What is the fundamental difference between atoms and ions?
Atoms are neutral particles containing equal numbers of protons and electrons, while ions are charged particles containing an unequal number of protons and electrons.
True or False: Atoms have a net charge.
False
What is an ion?
An ion is an atom or molecule that has a net electric charge due to the loss or gain of one or more electrons.
Which subatomic particle determines the charge of an ion?
Electrons
How do cations differ from anions?
Cations are positively charged ions formed by losing electrons, while anions are negatively charged ions formed by gaining electrons.
Fill in the blank: Atoms are _______ particles.
Neutral
What type of ions have a positive charge?
Cations
What type of ions have a negative charge?
Anions
True or False: Ions have unequal numbers of protons and electrons.
True
What is the charge of an ion that has gained electrons?
Negative
What is the charge of an ion that has lost electrons?
Positive
How do ions differ from atoms in terms of charge?
Ions can have a net charge, while atoms are neutral.
What determines the chemical behavior of an ion?
The number of electrons it has gained or lost.
What is the charge of a neutral atom?
Zero
What is the charge of a cation?
Positive
What is the charge of an anion?
Negative
What happens to an atom when it becomes an ion?
It gains or loses electrons, changing its charge.
What is the charge of an ion with more protons than electrons?
Positive
What is the charge of an ion with more electrons than protons?
Negative
Fill in the blank: Ions have a net ________ charge.
Electric
What is the charge of an ion that has the same number of protons and electrons?
Neutral
What is the main difference between a cation and an anion?
Cations have a positive charge, while anions have a negative charge.
True or False: Atoms can have a net charge.
False
How does an ion differ from a neutral atom?
An ion has a net charge, while a neutral atom does not.
