The Atom Flashcards
An Atom contains…
Protons
Neutrons
Electrons
Where is the proton and the neutron of an atom located
In the Nucleus
Why does the Nucleus of an atom have a positive charge?
Because the Protons have a positive charge and the Neutrons have no charge, therefore making the overall charge Positive
Relative Charge of a Proton
+1
Relative charge of a neutron
0
Relative charge of an electron
-1
Where are the electrons in an Atoms located
Around the Nucleus in different orbits
The shells around an Atom are called…
Electron shells
Which two particles in an atom are the same amount
Protons=Electrons
Why do atoms have no overall charge?
Because they have the same number of Protons as Electrons, and they both cancel each other out
What do you call an atom where the number of Protons and electrons are unequal
An ion
What does the Atomic number of an element tell you?
the amount of protons
What does the mass number of an element tell you
the amount of protons and neutrons
