penemuan unsur kimia yang diketahui sekarang ditampilkan secara kronologis di sini.
unsur kimia yang ditampilkan umumnya berdasarkan urutan tiap-tiap unsur tersebut pertama kali dinyatakan sebagai unsur murni, karena tanggal persis penemuan sebagian besar unsur tidak dapat secara akurat ditentukan.
beberapa unsur-unsur pertama tidak memiliki catatan tertulis.
albertus magnus di percaya sebagai orang pertama yang memisahkan unsur ini.
pertama kali diuraikan secara ilmiah oleh tholden
abada ke 15?
mungkin telah dijelaskan dalam tulisan dikaitkan dengan basil valentinus, definitif diidentifikasi oleh claude franois geoffroy pada 1753
diidentifikasi sebagai logam unik oleh paracelsus
ditemukan oleh hening brand, namun baru diuraikan oleh robert boyle
ditemukan secara tepisah oleh antonio de ulloa (dipublikasikan tahun 1748) dan charles wood.
sejak abad ke 16 telah diketahui di amerika selatan pada tambang biji emas.
axel fredrik cronstedt
dipisahkan dan diuraikan oleh henry cavendish, namun baru diberi nama oleh antoine lavoisier
karena keyakinannya dalam phlogiston, priestley tidak menyadari bahwa ia telah menyiapkan elemen baru, dan berpikir bahwa ia telah berhasil mempersiapkan udara bebas dari phlogiston ("de-phlogisticated udara").

dinamakan setelah baru ditemukan [asteroid []], ceres.
ditemukan hampir bersamaan di dua laboratorium, meskipun kemudian menunjukkan bahwa cerium berzelius dan hisinger itu sebenarnya merupakan campuran dari cerium, lantanum dan disebut didymium.

carl gustaf mosander
discovered when mosander showed that the cerium isolated in 1803 by berzelius was actually a mixture of cerium, lanthanum and so-called didymium.
