What type of chemical bond forms when atoms with high electronegativity react with atoms with low electronegativity?
If the elecrtronegativity difference is greater that 1.7 it is an ionic bond. If it is lower that 1.7 but greater than 0 it is a polar covalent bond. If it is equal to 0 it is a pure covalent bond.
What is a polar covalent bond forms when two atoms?
A polar covalent bond is formed when the difference between electronegativities of two atoms is 0,4 to 1,7.
What do electrons do for polar covalent?
When the difference of the electronegativities of the atoms is significanct the bond is covalent polar. The electrons are of course shared.
What type of bond if formed when electrons are shared?
Covalent bonding. It can be two types - polar covalent or nonpolar covalent. In polar covalent bonding, atoms do not share electrons equally. In nonpolar covalent bonding, atoms share electrons equally.
What is the difference between polar and nonpolar molecules?
Polar covalent molecule is where one element in the bond is more electronegative and holds the shared electrons closer to itself. Non polar covalent bonds is where they're evenly between each element.
What does the presence of a polar covalent bond show about the electronegative of its two atoms?
The meaning is a significant difference of electronegativity.
How does the presence of an electronegative atom in a molecule contribute to the formation of a polar covalent bond?

What does the presence of of a polar covalent bond show about the electronegativeities of its two atoms?
The electronegativities of the two atoms are not equal.
What does the presence of a polar covalent bond show about the electronegativities of its atoms?
(apex!) the electronegativities of the two atoms are NOT equal.
What does a non polar covalent bond show about the electronegative of its two atoms?
The electronegativities of it's two atoms are similar.
What is the meaning of polar in polar covalent and non-polar covalent bond?
Firstly Polar means an UNEQUAL distribution of electron density within a covalent bond. This is because two atoms of DIFFERENT elements join with a covalent bond. However one atom maybe more electronegative than the other, this means the more electronegative atom has a 'stronger' ability to attract the electron pair within the covalent bond towards itself. So the electron 'cloud' surrouding the two atoms becomes distorted towards the more electronegative atom. This causes the more electronegative atom to become Delta - and the atom with the lower electronegativity to take on a partially positive charge Delta + . So the greater the difference in electronegativity between the two atoms the more polar the covalent bond is.
Is the covalent bond of SiC polar or non-polar?
Polar covalent. C is more electronegative than Si.
What type of chemical bond forms when atoms with high electronegativity react with atoms with low electronegativity?
If the elecrtronegativity difference is greater that 1.7 it is an ionic bond. If it is lower that 1.7 but greater than 0 it is a polar covalent bond. If it is equal to 0 it is a pure covalent bond.
What happens between atoms in covalent and polar covalent bonds?
covalent bonds is the sharing of electrons between two atoms. polar covalent bonds occurs when one atom is more electronegative than the other and therefore pulls the electron more closely to its atom (the electron is still being shared)
What is water an example of polar molecule?
A covalent bond is a bond where atoms share electrons. For water the structure is H-O-H. The electronegative difference between the H and O allows them to be polar covalent.
The water molecule has a dipole with the negative portion?
Water (H20) is a polar covalent molecule with two highly electronegative oxygen atoms. The electronegative oxygen atoms create a dipole moment, and are also cause H20s bent shape.
What type of covalent bond is formed in nitrogen molecule?
Nitrogen will form a non polar bond to another nitrogen, a polar bond to other atoms with different electronegativity. In NH3 N is the most electronegative, in NF3 it is F that is the most electronegative.
