Ion,sorry.Borek said:You are confusing something, you can't add electron to atom to make it a cation.
A bond is a strong attraction between two atoms or molecules that holds them together in a stable arrangement. It is formed when the atoms share or exchange electrons.
Energy is the ability to do work or cause change. In the context of chemical bonds, energy is required to break existing bonds and is released when new bonds are formed.
In the formation of a bond between a Na cation (positively charged sodium ion) and another atom, energy is gained because the Na cation is able to transfer its outermost electron to the other atom, resulting in a more stable arrangement of electrons and a lower overall energy state for the system.
The energy gained during bond formation is measured in units of kilojoules per mole (kJ/mol). This is a measure of the amount of energy required to break one mole of bonds in a substance.
Yes, bonds can also form without gaining energy. This can occur when two atoms with similar electronegativities share electrons equally, resulting in a stable bond with no net gain or loss of energy.
