Electronic Structure 1 Flashcards
What is a positively charged subatomic particle found in the nucleus?
Proton
What is a neutrally charged subatomic particle found in the nucleus?
Neutron
What is a negatively charged subatomic particle found orbiting the nucleus?
Electron
What is an energy level occupied by electrons?
Shell
What is a subshell within an energy level that can only hold two electrons?
Orbital
What is the arrangement of electrons in an atom or in a molecule?
Electron configuration
What is the method for filling electron shells. Lowest-energy shells are filled first, and all orbitals are singly occupied before electrons are paired up.
Aufbau principle
What is the distribution of electrons in atomic or molecular orbitals?
Electronic Structure
What is a region of an electron shell which contains all the orbitals of one type?
Subshell
What is a property of electrons which affects how they pair up?
Spin
What is the small, positively charged region at the centre of an atom?
Nucleus
What is an atomic model with protons and neutrons in the nucleus, surrounded by defined electron shells?
Bohr model
