AQA AS Physics 1. Atomic Structure
Cards in this deck (7)
- 1What is the atomic number? (What it is more commonly known as and what symbol represents it?)Number of protons in the nucleus
It is also known as the proton number and has a symbol of Z. - 2What is the nucleon number? (What it is more commonly known as and what symbol represents it?)Number of neutrons and protons in the nucleus
It is also known as the mass number and has a symbol of A - 3What is a fundamental particle?A fundamental particle is a particles that cannot be split up into anything smaller.
- 4Describe specific charge? (What is the equation and units for specific charge?)Specific charge of particle is the ratio of its charge to its mass.
Specific Charge = charge / mass
Units: C kg -1 - 5What is an isotope?Atoms will the same number of protons but different number of neutrons.
- 6What happens if a element's proton change?Changing the number of protons changes the chemical properties of the element and the element itself.
- 7What happens if an element gains or loses a neutron?Changing the neutrons in an element changes the stability of an element. Therefore an element might have an unstable nuclei that is radioactive and decays.
