Bond formation is possible when the resulting entity has an energy less than the sum of individual energies of the constituents. That is, when a bond forms , we can immediately say that the particular system has become stabilized. For example, consider the reaction
A + B = AB
Here, E(AB) < E(A) + E(B).
If, the bond formed is covalent, it'll mean that now A and B are sharing electrons between them (1 pair or 2 pairs, etc).
If, the bond is ionic , it'll mean that one of A or B has transfered an electron to the other and now the duo is electrostatically bound.
With respect to chemical reactions, bond formation can produce a lot of changes :
-color change due to the property of the newly formed compound
-one may observe bubbles
-heating of the beaker/test tube (in case of exothermic reactions)
-pH change, etc
If you're interested in thermodynamics , it's worthwhile to know, that during the progress of a reaction (bond dissociation or formation, etc) the Gibb's free energy is bound to decrease. In fact, the direction of reaction is decided based on G (i.e, direction in which deltaG is -ve)
And, yes if a new bond forms in a chemical reaction, ne might even end up with an explosion .. (in case of highly exothermic reactions like combustion,etc)
What else can I help you with?
What type of chemical reaction occurs when electrons are shared?
no chemical reaction takes place . when electrons are shared it is known as covalent bond
What element do in a reaction?
What do elements do in a reaction? A: The elements that are present form a chemical bond. This happens because of the fact that the elements that are present to form such combine together to make the chemical bond.
What happens when a nonmetal and a nonmetal bond?
a reaction happens
What happens between atoms during a chemical reaction?
During a chemical reaction, bonds between atoms are broken and new bonds are formed. Atoms rearrange to form new molecules or compounds, resulting in a change in the chemical properties of the substances involved in the reaction. Energy may be absorbed or released during these bond formations and breakages.
What chemical reaction makes the Shake-N-Cast harden?
The chemical reaction that makes Shake-N-Cast harden is a hydration reaction between the product and water. This reaction forms a strong bond between the material particles and creates a solid and durable structure.
What kind of reaction forms when a chemical bond breaks and a new bond forms?
Chemical duhhh
What happens when chemical bond forms?
energy is released
What happens to energy when a chemical bond is broken or forms?
When a chemical bond forms, energy is absorbed between the atoms that bond. When a chemical bond is broken, energy is immediately and dramatically released.
What type of chemical reaction occurs when electrons are shared?
no chemical reaction takes place . when electrons are shared it is known as covalent bond
What element do in a reaction?
What do elements do in a reaction? A: The elements that are present form a chemical bond. This happens because of the fact that the elements that are present to form such combine together to make the chemical bond.
What type of change had to happens for elements to form water?
A chemical reaction/bond.
What happens when 2 atoms become a molecule?
There is a chemical reaction that occurs and energy is infused into a covalent bond.
What are components of the chemical reaction?
reactants and products and bond energy creates a chemical reaction
What happens to energy and matter in a chemical reaction?
Energy and matter are both conserved during a chemical reaction, but the energy may change form, for example, from chemical potential energy to evolved heat. The matter also forms a new type of chemical bond and/or breaks an old type of chemical bond.
What happens when a nonmetal and a nonmetal bond?
a reaction happens
Which change occurs when fluorine forms an ionic bond?
The ionic bond is formed during a chemical reaction.
What happens to the potential energy of the resulting compound when a chemical bond forms?
The potential energy is transformed to heat or light energy
