Why is it necessary to scratch the sides of the beaker for crystals to form?
Because i think that this will help form the crystal by getting things off the sides and help the crystal disolve. If not i don't think it is necessary.
How many sides does the hexagonal crystal have?
It depends on the gem all gems are diffrent18 i thinkAmethyst is the violet variety of quartz; its chemical formula is SiO2.The crystaline form is rhombohedralThe rhombohedral system can be thought of as the cubic system stretched along a body diagonal. a = b = c; α = β = γ ≠90°.There are six sides to a pure simple crystal.
How many different systems are crystals classified into?
Seven. They are: Cubic - all angles 90 degrees, all sides equal length Trigonal - all angles 90 degrees, two sides equal and the third unequal Orthorhombic - all angles 90 degrees, no sides equal Hexagonal - two angles 90 degrees and one angle 120 degrees, two sides unequal and the third unequal Trigonal - all angles equal but not 90, all sides equal Monoclinic - two angles 90, one more than 90, and no sides equal Triclinic - no angles equal, no sides equal For a graphical representation of these, see http://en.wikipedia.org/wiki/Crystal_system#Classification_of_lattices
How do you make crystals?
ALUM CRYSTALS you can find alum in a grocery store under 'spices' it is used for pickleingPour 1/2 cup of hot tap water into a clean jar.Slowly stir in alum, a little at a time, until it stops dissolving. Don't add the whole amount - just enough to saturate the water.Loosely cover the jar with a coffee filter or paper towel (to keep dust out) and allow the jar to sit undisturbed overnight.The next day, pour the alum solution from the first jar into the clean jar. You will see small alum crystals at the bottom of the jar. These are 'seed' crystals that you will use to grow a big crystal.Tie nylon fishing line around the largest, best-shaped crystal. Tie the other end to a flat object (e.g., popsicle stick, ruler, pencil, butter knife). You will hang the seed crystal by this flat object into the jar far enough so that it will be covered in liquid, but won't touch the bottom or sides of the jar. It may take a few tries to get the length just right.When you have the right string length, hang the seed crystal in the jar with the alum solution. Cover it with the coffee filter and grow a crystal!Grow your crystal until you are satisfied with it. If you see crystals starting to grow on the sides or bottom of your jar, carefully remove your crystal, pour the liquid into the clean jar, and put the crystal in the new jar. Other crystals in the jar will compete with your crystal for alum, so it won't be able to get as big if you let these crystals grow.Tips:You can use sewing thread or other string instead of nylon fishing line, but crystals will grow on the entire length of the submerged string. Crystals don't adhere to nylon, so if you use it, you can get bigger, better crystals.Alum is an ingredient used to make pickles. It makes them crispy.What You Need:1/2 c hot tap water2-1/2 T alumnylon fishing linepencil, ruler, or knife2 clean jarsspooncoffee filter/paper towelFOR SUGAR CRYSTALS:What You Need:1 cup water3 cups table sugar (sucrose)clean glass jarpencil or butter knifestringGather your materials.You may wish to grow a seed crystal, a small crystal to weight your string and provide a surface for larger crystals to grow onto. A seed crystal is not necessary as long as you are using a rough string or yarn.Tie the string to a pencil or butter knife. If you have made a seed crystal, tie it to the bottom of the string. Set the pencil or knife across the top of the glass jar and make sure that the string will hang into the jar without touching its sides or bottom. However, you want the string to hang nearly to the bottom. Adjust the length of the string, if necessary.Boil the water. If you boil your water in the microwave, be very careful removing it to avoid getting splashed!Stir in the sugar, a teaspoonful at a time. Keep adding sugar until it starts to accumulate at the bottom of the container and won't dissolve even with more stirring. This means your sugar solution is saturated. If you don't use a saturated solution, then your crystals won't grow quickly. On the other hand, if you add too much sugar, new crystals will grow on the undissolved sugar and not on your string.If you want colored crystals, stir in a few drops of food coloring.Pour your solution into the clear glass jar. If you have undissolved sugar at the bottom of your container, avoid getting it in the jar.Place the pencil over the jar and allow the string to dangle into the liquid.Set the jar somewhere where it can remain undisturbed. If you like, you can set a coffee filter or paper towel over the jar to prevent dust from falling into the jar.Check on your crystals after a day. You should be able to see the beginnings of crystal growth on the string or seed crystal.Let the crystals grow until they have reached the desired size or have stopped growing. At this point, you can pull out the string and allow the crystal to dry. You can eat them or keep them. Have fun!If you are having trouble growing sugar crystals, you may want to try some special techniques. A video tutorial showing how to make rock candy is available, too.Tips:Crystals will form on a cotton or wool string or yarn, but not on a nylon line. If you use a nylon line, tie a seed crystal to it to stimulate crystal growth.If you are making the crystals to eat, please don't use a fishing weight to hold your string down. The lead from the weight will end up in the water -- it's toxic. Paper clips are a better choice, but still not great.
What is a face centered cubic crystal?
A face-centered cubic unit cell is a cube. All sides are the same length and all face perpendicular to each other, with an atom at each corner and an atom in the middle of each face of the cell.
How many faces does a hexagonal crystal have?
If a mineral belongs to the hexagonal crystal group, then its crystals have six sides.
Does a quartz crystal always have 6 sides?
Most Quartz crystals have 6 sides, But some of them have more or less. Hope that helped:)
Why is it necessary to scratch the sides of the beaker for crystals to form?
Because i think that this will help form the crystal by getting things off the sides and help the crystal disolve. If not i don't think it is necessary.

How do crystals grow?
the first stage is when certain chemicals dissolve into water, then the water starts to evaporate and the crystals form columns that normally have either 4, 6 or 8 sides. sometimes little spikes of crystal grow out of the crystals even when there's no water there.
How many sides does a crystal have?
The number of sides a crystal has depends what minerals or elements make up the crystal. A cubic crystal has 6 sides. A hexagonal crystal with flat ends has 8. A hexagonal crystal with pointed ends has 18.
What is a crystal and how many faces and sides?
A crystal is a polyhedral shape. The number of faces (which means the same thing as sides) depends on the crystal.
Does all crystals have eight square sides?
Some crystals have 6 sides while others have 4. Some of the four sided are rhombuses
How many sides does the aquamarine's crystal have?
28 sides
What is the difference between positive crystals and negative crystals?
Normally crystals do not have electrical charge.A few types of crystals (e.g. quartz) will develop an electrical charge across them when placed under mechanical stress. This property is called piezoelectricity. But the positive and negative charges are on opposite sides of one crystal, not on two different crystals.Perhaps you were actually thinking of something that has nothing to do with science or electricity when you asked this question.
If a mineral belongs to hexagonal crystal group how many sides does it have?
It has eight sides.
How many sides does an ice crystal have?
6
