The Atom Flashcards
What is an Atom
smallest unit of an element that maintains the properties of that element.
What does the greek word Atom mean
It means can no longer be cut or divided
What are Atoms made up of?
Atoms are made up of electrons,neutrons, protons and nucleus.
Where can you find Protons and Neutrons
In the Nucleus
Where can you find a Electron
Electrons are found outside the Nucleus
Is a Electron negatively charged or positively charged
Negatively charged
What can Protons, Neutrons and Electrons be classified by
They can be classified by mass, charge and location in an atom.
What are Isotopes
They are atoms that have the same number of protons but have a different number of neutrons.
What are the two tipes of electron clouds
P-clouds and S-clouds
Are Protons and Neutrons outside or inside the Nucleus
Both inside
What charge does a Neutron have
Neutral
What charge does a Proton have
Positive
What happens when a Proton and an Electron are not equal
They turn into an negative ion
What happens when there are more Electrons than Protons
It becomes a positive ion
What two parts of an Atom are opposite but equal so they cancel out?
Proton and Electron
Is it true or false that two elements can have the same set of energy levels
false
What is an orbital
An orbital is out side the nucleus and is where electrons live.
What is a electron configuration
It is how electrons are arranged in the orbitals of an atom
What is the electrons most stable configuration
When the electrons are in orbitals with the least amunt of energy.
What needs to happen in order for a ground state to occur
The orbitals have to be at the lowest possible energy level
