Natiri (pia: sodiamu) ni elementi na metali alikali yenye namba atomia 11 kwenye mfumo radidia na uzani atomia 22.98976928. Alama yake ni Na. Jina latokana na chumvi asilia ya natroni alimotambuliwa. Natiri inapatikana duniani ndani ya chumvi cha kawaida cha NaCl (kloridi ya natiri) kinachopatikana kwa wingi katika maji ya bahari.
Kiini cha atomi chake kina nyutroni 11. Kuna isotopi moja tu ya kudumi ni 23Na. Peke yake ni metali laini nyeupe inayotunzwa katika mafuta kwa sababu inameyuka haraka.
Natiri tupu hutunzwa ndani ya mafuta ili kuzuia kumenyuka kwake
