The term for free electrons in metals transferring energy by colliding with other atoms or electrons is _____.
shepuryov [24]
Conduction

In metals, the electrons of each atom are delocalized, which means they are free to move about in the structure of the metal. When heat is applied at one end of the metal, the electrons there are excited and collide with surrounding particles, transferring their energy to them. This is what makes metals very good conductors of both heat and electricity.

NeTakaya

Answer:

not a reason? if you ask a reason ,i can say An actual yield is the mass of a product actually obtained from the reaction. It is usually less than the theoretical yield. The reasons for this include:

-->incomplete reactions, in which some of the reactants do not react to form the product

practical losses during the experiment

->side reactions (unwanted reactions that compete with the desired reaction)

->reversible reactions

->impurities in reactants

but you asked for not reason then it can be anything lul, like balanced chemical equation, rate of reaction and etc etc ✌️;)
