Atomic Structure Flashcards
What is the definition of a proton?
A subatomic particle with positive charge found inside the nucleus of an atom
What is the charge of a proton?
+1
What is the mass number of a proton?
1
What is the definition of an electron?
A subatomic particle with negative charge found outside the nucleus in orbital shells
What is the mass number of an electron?
1/2000
What is the charge of an electron?
-1
What is the definition of a neutron
A subatomic particle with no charge found inside the nucleus of an atom
What is the charge of a neutron?
0
What is the mass of a neutron?
1
What is the definition of mass number?
The total number of protons and neutrons in an atom of that element.
What is the definition of atomic number?
The number of protons in the nucleus
Describe the Bohr model
Nucleus containing protons and neutrons
Series concentric circles that extend beyond the nucleus
Concentric circles = orbital shells where e- reside
What is binding energy
The energy required to separate the nucleus into its constituents.
It exists because of electrostatic attraction between the protons in nucleus and orbital electrons
What is the relationship between binding energy and energy levels?
The closer the orbital shell is located to the nucleus the higher the binding energy of the orbital e-
Whats the relationship between potential energy and the nucleus?
The closer you are to the nucleus the less potential energy there is
