What makes a metal more conductive?

Structure of Metals More specifically the metallic structure consists of ‘aligned positive ions’ (cations) in a “sea” of delocalized electrons. This means that the electrons are free to move throughout the structure, and gives rise to properties such as conductivity.

What makes one metal more conductive compared to another?

The conductivity of a metal depends on the electron concentration and mobility of electrons: S [conductivity]=n [electron concentration]*e [electron charge]*M [electron mobility].

Why are some substances more conductive than others?

Compounds with strong conductivity dissociate completely into charged atoms or molecules, or ions, when dissolved in water. These ions can move and carry a current effectively. The higher the concentration of ions, the greater the conductivity.

Why are some materials conductive and others not?

In conductive materials, the outer electrons in each atom can easily come or go, and are called free electrons. In insulating materials, the outer electrons are not so free to move. All metals are electrically conductive.

Why do different metals have different electrical conductivity?

Metals conduct electricity by allowing free electrons to move between the atoms. Atoms of different size or atomic weight will vibrate at a different rate, which changes the pattern of thermal conductivity. If there is less energy transfer between atoms, there is less conductivity.

Why are metals conduct electricity?

Metals conduct electricity by allowing free electrons to move between the atoms. These electrons are not associated with a single atom or covalent bond. Alloys, which are a combination of different metallic elements, tend to offer a lower level of thermal conductivity than pure metals.

Why do metals conduct electricity and non metals do not?

Answer Expert Verified metal conduct electricity because metal loss electron esaily due to this it coduct electricity . Metal conduct electricity because of movement of free electrons . Non metal doesn’t have free electrons so they dont conduct electricity.

Why can some materials conduct while others can t?

The resistance is normally constant for each material, but there is a different resistance for different materials. As the resistance of a material increases, its conductivity goes down, so the amount of current that it conducts must also decrease, according to Ohm’s law: I = V/R.
