Answer:
C
Explanation:
The presence of mobile electrons explains the reason why there is conduction of electricity in the solid state. Electrons are the part of atoms that are majorly responsible for the different characteristics that substances exhibit.
A good example of the conduction of electricity can be seen in the case of 2 crystalline forms of carbon. While one of the allotropes could conduct electricity, the other allotrope cannot conduct electricity.
The two allotropes we are talking about here is graphite and diamond. While graphite could be used in a whole lot of electrolysis set up as an electrode, diamond does not found use in cases like this despite its crystalline structure. The reason for this is simple.
While diamond does not contain free mobile electron in its molecule, these free mobile electrons are present in a molecule of graphite. These free mobile electrons are the main reason why graphite can conduct electricity and diamond cannot even though they are both crystalline forms of carbon.

Answer:
Z=26, A = 56, charge +3.
Explanation:
The atomic number is represented by Z. Is equal to the total number of protons that the atom has. Z=26.
The atomic mass is represented by A. The number results from the total sum of protons and neutrons of an atom. Both particles have a weight of 1 uma, are in the nucleus and give the mass to the atom.
Mass number (A) = atomic number (Z) + number of neutrons (N)
A = 26 + 30
A = 56
The net charge of the atom can be calculated by subtracting the negative charges from the positive ones. The positive charges come from the protons and the negative ones from the electrons.
26-23=3
This iron ion has a positive charge +3.
