What happens to the valence electrons in a polar covalent bond?

Answer 1

Polar bonds are bonds between atoms that have a difference in electornegativities. the more electronegative atom pulls the electrons closer to itself making it semi positive while the other atom in the bond becomes semi neg. one might ask why does the more electronegative atom just take the electron, the answer is because the two atoms share the electrons to fill there outer shell (octet rule). bonds weather polar or not are formed in order to lower energy states and make the atom more stable.

Answer 2

a) Must include a metal and a nonmetal

b) Must be of different elements

c) Are always of the same element

d) Are always two metals

Need Answer! :(

D) Are always two metals.

a) is for ionic compounds

b) is for nonpolar covalent bonds

c) same as nonpolar covalent bonds

b) Must be of different elements:)

Answer 3

Covalent bonds are formed between two non-metals. For example, CH4, commonly known as methane, is a covalent compound. These compounds are formed by sharing of valence electrons. Covalent compounds formed by carbon and hydrogen only are called hydrocarbons.

Answer 4

A polar covalent bond is created when one atom in a bond is more electronegative than the other. What this means is that the electrons from that bond have a greater draw to the more electronegative atom than the other. Since electrons tend to move around quite a bit within the molecular orbitals that are formed between two atoms, what is happening to the electrons is that over time they are spending more time on the electronegative atom than on the less electronegative atom.

Answer 5

The charge of the molecule as a whole in unbalanced. What this per atom is that the concentration of electrons will probabilistically be more common in one place and less common in another because of how the electrons are shared.

Answer 6

In a polar covalent bond, the valence electrons are unequally shared between the atoms involved. This causes a partial negative charge on one atom and a partial positive charge on the other atom, leading to a dipole moment within the bond.

Answer 7

If you consider the covalent bond to be an electron cloud sitting between two atoms in a polar bond the electron cloud is closer to the more electronegative element.

Answer 8

They must be of different elements.
