Atoms Flashcards
Neutrons and protons make
Create an atom
Unstable model
A model that doesnβt have the right amount of protons and neutrons
Neutral atom
When the amount of protons and electrons are the same.
Negative atom
When thereβs more electrons then protons in a atom
Bohr model
The simplest model of an atom. Includes nucleus, energy level, protons, electrons, and neutrons.
Area around the nucleus where electrons are located
Energy level/ electron cloud
Determines where the electrons are located.
The amount of energy a electron has
More energy means
Electrons are father form the nucleus
Less energy means
Electrons are closer to the nucleus
Electrons located in the outermost ring
Valence Electrons
Where the majority of the mass is
nucleus
Where the majority of volume is in
Electron cloud
Atomic number
The amount of protons in a atom
Mass number
The amount of protons and neutrons
Energy levels hold what amount of electrons
1 energy level holds 2 electrons, 2 energy levels hold 8 electrons, 3 energy levels hold 18 electrons.
