compare and contrast............?

Question

Compare and contrast a covalent bond to an ionic bond by giving three description of how compounds made with covalent bonds.

Answer 1

My first covalent bond sample is water, H2O, one of the most plenteous substances on Earth. What state do you usually see water in? You have probably seen it in all three basic states: Solid, liquid and gas. The reason why you, or anyone, can see water in the three basic states of matter is that water molecules are held together by a covalent bond.

In contrast, look at table salt or better yet rock salt, NaCl. What state of matter do you usually see salt in? The solid state. And I am betting that you have not seen salt in the liquid or gas state. Do you know why this is? It is because table salt, there are other salts, is held together by an ionic bond. And usually substances held together by an ionic bond are brittle and hard, because in ionic bonds the ions organize neatly into crystals or lattices, and because the ion charges are so neatly organized it takes more heat to split the molecules up so that they are in the liquid or gas phase.

In fact, looking at both substances, shock and awe, water's melting point is 0 degrees Celsius, while salt's is about 1,000 degrees Celsius!!!

Answer 2

Somet things i look at think...huh how could they do that, its wrong and can lead to all sorts of problems. (Like the Youtube advert.) But then again it was more common for a child to find out they were adopted in later in life with no hope of finding their Nfamily because of fears from SOME adoptive parents. (not couple, some even went by their own instincts about and were truthful with their kids from the start.) Is it just that there is a technology brought it out in the open what some people are prepared to do to get a baby. Yeah i think so. Back in the BSE it was all kept under wraps. Even a lot of AP's didn't know what went on hospitals and how babies were taken from their mothers. Some of them were lied to as well. These days there is no real excuse for being unethical (though not being educated of the effects adoption can have on a child) or ignorant when going into adoption. The information is there, so are books and other studies about adoption and what is considered ethical. No 'marketing' was used in our adoption-Family preservation comes first. Its considered the last option, not the first.

Answer 3

covalent bonds the electrons are shared and ionic bonds electons are taken from one atom and given to another.
