When an atom loses one or more electrons to form a positive ion the energy is?

When an atom loses one or more electrons to form a positive ion, the energy required is known as ionization energy. This is the energy needed to remove an electron from the atom.


When absorbed light energy is released by matter it is called what?

Example for light energy is absorbed or released, Heat is released and absorbed, electrical energy absorbed or released...


What form of energy is released or absorbed in most chemical reactions?

Heat energy.


Can a chemical reaction take place when energy is neither released nor absorbed?

Energy is either released or absorbed in form of heat or light. Energy participates in all reactions.


When 2 atoms combine to form a molecule energy is always absorbed always released never absorbed or released sometimes absorbed and sometimes released?

When 2 atoms combine to form a molecule, energy can be either absorbed or released, depending on the specific atoms involved and the type of bond being formed. This process can result in either an exothermic reaction (energy is released) or an endothermic reaction (energy is absorbed).


What determines whether energy will be released or absorbed during a chemical reaction?

The difference in energy between the products and reactants of a chemical reaction determines if energy will be released or absorbed. If the products have lower energy than the reactants, energy will be released in the form of heat or light. If the products have higher energy, then energy will be absorbed.


As two chlorine atoms combine to form a molecule energy is released absorbed created or destroyed?

Energy is released when two chlorine atoms combine to form a molecule. This is because the bond formation is exothermic, meaning it releases energy in the form of heat.


What can be absorbed and released as the result of a chemical reaction?

In a chemical reaction, energy can be both absorbed and released. When energy is absorbed, it is required to break bonds in the reactants, and when it is released, it is due to the formation of new bonds in the products. Additionally, atoms and molecules can also be absorbed and released in various forms during a chemical reaction.


What is the most common form of energy released or absorbed when matter changes?

It's thermal energy my dear.


How energy is made available by chemical reaction?

in chemical reactions, energy is absorbed or released when chemical bonds are broken and new ones are formed.


Is more energy absorbed than released is the result of an endothermic chemical reaction?

In an endothermic reaction, heat is taken in from the environment. Heat is a form of energy. Therefore, energy is taken in, i.e. absorbed.


What happens to energy when a solution forms?

When ions are formed energy of the ionised compound's energy increases. But it nay vary with conditions.
