Classifying Bonds
What type of bond is this: Li2O?
Ionic
What type(s) of elements makes a bond covalent?
Non-metal only
What type(s) of elements make a bond Ionic?
Metal and non-metal
What type(s) of elements makes a bond metallic?
Only metal
What is the difference between writing the name for ionic compounds and covalent compounds?
Only covalent compounds use prefixes
What is the geometry for CH4
Tetrahedral
What type of bond is this: PCl2?
Covalent
Do covalent bonds conduct electricity? If so, how?
No they do not conduct electricity
Do covalent bonds conduct electricity? If so, when?
Yes, when dissolved
Do metallic bonds conduct electricity? If so, when?
Yes, in all forms
What would the prefixes be for this compound: P2O3?
Di-phosphate and Tri-oxide
What change causes the molecular geometry to be different from the electron geometry? E.g. water has a tetrahedral electron geometry but bent molecular geometry; why?
Lone pairs. Electron geometry describes how many "things" are around an atom. The molecular geometry describes how many other molecules are around the atom.
What type of bond is this: Ca2Fl?
Metallic
What happens to electrons in a covalent bond?
They are tightly shared
What happens to electrons in an ionic bond?
They transfer electrons
What happens to electrons in a metallic bond?
They are loosely shared
Name this compound: N2S3
