Atom

                                  Atom tih hi Greek thumal ἄτομος"-atomos tih atanga rawn piang a ni a. A awmzia chu "phel darh leh theih tawh loh" tihna a ni.Tihian sawifiah a ni bawk - Atom chu thilthem chemical properties damlam si lo va , a te thei tawp ber hi a ni an ti bawk.Tunah erawh chuan atom mai sawi loh , atom siamtu:pronton leh neutronte thlengin phel darh a lo ni ta a ni.

                     Proton leh neutronte chu electron in an hual vel a. Hemi 3 in phuahkhawm hi Atom kan tih chu a ni.Proton chuan apa nihna(+ charge) a keng tel la, neutron erawh chuan eng nihna (charge) mah a keng lo thung. Chuan , electron hian anu nihna (- charge) a keng leh bawk a ni.Chuvangin anihna ngai takah chuan Atom chu nihna nei lo (electro-neutral) tihna a ni, atom chhunga electron zat leh neucleus chhunga proton awmzat a inan vangin.
                      Atom chhunga particles: electron , proton leh neutron te chuan mahniin rihna(mass), chawlhlai chakna (rest energy) , Spin , charge , nunchhung(amaha kehdarh mai lova a awm theih chhung) etc te a hranin an nei tluah a ni.
