i just want to know how common it is for a chip to be damiged by static and if the chip chud be damiged by heat if it was still tuchable without burning your hand and the max storage temp is 150 degrees C.
Speaking in general, yes ICs (integrated circuits, or "chips") can be damaged by static just from handling
and can also be damaged by heat even when you can still safely touch it without burning yourself.
Some ICs are much more robust than others for both static and temperature but a good rule of thumb is if you don't know if its sensitive, treat it as if it is sensitive.I would recommend investing in ESD (electrostatic discharge) protection such as a wrist strap and an ESD mat.

I have to disagree here!If you can hold an object without feeling pain, the temp will be less than 50°C to 60°C tops.Soldering the leads, the temp. won't get much over 100° at the crystal at that point.
123laurens <- May I ask how old you are?
Also, what country are you from?
Yes, but an ESD damage can be very hard or even impossible to actually credit to ESD, since the damage could be eg. a weakening of a trace in the crystal, showing up as damage a week or a few years from when it actually happened.
If any of the black casing of the chip is melted, there's a pretty good chance that the electronics inside are fried too.
14,but i have made 3D games(with game maker,almost purely in code,GML(Game Maker Langwige,lol)understand bacic consepts of electronics and always dreamed of building a robot.(my current goal)
South Africa,quite remote so shipping costs a lot
good,im going to get a different microcontroller when the time komes,and raize inuf money for a new one. i didnt see a spark.
thanks for the comments so far,im just a little new to soldering on a perf board,i usualy solder wires to swiches or patentometers or lamps(or this HUGE capacitor i found in an old TV set) and soldering briges seems imposable. at least that expensive chip seems ok.
[...] but i wanted to get the ATmega328 as it has more memory,and i thout it whud be better in the long run.
