Каква е разликата между йонните и ковалентните връзки?

Въпрос

Въпреки че съществуват различни видове химични връзки, our focus in this article is to discuss the difference between Ionic и Covalent облигации. The most basic types of chemical bonds can be said to be either ionic or covalent bond.

Chemical compounds are fashioned by the connection of two or or more atoms. A stable compound happens once the overall energy of the mix has lower energy than the separated atoms. The sure state implies a web attraction between the atoms.

Chemical bonds Atoms tend to rearrange themselves within the most stable patterns doable, which suggests that they need an inclination to finish or fill their outermost lepton orbits.

They be a part of with alternative atoms to try to to simply that. The force that holds atoms along in collections called molecules is stated as a bond.

Има 2 main types and a few types of secondary chemical bonds – (Ionic and Covalent Bonds)

Ionic bonding involves a transfer of associate degree lepton, thus one atom gains associate degree lepton whereas one atom loses associate degree lepton.

One in every of the ensuing ions carries an electric charge (anion), and therefore the alternative particle carries a electric charge (cation). The result of opposite charges attracting, is that the atoms bond along to make a molecule.

The most common bond in organic molecules – а ковалентна връзка involves the sharing of electrons between 2 атоми. The try of shared electrons forms a replacement orbit that extends round the nuclei of each atoms, manufacturing a molecule.

Има 2 (two) secondary styles of valence bonds that are relevant to biology — polar bonds and H bonds. Chemical compounds are fashioned by the connection of 2 or a lot of atoms. A stable compound happens once the overall energy of the mix has lower energy than the separated atoms.

The sure state implies a web attraction between the atoms (a chemical bond) Atoms tend to rearrange themselves within the most stable patterns doable, which suggests that they need an inclination to finish or fill their outermost lepton orbits.

Ionic Bonds

Covalent Bonds

Описание Bond between metal and nonmetal. The nonmetal attracts the electron, so it’s like the metal donates its electron to it. Bond between two nonmetals with similar electronegativities. Atoms share electrons in their outer orbitals.

Melting Point High Low
Boiling Point High Low
State at room temperature Solid Liquid or Gas
Примери Sodium chloride (NaCl), Sulfuric Acid2ТАКА4 ) Methane (CH4), Hydrochloric acid (НС1)
Chemical Species Metal and nometal (remember hydrogen can act either way) Two nonmetals
