neither positive nor negative.

The hall reaction of an oxidation-reduction reaction shows that iron gains electrons. What does this electron gain mean for iron

AnnZ [28]

Answer: Iron gains electrons mean It is reduced

Explanation:

Oxidation-reduction reaction or redox reaction is defined as the reaction in which oxidation and reduction reactions occur simultaneously.

Oxidation reaction is defined as the reaction in which a substance looses its electrons. The oxidation state of the substance increases.

$Zn\rightarrow Zn^{2+}+2e^-$

Reduction reaction is defined as the reaction in which a substance gains electrons. The oxidation state of the substance gets reduced.

$Fe^{2+}+2e^-\rightarrow Fe$

Thus iron gains electrons mean It is reduced
