Which particle is responsible for conduction in metals?
This phenomenon is called the Kondo… They are called conduction electrons, since they are responsible for the electrical conductivity of metals. Although the conduction electrons may roam anywhere in the crystal, they are distributed uniformly throughout the entire solid.

Is electron a representative particle?
A representative particle is any particle that can't be broken down into any smaller particles without changing what it is. For example, atoms are representative particles because breaking them down into their components changes the atom. Other representative particles are electrons, ions and formula units.
What is the smallest representative particle of an element?
An atom is the smallest particle of an element, having the same chemical properties as the bulk element. The first accurate theory explaining the nature of matter was Dalton's Atomic Theory: 1. All matter is composed of atoms, and atoms are indivisible and indestructible.

What is the representative particle for sucrose?
moleculeFor sucrose, the representative particle is a molecule, so the number of molecules of sucrose is obtained by multiplying 3.50 moles of sucrose by the conversion factor, Avogadro's number.
How do you find the number of particles in an element?
Calculating the number of particlesThe number of particles in a substance can be calculated using:Number of particles = Avogadro constant × the amount of substance in mol.Calculate the number of water molecules in 0.5 mol of water.Number of water molecules = Avogadro constant x amount of substance in mol.

Three Similarities Between a Compound and an Element
Atoms and Elements
Molecules
- A molecule is a group of two or more atoms that form the smallest identifiable unit into which a pure substance can be divided while retaining the composition and chemical properties of that substance. A molecule is two or more atoms joined by chemical bonds that form the smallest unit of a substance that retains the composition and properties of that substance. Molecules form th…
Formula Unit
- A formula unit in chemistry is the empirical formula of any ionic or covalent network solid compound used as an independent entity for stoichiometric calculations. It is the lowest integer ratio of ions represented in an ionic compound. Examples include ionic NaCl and K2O and covalent networks such as SiO2 and C (such as diamond or graphite). Ionic compounds do not e…
