Questions and Answers List

Question	Answer
Atoms are the smallest building blocks of life.	Atom
Protons neutrons and electrons.	What are the three components of an atom?
Protons contain positive charge while electrons contain negitve charge. *Neutrons are nuetral meaning they have no charge.	Which two components within an atom are positivly and negitivly charged?
The positive charge from the protons is evened out by the negitive charge from the electrons. (There's an even number of protons and electrons.)	Why is it that an atom may not be (positivly/negitivly) charged?
An ion is when an atom either gains or loses a number of electrons.	What is an ion?
The act of an atom losing a number of electrons and becoming positivly charged.	Caiton
The act of an atom gaining a number of electrons and becoming negitivly charged.	Anion
The number of a protons within an atom.	Atomic number
The amount of electrons plus neutrons within an atom.	Mass number
You subtract the Atomic number (Protons) from the Mass number (Protons+Neutrons). *Since the Mass number is the number of protons plus neutrons subtracting the Atomic Number which is the number of protons from the Mass number will leave you with the neutrons. Mass number - Atomic number = Amount of Neutrons	How do you calculate the amount of neutrons within an atom?
