Fluorine Facts
Fluorine has this many valence electrons
7
Metals do this with electrons to become positive ions
lose electrons
A lattice is a repeating 3D arrangement of these
ions
Water does this to ionic compounds, pulling ions apart
dissociate them
Atoms bond to achieve this number of electrons in their outer shell
8
Fluorine is in this group on the periodic table
Group 7A
gain electrons
crystal lattice
A solution that contains free-moving ions is called this
electrolyte
This rule explains why atoms gain, lose, or share electrons
octet rule
Two Fluorine atoms cannot form this type of bond because neither wants to lose an electron
An ionic bond
Ionic bonds form because these two types of ions attract each other
positive and negative ions
Table salt is an example of this type of structure
ionic lattice
A salt-water solution can do this because ions move toward electrodes
conduct electricity
Covalent bonds form when atoms do this instead of transferring electrons
share electrons
Instead of transferring electrons, two Fluorine atoms do this to form F2
This term describes the strong attraction between ions in an ionic compound
electrostatic force
Name one example of a lattice (from our study guide)
NaCl or MgO
In a conductivity model, a light bulb lights up when this happens
ions complete the circuit
Ionic bonds form when electrons are transferred between these two types of elements
metals and nonmetals
Fluorine wants to gain exactly this many electrons to become stable
1
Group 1 metals lose this many electrons; Group 2 metals lose this many electrons
1 and 2
This force holds the lattice together
electrostatic attractions
A solution conducts electricity only when these charged particles can move
ions
Atoms with almost full valence shells, like O and I, tend to do this
gain electrons
