Card 1
Question: What is an atom?
Answer: An atom is the smallest unit of an element that retains the chemical identity of that element.
Card 2
Question: What are the three primary types of subatomic particles that constitute an atom?
Answer: Protons, neutrons, and electrons.
Card 3
Question: Where are protons located within an atom and what is their charge?
Answer: Protons are located in the central core of the atom, called the nucleus, and carry a positive electrical charge (+1).
Card 4
Question: What is the approximate mass of a proton?
Answer: Approximately 1 atomic mass unit (amu).
Card 5
Question: What characteristic of an atom is determined by the number of protons?
Answer: The element's identity.
Card 6
Question: Where are neutrons located within an atom and what is their charge?
Answer: Neutrons are found in the nucleus alongside protons and are electrically neutral (0).
Card 7
Question: What is the approximate mass of a neutron?
Answer: Approximately 1 amu.
Card 8
Question: What is the primary role of neutrons in an atom?
Answer: To contribute to the atom's mass and to stabilize the nucleus.
Card 9
Question: How do electrons differ from protons and neutrons in terms of mass and location?
Answer: Electrons are much smaller and lighter (approximately 1/1836th of an amu) and occupy a region of space surrounding the nucleus, not confined to it.
Card 10
Question: What is the electrical charge of an electron?
Answer: Negative (-1).
