No, snowflakes actually do have the shape of a flake like we can see in drawings.
Like fingerprints, each snowflake is unique.
To see the exact shape and the uniqueness of the flake, one would have to look at it through a microscope.

No, they are not. They are small crystaline like masses that take various shapes in which no 2 are ever alike. A bunch of snowflakes in the thousands would comprise snow.

No, actually. Snowflakes are actually tiny condensed pieces of ice! They are much more complex than that, even. Clouds (which are gaseous water) condense and fall down to the earth as rain; if it's cold enough, the tiny droplets of water will condense even further to form intricate ice crystals, which are light and small enough to come down as white flakes.

A snowflake is an aggregate of ice crystals that forms while falling in and below a cloud

flakes of ice and the scientists say there are no 2 snowflakes exactly alike. which is amazing

They are ice crystals formed by water droplets and vapor. Some are much more rare then others. But here are a few common types of snowflakes.
A hexagonal prism is the most basic snow crystal geometry (see the Snowflake Primer). Depending on how fast the different facets grow, snow crystal prisms can appear as thin hexagonal plates, slender hexagonal columns (shaped a lot like wooden pencils), or anything in between. Simple prisms are usually so small they can barely be seen with the naked eye.
Stellar Plates
These common snowflakes are thin, plate-like crystals with six broad arms that form a star-like shape. Their faces are often decorated with amazingly elaborate and symmetrical markings.
Stellar plates often show distinctive ridges that point to the corners between adjacent prism facets. When these ridges are especially prominent, the crystals are called sectored plates.
The simplest sectored plates are hexagonal crystals that are divided into six equal pieces, like the slices of a hexagonal pie. More complex specimens show prominent ridges on broad, flat branches.
Stellar Dendrites
Dendritic means "tree-like", so stellar dendrites are plate-like snow crystals that have branches and sidebranches. These are fairly large crystals, typically 2-4 mm in diameter, that are easily seen with the naked eye.
Fernlike Stellar Dendrites
Sometimes the branches of stellar crystals have so many sidebranches they look a bit like ferns, so we call them fernlike stellar dendrites. These are the largest snow crystals, often falling to earth with diameters of 5 mm or more. In spite of their large size, these are single crystals of ice -- the water molecules are lined up from one end to the other.
Some snowfalls contain almost nothing but stellar dendrites and fernlike stellar dendrites. It can make quite a sight when they collect in vast numbers, covering everything in sight.
The best powder snow, where you sink to your knees while skiing, is made of stellar dendrites. These crystals can be extremely thin and light, so they make a low density snowpack.
Hollow Columns
Hexagonal columns often form with conical hollow regions in their ends, and such forms are called hollow columns. These crystals are small, so you need a good magnifier to see the hollow regions.
Note how the two hollow regions are symmetrical in each column. Sometimes the ends grow over and enclose a pair of bubbles in the ice, as seen in the last picture on the right.
Needles
Needles are slender, columnar ice crystals that grow when the temperature is around -5 C (23 F). On your sleeve these snowflakes look like small bits of white hair.
One of the amazing things about snow crystals is that their growth changes from thin, flat plates to long, slender needles when the temperature changes by just a few degrees. Why this happens remains something of a scientific mystery.
Capped Columns
These crystals first grow into stubby columns, and then they blow into a region of the clouds where the growth becomes plate-like. The result is two thin, plate-like crystals growing on the ends of an ice column. Capped columns don't appear in every snowfall, but you can find them if you look for them.
The first example at right shows three views of a capped column. The first view is from the side, showing the central column and the two plates edge-on. The other two views show the same crystal from one end, with the microscope focused separately on the two plates.
Double Plates
A double plate is basically a capped column with an especially short central column. The plates are so close together that inevitably one grows out faster and shields the other from its source of water vapor. The result is one large plate connected to a much smaller one. These crystals are common -- many snowflakes that look like ordinary stellar plates are actually double plates if you look closely.
The first picture at right shows a double plate from the side. The second picture shows a double plate with the microscope focused on the smaller plate. In the third picture, note the slightly out-of-focus hexagon that is about one-sixth as large as the main crystal. This hexagon is the second side of a double plate, connected to the main plate by a small axle.
Classifying Snowflakes
How does one classify snowflakes? It's not so easy, because how you divide the different types is somewhat a matter of taste. There is a good analogy with breeds of dogs. The definition of different breeds is decided upon by a committee of people, and really one can make up as many breeds as one wants. And no matter how many different breeds you define, some dogs will be mixed, not belonging to any one breed.
Snowflakes do come in different types, and you need to give them names if you want to talk about them. But there will never be a precise way to define the different types. I prefer the 35 types shown at the top of this page, but others have come up with alternate classifications schemes. Some of these are shown below.
Hope this helps

No they are crystals of ice. Do a google image search for snowflakes and you'll see what I mean.

they are crystals of ice shaped like stars..and believe it or not neither is the same as the other...they are really beautiful and when you see them you think of the beauty of our Universe big and small
happy new year
