Which description best matches democritus's idea of the atom?
a particle that cannot be divided or destroyed
Matter that is indivisible cannot be?
The law of conservation of mass states that mass cannot be created or destroyed. This is not strictly correct, as mass and energy can be inter-converted, as in nuclear reactions. Thus, 'mass and energy cannot be created or destroyed' is more accurate.
What is a pure substance that cannot be broken into a simpler substance?
Not: atoms The answer is an element
What you mean by atom?
An atom is the basic unit of matter, consisting of a nucleus composed of protons and neutrons, surrounded by electrons in orbitals. It is the smallest particle of an element that retains the chemical properties of that element. Atoms combine to form molecules and compounds and are the building blocks of everything in the universe.
Can carbon atoms be changed from one form to another but neither created nor destroyed Is there a name for this law?
Carbon is an element. It cannot be change nor destroy. Only compound and mixture can be change.
Why can't charge be created or destroyed?
Just as the laws of conservation of matter, mass, and energy state that matter, mass, and energy cannot be created nor destroyed (in the long-term), so too do we say that particle characteristics (which derive from matter/mass/energy) such as charge cannot be created nor destroyed.
Energy may change from one form to another but it cannot be created or destroyed under ordinary conditions?
It cannot be created or destroyed under anyconditions.It cannot be created or destroyed under anyconditions.It cannot be created or destroyed under anyconditions.It cannot be created or destroyed under any conditions.

Which particle does not change in amount in an atom?

How and where material are destroyed and created?
Matter cannot be created or destroyed - it can merely be rearranged or converted to/from energy.
What are three things energy cannot do?

What does it mean that energy is neither created nor destroyed?
