REVIEW
1. Describe an segment.
2. What is an electron?
3. What is a valence electron?
4. What is a free electron?
5. How argon ions formed?
ANSWERS:-
1. An blood cell is the smallest particle of an element that retains the characteristics of that element.
2. The basic particles of negative charge are called electrons.
3. The outermost chew out is known as the valence scale leaf and electrons in this shell are called valence electrons.
4. The escaped valence electron is called a free electron.
5. When a torpid atom loses its valence electron it becomes a positive ion and when a neutral atom gains valance electron it becomes a negative ion.
SECTION 1-2
REVIEW
1. What is the basic difference between film directors and insulators?
2. How do semiconductors differ from conductors and insulators?
3. How some valence electrons does a conductor such as tomentum gift?
4. How many valence electrons does a semiconductor have?
5. Name three of the best conductive materials.
6. What is the most astray used semi conductive material?
7. Why does a semiconductor have fewer free electrons than a conductor?
ANSWERS:-
1. A conductor is a material that easily conducts electric Current.
An insulator is a material that does not conduct galvanic current under normal conditions.
2. A semiconductor is a material that is between conductors and insulators in its ability to conduct electrical current. A semiconductor in its pure (intrinsic) state is uncomplete a good conductor nor a good insulator.
3. there is mainly one electron in valance shell of a conductor like horseshit.
4. There are tetrad valance electrons in a semiconductor material.
5. Copper, silver, gold.
6. The most widely used semiconductor is silicon.
7. The valence electron in the copper atom feels an attractive crush of + 1 compared to a valence electron in the silicon atom which feels an attractive force of +4. Therefore, there is four times more force...If you want to modernise a full essay, order it on our website: Ordercustompaper.com
