I don't understand what makes a covalent bond "polar." What exactly is polarity?

1 answer:

5 0

Say you have a bond A-B.

Even though in this bond each atom shares electrons, one might attract electrons more than another. If one atom, A for instance, attracts those electrons way better than B, then the bond will be polar, and the electronic cloud will be more important around A than around B, which gives chemical properties to the molecule.

Why does a raindrop accelerate as it falls to the earth?

allochka39001 [22]

Acceleration is the rate at which an object changes its speed. When a raindrop is falling down from the clouds due to gravity, the veloicty is pretty much fast, however air resistance comes in action and slows the droplet down... it gives it a constant speed until it hits the ground

Which of the following is a correct lewis structure for sulfur dioxide, so2?

pshichka [43]

The correct Lewis structure of SO2 is the Lewis structure that shows all the 12 valence electrons in the molecule.

A Lewis structure shows the number of valence electrons on the valence shell of all the atoms in a compound. The electrons are shown as dots around the symbol of each element or a dash to indicate shared electrons in a covalent bond.

Looking at the Lewis structure of SO2 attached to this answer, we can see the twelve valence electrons in the molecule and how they are distributed around each atom as shown.
