Why do atoms join in a chemical bond?

Answer 1

Atoms bond because they have an inherent need to have their outermost level of electrons be "full".

Some lose their electrons to eliminate a level of energy, at which point the new outer most level (the one underneath the one that removed) electrons do not occupy a level until the levels closes to the nucleus is are full.

At This point they are ionic. The other bonding element gains the losing atoms electrons.

This results in one atom being positively charged and the other negatively charged resulting in attraction between the two.

(cations and anions respectively)

Take Table salt: Sodium and Chloride combine to form this sodium looses a charge from it's outermost ring to be "full", while chloride gains this electron. This results in sodium being positively charged since the number of positively charged protons out numbers electrons, and chloride becoming negative because the negative electrons outweigh the number of positive protons

yoooooooooooooooooooooooooooooooooooooooooooooooooooooooooo

Answer 2

Chemical bonding is done by atoms because the bond makes the atoms more stable. The number of an atoms electrons determines how strong the force to bond is and will attract atoms that are 'weaker' then itself.

Answer 3

Based on your question, you have probably noticed that just throwing two chemicals together does not mean that a bond will form. This fact is a good thing, because if every chemical or element that came in contact with another bonded, the world would be constantly reacting. In order for chemicals to bond, a reaction needs to take place. Without adding energy, a reaction will only take place if both compounds or elements will become more stable after the reaction. "Becoming more stable" means that they will both have a full octet of electrons, and a complete energy level.

If you look at a Periodic Table, group one elements have one valence (or outer energy shell) electron. In order to be stable it wants a full octet, so it will react with a group seven element so each element in the compound has a full octet. It does this by giving its electron to the group seven element, because it is far easier to lose one electron than it is to gain seven. There is much more that goes with this process, for example compounds that have more than two elements, but you get the general idea.

Answer 4

The short answer is, the electron arrangement in any atom is at its most stable when the outer shell is full, and by various arrangements of either sharing electrons, or transferring electrons from one atom to another, atoms obtain more stable electron arrangements, which bonds them together. They are connected either by shared electrons, or because when electrons are transferred, the result is both positively and negatively charged ions which attract each other by means of electrostatic force.

Answer 5

Atoms join in a chemical bond to achieve a more stable electron configuration. By sharing or transferring electrons, atoms can fill their outer electron shells and become more energetically stable, leading to a lower overall energy state for the molecule. This stability is the driving force behind the formation of chemical bonds.

Answer 6

Atoms bond because they have an inherent need to have their outermost level of electrons be "full".

Answer 7

Most of the atoms form chemical bonds to gain stability..they gain , lose or share electrons to get stabilily.

Answer 8

Atoms bond to decrease their electronegative types.
