Considering when most of different atoms combine together , the covalent bond and the electrovalent bond are concomitant
2.
( c ) the total energy of manganate - oxides materials decreases after intercalation lithium . the electrovalent bond weakens and the covalent bond strengthen between manganese and oxygen due to ion polarization effect , which makes the spinel structure more stable
3.
By home analyzing the experiment result , we think that the covalent bond is more than the electrovalent bond in y - fe _ ( 2 ) o _ ( 3 ) crystallites . it is the dominating reason that the dependence of y - fe _ ( 2 ) o _ ( 3 ) crystallites grin size on lattice constant is differ from one of the ionic crystallites
परिभाषा
a chemical bond in which one atom loses an electron to form a positive ion and the other atom gains an electron to form a negative ion पर्याय: ionic bond, electrostatic bond,
