ions
polar
positive ions
negative ions

non-polar
molecule
Make a general statement about what polyatomic ions are
Polyatomic ions are ions
They have chemical bonds
A polyatomic ion is a positively or negatively charged, covalently bonded groups of atoms
Make a general statement about why ionic compounds are neutral
Ionic compounds are neutral because their oxidation number is the same as the charge of the ion
They have a good oxidation number
Oppositely charged ends
Make a general statement about what types of molecules are non polar
Molecule that ( shares electrons equally) do not have oppositely charged ends
Non Polar molecules are molecules
Molecules
Compare electron sharing in polar and nonpolar molecules , defining your terms as you go ....
Polar molecules: unequal sharing of electrons resulting in a slightly positive end and a slightly negative end , although the overall molecule is neutral
Non polar molecules: molecule that ( shares electrons equally ) does not have oppositely charged ends
Make up unequal sharing of electrons between two atoms has been compared to a tug of war , in which he larger team pulls the knot in the middle of the rope closer. Make up another metaphor for unequal sharing that makes sense to you and explain what it means
!!!!!!!! STUDY THIS QUESTION !!!!!!!!!!
In a teeter totter, if the weight is not balanced equally the person who is the lightest sits high up in the air , while the person who weighs the heaviest sits closets to the ground due to the unbalance of weight being shared between two people . In comparison the unequal sharing of electrons in polar and non polar bonds/ molecules. this shows how if one side of the teeter totter ( resembling an atom) has more weight ( electrons) than the other side, than the teeter totter (atoms electron configuration) will not be equal
I´m not sure
