8 Questions
Explain what covalent bonding is and why it takes a lot of energy to break the bond?
Covalent bonding is the sharing of valence electrons between elements. It takes a lot of energy to break a covalent bond because the shared electrons are held tightly between the elements.
What are semiconductors and how do they fit between conductors and insulators?
Semiconductors are materials that conduct electric current, but not as easily as conductors. They fit between conductors and insulators in terms of their conductivity properties.
What is the basic property of a semiconductor and how does it differ from a normal conductor?
The basic property of a semiconductor is that it 'conducts a little bit.' It carries electric current, but not as easily as a normal conductor.
What is the basic property of a semiconductor?
It conducts a little bit
What materials are examples of semiconductors?
Germanium and silicon
What is the sum of electron current and hole current in semi conducting materials?
$1$
Why do elements share their valence electrons in covalent bonding?
To achieve stability by obtaining a full outer shell of electrons
What type of materials are midway between conductors and insulators?
Semiconductors
Test your knowledge on the properties of covalent bonds and semiconductors. Learn about the sharing of valence electrons and the behavior of semiconducting materials in conducting electric current.
