can some one please help me out i need to change 02 sensor bank one sensor 2 bank 1 is on the right side?????????? thanks

Out of curiosity, why do you think you need to change one particular O2 sensor? Many of the O2 sensor codes just indicate that the sensor is reporting a particular parameter of interest, not necessarily that the sensor itself is bad. I'd hate for you to invest in new sensors only to find that the real cause is a $3 vacuum hose or something.

But, to your original question, yes, bank 1 is the bank on the passenger side of the car. Sensor 2 is the sensor after the catalytic converter.

i check and the code was p0136 and it says 02 sensor bank 1 sensor 2 does that not mean the sensor is bad if i am wrong i am all ears thanks

That code does not necessarily mean the sensor is bad. It could be, but the code could also be due to a leak in the exhaust near the sensor, a wiring issue for the sensor, or a dirty/corroded connector in the O2 sensor circuit. If you have a scan tool that can monitor the O2 sensor datastream it may help you determine if it's likely a wiring issue versus a sensor issue.
