1. Atomic Structure Flashcards
How many typesa of particles is an atom made up of?
3
What are the names of the particles that make up an atom?
Proton, Electron, neutron
What is the charge and mass of a Proton
Charge: + 1.6e-19
Mass: 1.67e-27
What is the charge and mass of a neutron
Charge: 0
Mass: 1.67e-27
What is the charge and mass of an electron
Charge: -1.6e-19
Mass: 9.11e-31
What is a proton number?
A proton number is the number of protons in the nucleus, and as long as it is a neutral atom, it will also be equal to the number of electrons.
What is the nucleon number?
The nucleon number tells you the number of particles within the Nucleus, so it will tell you the number of protons and neutrons within an atom
What is Specific Charge?
Specific Charge is the ratio of a particles charge to it’s mass, to calculate it you divide an atoms charge in coulombs by its mass in kilograms.
What is an Isotope?
An Isotope is an atom with the same number of protons but different number of neutrons.
Does changing the number of neutrons affect an atom’s chemical properties?
No, but changing the number of neutrons will affect the atom’s stability.
How does the ratio of neutrons when compared to protons affect stability?
The greater the number of neutrons when compared to the number of protons leads to a much lower stability.
