Valence Electrons
How many valence electrons does Mg have?
2
Draw a Bohr Model for Hydrogen.
1 ring, 1 electron
What does it mean for an electron to be in an "excited state"?
The electron absorbed a specific amount of energy and is temporarily in a higher energy level than it's ground state.
On the outer most ring
What element has a Bohr model with two orbitals and 7 valence electrons?
Fluorine
What is an electron's ground state?
An electron's ground state is the stable shell that an electron can be found in.
An electron must jump to a higher energy level, and then release that energy as a photon when it returns to it's ground state.
How many valence electrons does Cl have?
7
Draw a Bohr Model for Aluminum.
3 rings, 13 electrons, 3 valence electrons
What is a valence Electron
Electrons in the outermost shell in a Bohr model.
Which element has four emission spectra lines?
How many valence electrons does He have?
2
Draw a Bohr Model for Calcium.
What is a quantum?
The specific amount of energy between electron orbital levels.
Each colored line in an atomic emission spectrum corresponds to:
an electron transition at that specific energy.
