An element being ionized has donated one or more electrons to another element, or has accepted one or more electrons from another element and has thus achieved a octet in it's valance shell. Great electronegativity variances here.
A molecule that is polar is the covalent bond between two, or more elements that have a significant difference in electronegativity so that the electrons shared in the bond(s) spend more time in the element's orbital with the greater electronegativity. This means that element has a slightly negative charge, while the element that has electrons that are shared spend less time in it's orbital has a slightly positive charge. Water is the classic example here of a polar molecule.
Polar lipids form bilayers spontaneously in water while non-polar lipids face towards the "non-polar" side of the cell being non water-soluble.
If the electronegativity difference between two atoms is less than 1.7, then a covalent bond is formed between the two atoms.
the polar one is less stable than the non-polar one
If electronegativity difference is between 0.3 and 1.7 then the bond tends to be is polar. This, however, does not mean that the molecule itself is polar.
the difference in the electronegativity between the two bonded atoms makes the covalent bond polar.
Polar lipids form bilayers spontaneously in water while non-polar lipids face towards the "non-polar" side of the cell being non water-soluble.
If the electronegativity difference between two atoms is less than 1.7, then a covalent bond is formed between the two atoms.
cotton's a fibre polar fleece is a fabric
the polar one is less stable than the non-polar one
the polar one is less stable than the non-polar one
Polar night is when the sun is below the horizon for more than 24 hours, twilight is when the sky is not completely dark despite the sun not being in the sky.
A molecule is polar if there is a difference in electronegativity between two atoms that are bonded together. Since there is no difference in electronegativity between two oxygen atoms, O2 is nonpolar.
Polar covalent. There is a significant difference in electronegativity between C and F.
Polar covalent. There is a significant difference in electronegativity between C and F.
The S-Cl bond is polar. The electronegativity difference between S and Cl is 0.58, which means it is polar.
polar dia is vertical one and equatorial is the horizontal one..............there is a difference as earth is not exactly round right?
Ionic bond: the difference between electronegativities of the atoms is over 2.Covalent polar bond: the difference between electronegativities of the atoms is under 2.Covalent non-polar bond: the difference between electronegativities of the atoms is cca. zero
