P is in the middle with a Cl on 3 out of 4 sides. Between each P and Cl there is one pair of electrons. There is one unbonded pair of electrons on the P.

If there were two bonds connecting a pair of elements (ie. O2) , what do we call the bonds?
What are double covalent bonds
200
is H2 polar, nonpolar or ionic
nonpolar
200
write the structural formula for H2.
What is H-H
200
How many valence electrons in SO3-2?
What is 20
200
Write the structural formula for PCl3
P is in the middle with a Cl on 3 out of 4 sides. Between each P and Cl there is a single bond. There is one unbonded pair of electrons on the P.

How do we decide how many electrons to place on the dot diagram?
What is the number of valence electrons?
300
having electrical or magnetic polarity means?
What is polar
300
why dont i need to put extra electrons around my formula for H2, which is H-H?
Hydrogen only wants 2 electrons and the bond signifies that it already has two
300
What is the hybridization of CH4?
What is SP3
300
Write the electron dot diagram for As2.
What is As:::As there will be two unbonded electrons left on each As.
300
What would we call a bond with three lines together in the structural formula?
What are triple covalent bonds?
400
no separation of charge, so no positive or negative poles are formed
What is nonpolar
400
How many electrons are represented with the "-' symbol when writing the structural formula?
two electrons
400
What is the hybridization of CO2?
What is SP
400
Write the structural formula for PCl3
As(triple bond/three lines) as there will be two unbonded electrons left on each As.
400
Do covalent bonds share electrons or transfer electrons?
What is to share electrons?
500
is H2S polar, nonpolar or ionic ?
polar
500
Is H2 polar or nonpolar?
What is nonpolar
500
What is the hybridization of SO2?
SP2
500
Why don't we just put 5 bonds between the As atoms?
Each As can only hold 8 valence electrons and 5 bonds would make 10.
