Arrangement Of Electrons In The Atom Flashcards
What is an energy level?
An energy level is defined as the fixed energy value that an electron in an atom may have
What is the ground state?
The ground state of an atom is one in which the electrons occupy the lowest available energy levels
What is the excited state?
The excited state of an atom is one in which the electrons occupy higher energy levels than those available in the ground state.
What does Heisenberg’s Uncertainty Principle state?
It states that it is impossible to measure at the same time both the velocity and the position of an electron
What is an orbital?
An orbital is a region in space within which there is a high probability of finding an electron
What is a sublevel?
A sublevel is a subdivision of a main energy level and consists of one or more orbitals of the same energy
