Ini merupakan senarai unsur kimia, yang disusun mengikut jisim atom relatif, atau lebih tepat berat atom piawai, (isotop paling stabil bagi unsur buatan unsur) dan kod warna mengikut jenis unsur. Setiap nombor atom unsur, nama, simbol unsur, dan kumpulan serta kala bagi jadual berkala turut diberikan. Nombor dalam kurungan memberikan ralat dalam "pernyataan ringkas" yang ditakrifkan oleh IUPAC merujuk kepada "ralat piawai diberikan dalam kurungan bersebelahan dengan angka bererti yang paling kecil baginya ", cth., 1.00794(7) menunjukkan 1.00794 ± 0.00007. Bagi unsur buatan, bilangan nukleon bagi isotop paling stabil disenaraikan dalam kurungan [] sebagai jisim atom.
