I-Kalzium wuhlelo olukukhombisa i-Periodic Table of Elements. Ungasebenzisa i-Kalzium ukucinga ulwazi mayelana nezakhi noma ukufunda amaqiniso ngethebula le-periodic. Inikeza ukubuka konke kwedatha ebalulekile (njengamaphoyinti ancibilikayo, ukuhambisana kwama-electron, ukungabi nalutho kwe-electron, ukucushwa kwama-electron, i-radii, mass, ionisation energy), ithebula le-isotopu, nokubukwa okunemibala ehlukene kwethebula le-periodic (ukuhlukaniswa kwamabhulokhi ahlukene, isifanisi sonyaka, isifanisi sezinga lokushisa). Iqukethe amathuluzi okubona ngeso lengqondo imigqa ye-spectral ye-elementi ngayinye, isibali sesisindo se-molecular, umhleli we-molecule ye-3D, kanye nesixazululi se-equation sezinkinga ze-stoichiometric.
