What causes a molecule to have a net dipole movement?
A molecule has a net dipole moment when its overall charge distribution is asymmetric, resulting in a separation of positive and negative charges. This can be due to differences in electronegativity between atoms or to the molecule's geometry when the individual bond dipoles do not cancel each other out.
How might a molecule with two strong bond dipoles have no molecule dipole at all?
A molecule with two strong bond dipoles can have no molecular dipole if the bond dipoles cancel each other out by pointing in exactly opposite directions. For example, in carbon dioxide (a linear molecule), the carbon-oxygen bonds have a large dipole moment. However, because one dipole points to the left and the other points to the right, the dipoles cancel and overall there is no molecular dipole.
What causes a molecule to have net dipole moment?
the presence of a net charge that does not cancel out
How can a molecule be non polar when it consists of atoms that have different electronagativities?
A molecule can be nonpolar if its overall shape is symmetric and the individual bond dipoles cancel each other out. This occurs when the molecule has a symmetrical distribution of charge, despite the presence of atoms with different electronegativities. Examples include carbon tetrachloride (CCl4) and methane (CH4).
What is a molecule with an overall positive or negative charge called?
An ion is a charged molecule. It is either positively or negatively charged due to the amount of electrons it is missing (+) or has extra (-). A charged molecule is said to be Ionized.
Which substance is made up of molecules that are dipoles?
Water is a substance made up of molecules that are dipoles. The oxygen atom in a water molecule has a slight negative charge, while the hydrogen atoms have a slight positive charge, resulting in an overall dipole moment.

How are polarity and molecular symmetry related?
The polarity of a molecule is influenced by its molecular symmetry. Symmetric molecules tend to be nonpolar because any charges or dipoles within the molecule are canceled out by symmetry, while asymmetric molecules are more likely to be polar due to unbalanced distributions of charges or dipoles. Overall, molecular symmetry affects the overall polarity of a molecule.

What is the difference between individual bond polarity and molecular polarity?
bond polarity is the polarity particular bond within a molecule, while molecular polarity is the polarity of the whole molecule. take for example water (H20): you could find the bond polarity of each H-0 bond (polar covalent), or the polarity of the whole molecule together (polar, because the electronegativity of oxygen is higher than the hydrogen atoms)
What is the charge of the SiO2 molecule?
The charge of the SiO2 molecule is neutral, meaning it has no overall positive or negative charge.
What has a slightly negative end although the overall molecule is neutral?
A polar molecule, such as water, has a slightly negative end due to the unequal distribution of electrons between different atoms in the molecule. The overall charge of the molecule, however, remains neutral because the positive and negative charges balance each other out.
What does it mean when a molecule is becomes more negative?
When a molecule becomes more negative, it means that it has gained additional electrons, resulting in an increase in its overall negative charge. This can occur through processes such as electron transfer or the formation of chemical bonds with more electronegative atoms, causing the molecule to exhibit a greater overall negative charge distribution.
