polar covalent compounds
When two atoms are bonded together but have an unequal sharing of electrons the newly formed molecule is said to be bound by ionic bonds. This unequal sharing is due to differential attractions of the atoms in the molecule to the electrons.
ClF4+ is a polar molecule because it has a net dipole moment due to the unequal sharing of electrons between chlorine and fluorine atoms. This unequal sharing causes the molecule to have regions of partial positive and negative charges.
Ammonia (NH3) involves an unequal sharing of electrons between nitrogen and three hydrogen atoms. What type of bonding does ammonia have?
Ammonia has a covalent bond, where electrons are shared between nitrogen and hydrogen atoms. This type of bond results in the unequal sharing of electrons due to the differences in electronegativity between the elements.
Cyanide (CN-) is a polar molecule because of the unequal sharing of electrons between carbon and nitrogen due to the high electronegativity of nitrogen. The dipole moment created by this unequal sharing results in a polar covalent bond in the molecule.
Yes, PBO2 (lead dioxide) is a polar molecule due to the unequal sharing of electrons between lead and oxygen atoms, resulting in a permanent dipole moment.
When electrons are transferred rather than shared, the result is an ionic compound. If electrons are shared, the result is a covalent compound. This is true even when the sharing is unequal. In a water molecule, the electrons are shared unequally, since they are more attracted to the oxygen atom than they are to the hydrogen atoms, however, the result is still a covalent bond.
Sulfur tetrachloride is a covalent compound due to the sharing of electrons between sulfur and chlorine atoms. In ionic compounds, electrons are transferred from one atom to another.
An atom that has a positive or negative charge due to having unequal numbers of protons and electrons is called an ion. If an atom gains electrons, it becomes a negatively charged ion (anion), and if it loses electrons, it becomes a positively charged ion (cation).
polarity
A molecule with a positive and a negative area is polar. This means it has regions of partial positive and partial negative charges due to an uneven distribution of electrons. Water is a common example of a polar molecule due to its bent shape and unequal sharing of electrons between oxygen and hydrogen atoms.
HIO3 is a strong acid that dissociates in water into H+ and IO3- ions, so it is an ionic compound.
