What causes atoms to form bonds?

Answer 1

Bonding occurs because elements are electronegative and have the desire to obtain a noble gas configuration.

Bonding occurs because elements are electronegative and have the desire to obtain a noble gas configuration. Ionic, covalent or polar covalent are the types of bonding.

Answer 2

atoms make bonds because each atom wnats to have a full valence shelll of electrons (they want eight electrons in their outermost shell). all of the elements, except for the noble gases, do not have a full octet (8 electrons in the outermost shell). thegroup one elements such as Na have one electron in their outermost shell. they want 8. it is easiest for them to give off one electron and then have 8 in their new outermost shell. one of the halogens, such as Cl, who has 7 valence shell electrons wants to gain one more to have 8. Na tranfers one electron to the Cl. Now they each have 8 outermost shell electrons and are happy. problem: since Na gave off an electron, it has a +1 charge. Since Cl accepted an electron, it has a -1 charge. as we know, opposites attract and so Na+1 and Cl-1 form an ionic bond and become NaCl, or tablesalt. other atoms bond for the same purpose: to get a full octet in their valence shells. however, for some elements who have 4 electrons in their outershells, it is too hard for them to give away 4 electrons or to accept 4 electrons to get their eight. instead, they will form a covalent bond where they SHARE the electrons. for example, carbon makes 4 bonds bc it wants 4 more electrons. examplE: the C will bond with 4 hydrogens and each hydrogen will share one electron with C. this gives C 8 valence shell electrons (4 from itself, 4 shared with the Hs). example 2: CO2, carbon dioxide: carbon shares 2 electrons with each oxygen. there are two oxygens and each shares 2 electrons, now carbon has 4 electrons (4 from itself and 4 shared with the oxygens)

Answer 3

Answer Bonding happens because two atoms are attracted to each other through their magnetic charges. Through either ionic or covalent boding, atoms can use their electric charges and valence electrons to combine. Valence may sound complex, though it refers simply to the outer ring of an atom's electrons. Ionic and covalent bondings are covered covered extensively on our site, including in one of my articles. So, put simply, valence electrons allow atoms to combine.

Answer 4

Two types of bonds - covalent and ionic. Covalent bonds occur when there is an overlap of energy levels in two atoms' outer electon shells such that the geometry and distance between atoms produces an overall more stable electronic configuration by sharing electron density than the two species that existed prior to bond formation. Ionic bonds form between oppositely charged ions due primarily to electostatic interactions when the distance between two or more atoms produces a more stable configuration than that of the free ions in solution.

Answer 5

There are several different kinds of bonds between atoms, which can in some cases either gain or lose electrons, forming an ionic bond, or in other cases can share electrons inside a molecule, forming a covalent bond, or can share electrons more broadly within a substance, forming a metallic bond. In all cases, it is various forms of electrostatic attraction, the attraction of positively charged protons for negatively charged electrons, which results in the bond.

Answer 6

Protons and Electrons and Valence Electron and Neutron.

Answer 7

Overlapping of atomic orbitals to create molecular orbitals can be interpreted as atomic bonding.
