Atomic Structure Flashcards
Which sub - atomic particles have the smallest mass
Electrons have the smallest mass
What charge do protons have
Protons are positively charged
What is the mass of a neutron
Neutrons have a mass of 1 AMU
What is the state of a neutron
Neutrons are stable
Where are neutrons located
Neutrons are located in the nucleus
What is the mass of an electron
Electrons have a mass of 1/1850 AMU
What is the mass of a proton
Protons have a mass of 1 AMU
What is the state of an electrons
They are orbit
Where are electrons located
They are located in the shell
What is an element
An element is a chemical substance that is made up of only one kind of atom and cannot be broken down by ordinary chemical means
Which sub - atomic particles has a positive electrical charge?
Protons have a positive electrical charge
What charge do neutrons have
They have a neutral charge
What is an atom
Atoms are the smallest particle of an element that can take part in chemical reaction
What is the state of a proton
Protons are stable
Where are protons located
Protons are located in the nucleus
What is the name of a negative ion
Anion
What is the name of a positive ion
Cation
What is the aim of ion formation
To make the element stable
How are ions formed
They are formed when an atom loses or gains one or more electrons from or to it’s outermost shell
What happens to electrons when cations are formed
They decrease
What happens to electrons when anions are formed
They increase
What is mass number
Mass number = Protons + Neurons
What is atomic number
Atomic Number = Amount of Protons
