Question 1 of 10
What is the fundamental building block of matter that contains protons, neutrons, and electrons?
Atoms are the basic units of matter, composed of protons, neutrons, and electrons.
Question 2 of 10
Which subatomic particle carries a negative charge?
Electrons have a negative charge and orbit the nucleus.
Question 3 of 10
What is the charge of a neutron?
Neutrons have no electrical charge.
Question 4 of 10
What is the name given to the electrons in the outermost orbit of an atom that can easily move?
Valence electrons are in the outermost shell and are involved in chemical bonding and electrical conductivity.
Question 5 of 10
What is the flow of electric charges called?
The flow of electric charges is defined as electric current.
Question 6 of 10
In which direction does conventional current flow?
Conventional current flows from the positive terminal to the negative terminal.
Question 7 of 10
Which of the following materials is most likely to have free electrons and be a good conductor of electricity?
Metals have loosely bound electrons which allow for the easy flow of electric charge, making them good conductors.
Question 8 of 10
If an electron leaves an atom, what type of charge does the atom become?
When an electron leaves, the atom has more positive charges (protons) than negative charges (electrons), resulting in a positive charge.
Question 9 of 10
What is the name given to the current flow considering the movement of electrons?
Electron current considers the flow of electrons, which is the actual flow of charge in most circuits.
Question 10 of 10
Which of the following is NOT a source of electricity mentioned in the article?
Coal power was not explicitly mentioned, although other fossil fuel sources such as Petroleum and Natural Gas were.
