Theoretically, there is no limit to the number of segments that a rattlesnake can have. However, once a rattle has more than a dozen or more segments, it becomes too large to rattle properly and the overall rattle is weakened and usually cannot support a larger number of segments and they break off.

fangs
A rattle snake has no protection from a human,but it might would use his fangs
Under normal circumstances, a rattlesnake has two fangs in the upper jaw towards the front of the mouth and both are capable of injecting venom.
The venom glands are located on either side of the head, behind the eyes.
Rattlesnakes are Venomous with two syringe-like fangs, they bite and inject the venom into their prey and then swallow them whole.
No. The rattle is made up of skin. Each time the snake sheds, another rattle gets added to it.
There is no adjective form of "rattlesnakes" -- there is the adjective "snaky" which means "like a snake", or sinuous (twisting). The singular noun rattlesnake is often used as an adjunct, e.g. rattlesnake den, rattlesnake bite.
A nonvenomous snake bite will usually heave two parallel rows of tiny puncture wounds from the teeth. A rattlesnake bite will usually have two larger puncture wounds from the fangs. See the image of a rattlesnake bite above.
