Classification of Substances
Atoms or molecules of some substances, electrons present in their outermost orbit are weaker than their nuclei, due to which they become free for motion in the permissible range.
These are called electron-free electrons or driver electron conduction electrons. The conductivity of a substance depends on the number of free electrons present in it. Substances can be classified on the basis of conductivity in the following parts
1. Conductors - substances in which free electrons are found in very high numbers and where the flow of electrical current goes smoothly, it is called a driver.
Examples - silver, copper, aluminum, iron and other metals, human body, earth etc.
2 . Electrostatic or insulators - substances in which the number of free electrons is almost negligible and in which the current does not flow, they are called anti-electrons or non-electrons.
Examples - include leather, sulfur, backlight, etc.
3. Dielectrics - All electrons in the atoms of the electro-nucleus are strongly tied because of the strong attraction force of the nucleus. Hence, due to the free electron being found in almost negligible number, there is no flow of electric current. When these substances are placed in the electrical field, the charge becomes induced on their pages.
Therefore, the products of electrophoresis are non-electrochemical substances in which electrifying effects are transmitted without electricity.
Examples - Coach, Wax, Rubber, Paper, Asbestos etc.
Answer:
hiii
your answer is here ;
Explanation:
Matter can be broken down into two categories: pure substances and mixtures. Pure substances are further broken down into elements and compounds. Mixtures are physically combined structures that can be separated into their original components. A chemical substance is composed of one type of atom or molecule.
