		abstract={The purpose of this study was to investigate the student’smisconceptions on atomic structure Senior High School in Labuhanbatu.
The population of study was taken from the senior high school in Labuhanbatu, and the sample of study amounted 177 from five different schools which represented by SMAN 1 NorthRantau (34students), SMAN 2 NorthRantau(35 students), SMAN 3 NorthRantau (32 students), SMAN 1 South Rantau (42 students), SMA SwastaKemalaBayangkara SMA (34 students), The instrument of this study was diagnostic misconception test that had examined the validity by expert in chemistry.
Description analysis was used in analyzing of the data, student’s responses in atomic structure were categorized and it was revealed that students had some misconception about this subject. The majority of student’s misconception in the development ofatomictheory 48.13 %, theelementary particles atomic 14.68 %, therelativeatomic mass 7.79 %, classifyelements intoisotopes, isobars, andisoton19.77 %, theelectronconfigurationandvalenceelectron 48.92 %. The average of senior high school students in Labuhanbatu has misconception 34.38 %.}
