Part A What is meant by the term polar covalent bond? O A polar covalent bond is a type of chemical bond formed through an electrostatic attraction between two oppositely charged ions. A polar covalent bond is the attractive interaction of a hydrogen atom with an electronegative atom, such as nitrogen, oxygen or fluorine, that comes from another molecule or chemical group A polar covalent bond is a covalent bond in which electrons are shared unequally, being more attracted to...

How do you tell the polar or non-polar covalent bond using the way of sharing electro shared, non-polar; unequally shared, polar) 4. How do you tell the ionic bond or covalent bond by the types of elements combined? nonmetal ionic; nonmetal-nonmetal: covalent) In gener 5. How do you know the number of valence electrons does an element have? (Based on the periodic...
In a covalent bond, the valence electrons from atoms are: a. shared b. transferred to the less metallic element c. transferred to the more metallic element d. gained by the anion e. gained by the cation
1. Polar covalent bonds are formed when the electrons in the bond are not shared equally between the two nuclei. Which one of these molecules through polar bonds? a. molecular oxygen b. methane c. a hydrocarbon d.
