STRUCTURE OF ATOM
THE BOHR MODEL
I’m an electron!
I’m a proton!I’m a neutron!
I was walking along and I saw these two.
I was telling jokes to the neutron.The proton and I were having fun.
They looked so happy there together.
I was p o s i t i v e l y charged!I couldn’t have amassed more happiness.
The proton looked happy, so I wandered closer.
I could see the electron coming near.The who? Huh?
They were HUGE next to me!
The electron was so cute!Like a speck of dust, or something…
I didn’t want to seem obvious, so I kept walking.
Around and around the electron goes.Hey electron, you’re making the proton dizzy.
The proton seems so happy with the neutron.
I’m having fun, but I still notice the electron.It won’t bother me if the electron hangs around.
I guess I’ll just wander around out here.
I’m happy hanging out here.The center is cool, but sometimes it can be a “Bohr”.
Electrons circle around the nucleus of an atom.
Protons are a main part of the nucleus of an atom.Neutrons also hang out in the nucleus of an atom.
Electrons have a negative charge. Protons have a positive charge. +Neutrons have no charge. 0
Electrons are little and have a mass of almost zero.
Protons are big and have a mass of one.Neutrons are also big and have a mass of one.
What is the structure of an atom?
• Nucleus – center of the atom– Home of Protons and Neutrons
– Proton• Has a positive (+) charge• Has a relative mass of 1• Determines the atomic number• Found inside the nucleus
What is the structure of an atom?
– Neutron• Has no (0) charge• Has a relative mass of 1• Determines the isotope
– Isotopes are two of the same element with different masses
• Found inside the nucleus
What is the structure of an atom?
• Electron– Has a negative (-) charge– Has a relative mass of 0 (zero)– Determines the ion– Found outside the nucleus
• Bohr model – electrons are in specific energy levels
• Electron cloud model – electrons are in a random cloud
What is the structure of an atom?
Bohr Model
“Planetary Model”
Schrödinger Model
“Electron Cloud Model”
How are P, N, e- related?
• # protons = atomic number
• # electrons = # protons in a neutral atom
• # protons + # neutrons = atomic mass
