Atoms And Electron Structure Flashcards
What is an ion?
A charged particle
What is an isotope?
Isotopes are atoms of the same element with different numbers of neutrons
What is relative isotopic mass?
Relative isotopic mass is the mass of an atom of an isotope compared with one-twelfth of the mass of an atom of carbon-12
What is an atomic orbital?
A region that can hold up to 2 electrons with opposite spins
Name the 4 types of orbitals and how many electrons they can hold
S-orbital 2 e-
P-orbital 6 e-
D-orbital 10 e-
F-orbital 14 e-
What is a sub-shell?
A group of the same type of atomic orbitals within a shell
What is electron configuration?
The arrangement of electrons in an atom
State the order of electron configuration
1s 2s 2p 3s 3p 4s 3d 4p
What is relative atomic mass?
Relative atomic mass is the weighted-mean mass of an atom of an element compared with the mass of an atom of carbon-12
