This depends on the position of the atom in the reactivity series . High up the series ions form with extreme easiness and don't need energy . The demand for energy increases as we go down the series . By the way , the simple series is : K Na Ca Mg Al Zn Fe Ni Pb (H) Cu Hg Ag Au Pt

Why is energy needed to form positive ions?
because can
Where does the energy needed to form positive ions come from during ionic bonding?
The energy needed to form positive ions during ionic bonding comes from the transfer of electrons between atoms. When an atom loses one or more electrons to become a positive ion, it releases energy. This energy is derived from the electrostatic attraction between the positively charged nucleus of one atom and the negatively charged electrons of another atom.
How would you compare the formation of positive ions with the formation of negative ions in terms of energy changes?
The formation of positive ions typically requires energy input in the form of ionization energy to remove electrons, whereas the formation of negative ions releases energy in the form of electron affinity when electrons are added. Positive ions have higher potential energy compared to their neutral atoms, whereas negative ions have lower potential energy. Overall, the energy changes involved in forming positive and negative ions are opposite in nature.
How are elements that form positive ions grouped in the periodic table relative to elements that form negative ions?
The lower the the Atomic Number, the higher the Ionic Energy.
Why is an outside source of energy needed for electrolysis?
An outside source of energy is needed for electrolysis to overcome the activation energy barrier and drive the non-spontaneous redox reactions that occur during the process. This energy is required to separate the ions in the electrolyte solution and facilitate the transport of charges towards the electrodes for the desired chemical reactions to take place.
Is base an endothermic or an exothermic?
Base dissociation is an endothermic process, meaning that it requires energy in the form of heat to occur. The energy is needed to break the bonds within the base molecule and allow it to dissociate into ions.
What are elements lose electrons and form positive ions named?
The elements that lose electrons and form positive ions are called metals. They will lose the electrons from their highest levels of energy to gain a more positive charge and form positive ions.
What of the following is a form of stored energy?
Batteries are a form of stored energy. They contain chemical energy that can be converted into electrical energy when needed.
The chemical energy needed for reactants to form products?
activation energy
What is the lattice energy of a compound?
The lattice energy of a compound is the energy released when gaseous ions come together to form a solid lattice structure. It is a measure of the strength of the ionic bonds within the solid. A higher lattice energy indicates stronger ionic bonding.
How is the ionization energy of an element defined?
Ionization energy is the energy needed to remove 1 mole of loosely bonded electrons from one mole of atoms or ions.
When is active transport needed?
Active transport is needed when molecules or ions need to move against their concentration gradient, from an area of low concentration to high concentration. This process requires energy in the form of ATP to pump the molecules or ions across the cell membrane. This allows cells to maintain proper concentrations of molecules and ions inside and outside the cell.
