58 - True

59 - True

60 - Fe and O

61 - Sr and F

62 - both ionic and covalent bonds

Hope this helps!

Answer:

57) True

58) True

59) True

60) Fe and O

61) Sr and F

62) both ionic and covalent bonds

Explanation:

57) True: The sharing of valence electrons between atoms forms covalent bond and transferring of electrons forms ionic bond.

58) True: The bond between to non metals is always covalent bond.

59) True: The bond between a metal and a non metal is ionic bond. Here lithium is a metal and fluorine is non metal.

60) Fe and O: the bond between a metal and non metal is ionic bond. Here iron is a metal and oxygen is a non metal.

61) Sr and F: he bond between a metal and non metal is ionic bond. Here Sr is a metal and F is a non metal.

62) both ionic and covalent bonds:

With non metals a non metal forms covalent bonds

With metals a non metal forms ionic bonds.
