No they do not. I don't think atoms have a positive or negative charge at all because atoms have the same amount of protons and electrons. Ions are a different story, however...
This site explains the charges of atoms and ions better then I can, check it out.

An atom may be neutral, or it may have a positive or a negative charge. If it has a charge, it is called an ion.
No, not all matter has a negative or positive charge. Matter can be neutral, meaning it has an equal number of positive and negative charges, such as in most atoms. Charged particles exist in matter, such as electrons with a negative charge and protons with a positive charge.
No, it is not true that all atoms have a positive charge. Atoms are composed of protons, which have a positive charge, and electrons, which have a negative charge. In a neutral atom, the number of protons equals the number of electrons, resulting in no overall charge. However, some atoms can lose or gain electrons, resulting in charged ions, which can be either positively or negatively charged.
A polyatomic ion is held together by covalent bonds between atoms. They can be either positive or negative. For example, the ammonium ion, NH4+, has a positive charge, and the sulfate ion, SO42-, has a negative charge.
atoms often gain or lose electrons,which causes them to have a temporary negative or positive charge.
Atoms are neutral. Ions can be charged, either positive or negative.

Positive atoms: cations. Negative atoms: anions
An atom with positive charge is cation.An atom with negative charge is anion.

a zewithalarion shows poth positive and negative; go figure...

A polyatomic ion is a group of atoms with a charge.
Yes, if they are ions
atoms often gain or lose electrons,which causes them to have a temporary negative or positive charge.
In a water molecule, the hydrogen atoms have a partial positive charge. This is because the oxygen atom is more electronegative than hydrogen, pulling electron density towards itself and creating a partial negative charge on the oxygen and a partial positive charge on the hydrogen atoms.
