The energy gap in band theory is almost equivalent to zero in conductors. It is roughly equivalent to I e V in semiconductors and about 5 e V in insulators.
In solid-state physics, the band theory is a theoretical model that describes the states of electrons in solid materials that can only have energy values that fall inside particular narrow ranges. The behavior of every other particle nearby affects how an electron behaves in a material and, consequently, how much energy it has.
The quantum state that an electron assumes inside a solid metal is described by the band theory of solids. There are numerous distinct energy levels present in every molecule. Band theory does a good job of explaining how electrons behave inside molecules. Science's quantum revolution provided part of the knowledge that went into the development of band theory.

Answer:
3S₈ + 28Br₂ => 8S₃Br₇
Explanation:
Start with either sulfur (S) or bromine (Br) and balance ...
3S₈ + Br₂ => 8S₃Br₇ or S₈ + 7/2Br₂ => S₃Br₇
Balance the remaining reactant ...
3S₈ + 56/2Br₂ => 8S₃Br₇
Remove fractions by multiplying by the fraction's denominator
2(3S₈ + 56/2Br₂ => 8S₃Br₇) => 6S₈ + 56Br₂ => 16S₃Br₇
Reduce to smallest whole number ratio => standard equation at STP ...
3S₈ + 28Br₂ => 8S₃Br₇
Answer:
It is not a gas because its particles do not have large spaces between them.
Explanation:
Solids and liquids have a lot of particles with few spaces between them. Also, gas particles move rapidly in each direction.
Aluminum Al2713 has an atomic molar mass of 27 grams per mole.
Al has 13 protons (hence number 13) and it most common isotope 14 neutrons for a total mass of 27 amu. ( The 13 electrons add no measurable mass to the atom)
Take the grams and divide by the molar mass
= 2 moles
