Answer:

Semiconductors are poor conductors at low temperatures, but their resistance decreases with increasing temperature.

Explanation:

A semiconductor can be defined as a crystalline solid substance that has its conductivity lying between that of a metal and an insulator, due to the effects of temperature or an addition of an impurity. Semiconductors are classified into two main categories;

1. Extrinsic semiconductor.

2. Intrinsic semiconductor.

The statement which best describes the electrical conductivity of metals and semiconductors is that semiconductors are poor conductors at low temperatures, but their resistance decreases with increasing temperature.

This ultimately implies that, semiconductors are typically an insulator (poor conductor) at low temperatures and a good conductor at high temperatures.

Additionally, conduction involves the transfer of electric charge or thermal energy due to the movement of particles. When the conduction relates to electric charge, it is known as electrical conduction while when it relates to thermal energy, it is known as heat conduction.

The element lithium (Li) has 3 protons and 3 electrons. The element fluorine (F) has 9 protons and 9 electrons. An atom of the e
Naddik [55]

When an atom of the element lithium (Li) transfers an electron to an atom of the element fluorine (F), then the bond results between the atoms is ionic bond.

<h3>what is chemical bond? </h3>

A chemical bond is defined as the bond which holds atoms together in molecules.

Bonds arise due to the electrostatic forces present between positively charged atomic nuclei and negatively charged electrons.

<h3>Types of chemical bond</h3>
  1. Ionic bond
  2. Covalent bond
  3. Coordinate bond

<h3>What is Ionic bond ? </h3>

Ionic bond is defined as the transfer of electron from one atom to another atom.

Since, electron transfer from lithium to fluroine. Thus lithium get positive charge and fluorine occupy negative charge.

Thus, the bond form between lithium atom and fluorine atom is ionic bond.
