Salt crystals are formed when sodium and chlorine bond together via a shared electron and these sodium and chlorine molecules bond with other sodium and chlorine molecules. Water dissolves the connection between the sodium and chlorine atoms, but when the water evaporates, the connection can re-establish itself.Continue Reading
Salt is made up of the elements sodium and chlorine, while water is made of hydrogen and oxygen. The bond between sodium and chlorine is weak enough that when the stronger hydrogen and oxygen combination is introduced, the sodium and chlorine bond can't maintain its integrity. The water molecules isolate the salt molecules from each other for as long as water is present. When the water evaporates, the sodium and chlorine molecules can come back together, allowing salt to grow in its naturally forming cubic crystals on any surface porous enough to allow the molecules.
A crystal is any hard, solid substance made of molecules bonded together in a specific repeating pattern, typically with straight edges and flat surfaces. Diamond and graphite, which are two different crystalline structures of carbon, are commonly known crystals. Geodes are a type of crystal formed when bubbles are trapped in melted rock after a volcanic eruption, while snow is crystallized water.Learn more about Chemistry
When sodium and chlorine combine, chlorine gains an electron and sodium loses an electron. As a result, the chlorine gains a negative charge and the sodium gains a positive charge. This process is known as ionic bonding.Full Answer >
Magnesium has a very energetic combustion reaction with oxygen, where two atoms of magnesium bond with one molecule of oxygen gas to form two molecules of magnesium oxide. This reaction is extremely exothermic, releasing a great deal of heat and light, which is why magnesium fuses are used to initiate reactions such as the thermite reaction, and magnesium is used in flares for high visibility. The reaction of magnesium to oxygen is so energetically favorable that burning magnesium can steal the oxygen from both water and carbon dioxide, making these common methods of dousing flames ineffective to stop magnesium combustion.Full Answer >
In chemistry, adhesion refers to the tendency of unlike molecules to bond with one another, while cohesion refers to the attractive force between molecules of the same type. Surface tension, which is an essential property of water, illustrates the relationship between adhesion and cohesion.Full Answer >
Some recipes for growing crystals include mixing three tablespoons of borax with a cup of boiling water or mixing equal parts Epsom salt and hot tap water. Salt crystal geode recipes call for only hot water, salt and an eggshell, while recipes that mix copper sulfate and hot water produce crystals that are vivid blue in color.Full Answer >
