Matter and energy are fundamentally different concepts, and their weight cannot be directly compared. Matter has mass and occupies space, while energy is a property of matter and is not bound by mass in the traditional sense. According to Einstein's equation (E=mc^2), energy can be converted to mass and vice versa, which illustrates that they are interconnected rather than one being inherently heavier than the other. Thus, it is not accurate to say that matter is always a lot heavier than energy.
In terms of mass, matter is considered to be heavier than energy because matter has mass and energy does not. However, in terms of potential to cause change or do work, energy can be more powerful than matter.
No
Objects are heavier than others due to differences in their mass and density. Mass is the amount of matter in an object, while density is how compact that matter is. Objects with higher mass or higher density will be heavier than those with lower mass or lower density.
To conserve energy in beta decay.
not always but I guess it could be heavier than iron if their was a lot more of it.
Yes, charged batteries are typically heavier than uncharged batteries due to the presence of stored energy in the charged batteries.
Matter is everything that isn't energy. There is nothing other than matter and energy. You can't compare the two. It's like asking, "What's bigger than the universe?"
New elements - helium always, heavier elements often (up to iron) and heavier than that if the star explodes.
if it is an object, than it is composed of matter. if it is a form of energy, then it is not concidered matter
No. Basically, if you fuse anything heavier than iron, you will require energy input, rather than releasing energy.

It isn't. How did you get that idea? Ice is much lighter than lead, for the same volume.
