The Atom Flashcards
What are the tiny subatomic particles called in an Atom?
Electrons, Protons and Neutrons
What is the charge of a Proton?
Positive
Where are Protons located in the atom?
In the nucleus
What is the charge of a Neutron?
Neutral
Where are Neutrons located in the atom?
In the nucleus
How are Protons and Neutrons held together in the nucleus?
A strong nuclear force
Why is a strong nuclear force needed to hold the Protons and Neutrons together?
Because the Protons want to split apart from each other due to their positive charge
What does every atom have?
A positively charged nucleus
What is the charge of an Electron?
Negative
Where are the Electrons found in an atom?
Surrounding the nucleus in shells
Why do the Electrons surround the nucleus?
Because they are attracted to the positively charged nucleas
What do Protons and Neutrons have in common?
They have the same size and therefore the same mass
What is the mass of an Electron?
Nothing
Which 2 particles contribute to the total mass of the atom?
Protons and Neutrons
What can be formed when atoms interact with each other?
Molecules and Compunds
