Compléter Chemical bondingVersion en ligne Chemical bonding in elements and compounds par Can Akpolat 1 Water diatomic noble positive Ion outer giant metals stable metallic Alloys lose covalent is formed from hydrogen and oxygen . Chemical bonding involves the electrons of each atom . Elements such as oxygen ( O2 ) and hydrogen ( H2 ) consist of molecules . The electron arrangements of the gases are most stable and so their atoms do not combine with each other . Most elements are . Metallic elements are held together by bonding , which results in metallic lattices . Non - metallic elements are held together by bonding or exist as separate atoms ( the noble gases ) . Covalent bonding results in simple molecules or molecular lattices . such as solder and brass , for example , will conduct electricity . ? a charged particle made from an atom by the loss or gain of electrons . Metal atoms more easily electrons than gain them . So , they become ions . In doing so , they achieve a more electron arrangement , usually that of the nearest noble gas .
