A city destroyed by an atom bomb.
Hiroshima and Nagasaki
The Japanese cities Hiroshima and Nagasaki were destroyed by atom bombs at the end of WW2
What remains constant is the total of all types of energy.
I'm not sure but it is either an atom, a molecule, a neutron, or a proton.
Hiroshima was nearly totally destroyed by the atom bomb.
Atoms can be split to create nuclear energy, but can not be destroyed using the technology we currently posses and possibly not ever.
Atoms are never created or destroyed in a chemical reaction. There are the same number of each type of atom both before and after a chemical reaction. Atoms are never created of destroyed; the molecules are just re-arranged in their bonding with each other.
Atoms can be disassembled or broken apart, but in a chemical reaction nothing is created, nor destroyed. So, yes, in theory, you could take apart an atom...if you had the money for all the fancy equipment. :D
When an atom is smashed, its constituent particles do not cease to exist, although depending upon the energies involved, they may be changed into different particles. It is a well established law of nature that mass-energy is conserved, which is to say, it is not created or destroyed, although it can be changed into many different forms. Although matter is not destroyed, it can be converted into energy under some circumstances. Some nuclear processes to result in some of the matter in the atom being converted to energy. This is the source of the energy released by nuclear power plants, or nuclear bombs.
The law of conservation of mass states that mass cannot be created or destroyed in a chemical reaction. It can only change forms, but the total mass remains constant before and after the reaction. This principle is a fundamental concept in chemistry and is often used to balance chemical equations.
The Law of Conservation of Mass states that matter cannot be created nor destroyed. Since atoms comprise matter, any reaction must involve the same number of atoms on the reactants side and the product side.
