Why do atoms always react in simple whole number ratios by moles? What does this mean?

Ahigh energy (high speed) particle (alpha or beta or neutron) are shot at the target;

They both go downwards and the can break apart rocks 

Those are different gas lawshere is a brief description of themcharles's law states that volume and temperature are directly proportional to each other as long as pressure is held constant.  boyle's law asserts that pressure and volume are inversely proportional to each other at fixed temperature.gay-lussac's law introduces a direct proportionality between temperature and pressure as long as it is at a constant volume.    source:
