### The Flow of Electron is

• A.

Voltage

• B.

Current

• C.

Wattage

• D.

Resistance

• E.

Electricity

B. Current
Explanation
The flow of electrons is referred to as current. Current is the rate at which electric charge flows through a conductor. It is measured in amperes (A) and is the result of the movement of electrons in a circuit. Voltage, wattage, and resistance are related to current but do not directly represent the flow of electrons. Electricity is a general term that encompasses various aspects of electrical phenomena, including current.

### What is Electrical Pressure

• A.

Resistance

• B.

Wattage

• C.

Voltage

C. Voltage
Explanation
Voltage is the correct answer because it refers to the electrical pressure or force that pushes electric current through a circuit. It is the measure of potential difference between two points in a circuit, determining the flow of electrons. Voltage is measured in volts and is essential for the operation of electrical devices and systems.

### How many Valence Electrons could a conductor have

• A.

1-7

• B.

2-5

• C.

1-3

• D.

4-7

C. 1-3
Explanation
Conductors are materials that have a high number of free electrons that can move easily within the material. Valence electrons are the electrons in the outermost shell of an atom that are involved in bonding. Since conductors have a high number of free electrons, it means that they have a low number of valence electrons. The range of 1-3 valence electrons is the most appropriate answer because it represents materials like metals, which are good conductors due to their low valence electron count.

• 4.

### This is made up from a combination of Atoms

• A.

Matter

• B.

Element

• C.

Nucleus

A. Matter
Explanation
Matter is made up of atoms, which are the basic building blocks of all elements and substances. Atoms combine together to form molecules and compounds, which in turn make up different forms of matter. Therefore, the statement "This is made up from a combination of Atoms" implies that matter is composed of atoms coming together to form various substances and elements.

### What are the most conductive metals... In order

• A.

Copper, Silver, Gold, Aluminum

• B.

Silver, Gold, Copper, Aluminum

• C.

Aluminum, Copper, Silver, Gold

• D.

Silver, Copper, Gold, Aluminum

D. Silver, Copper, Gold, Aluminum
Explanation
The most conductive metals in order are silver, copper, gold, and aluminum. This is because silver has the highest electrical conductivity among all metals, followed by copper. Gold comes next, although it is less conductive than silver and copper. Aluminum has the lowest conductivity among these metals.

### Insulators can contain how many valence electrons

• A.

3-5

• B.

6-8

• C.

2-6

• D.

3-9

B. 6-8
Explanation
Insulators are materials that do not conduct electricity well because they have a completely filled valence shell. Valence electrons are the electrons in the outermost energy level of an atom. The range of 6-8 valence electrons is correct because elements in this range, such as oxygen, sulfur, and chlorine, tend to have a full or almost full valence shell, making them poor conductors of electricity.

Rate this question:

• 7.

### Insulators can conduct current but only if enough pressure is applied

• A.

True

• B.

False

A. True
Explanation
Insulators are materials that do not readily allow the flow of electric current. However, under certain conditions, insulators can conduct current if enough pressure is applied. This is known as the piezoelectric effect, where the mechanical stress applied to an insulating material causes the rearrangement of its internal charges, enabling the flow of current. Therefore, the statement "Insulators can conduct current but only if enough pressure is applied" is true.

### How many coulombs per second equate to one Ampere?

• A.

3

• B.

5

• C.

1

• D.

2

• E.

7

C. 1
Explanation
One Ampere is equivalent to one coulomb per second. This means that in one second, one Ampere of electric current will pass through a point, carrying one coulomb of charge. Therefore, the correct answer is 1.

### Wattage is the measure of the amount of resistance that is being used in a circuit

• A.

True

• B.

False

B. False
Explanation
It is the amount of power that is being used in a circuit

### A device or material that permits current to flow through it easily

• A.

Insulator

• B.

Ground

• C.

Conductor

• D.

Semi-Conductor

C. Conductor
Explanation
A conductor is a device or material that allows electric current to flow through it easily. Unlike insulators, which do not allow the flow of current, conductors have a high conductivity due to the presence of free electrons that can move freely within the material. This property of conductors makes them suitable for transmitting electricity and allows them to be used in various electrical and electronic devices.

### The Atomic number of an element is equal to the number of what in the nucleus of its atom

• A.

Neutrons

• B.

Protons

• C.

Electrons

B. Protons
Explanation
The atomic number of an element is equal to the number of protons in the nucleus of its atom. Protons are positively charged particles found in the nucleus of an atom. Each element has a unique number of protons, which determines its atomic number. Therefore, the correct answer is protons.

### One of the Basic building blocks of nature, and the atom is the smallest part of it

• A.

Nucleus

• B.

Chemical

• C.

Metal

• D.

Element

D. Element
Explanation
An element is a basic building block of nature and the atom is the smallest part of it. Elements are pure substances that cannot be broken down into simpler substances by chemical means. Each element is made up of atoms that have the same number of protons in their nucleus. Therefore, the given answer of "Element" is correct as it aligns with the description provided.
