Where are electrons located?
In orbitals surrounding the nucleus
What is located in the nucleus?
Protons and neutrons
Number of protons in an atom is equal to
the atomic number
Mass number is

What are isotopes?
Atoms of the same element with different numbers of neutrons
Protons are equal to
electrons
What is a cation?
An ion with a positive charge
What is an anion?
An ion with a negative charge
How does an ion become a cation?
When a neutral atom loses one or more electrons
How does an ion become an anion?
When a neutral atom gains one or more electrons
In the electromagnetic spectrum, in what direction does frequency raise?
From right to left
What are particles in light called?

What is electron affinity?
the amount of energy released when an electron is added to a neutral atom or molecule to form a negative ion
What is ionization energy?
the energy needed to remove an electron from an atom or molecule in the gas phase
