An element.
Just 3, as in the question. You cannot get simpler that that!
This is true not just in geometry but in every field of knowledge. You can define complicated concepts in terms of simpler ones, and those simpler ones in still simpler ones and so on. However, you will end up with a few terms which cannot be defined in terms of simpler concepts (without going into a circular definition). These terms must remain undefined.
It is so much simpler and quicker to use your calculator, but since you cannot be bothered to do so, the answer is 618.
because a substance cannot be decomposed into simplier substances by chemical or physical means
Element Compounds can be broken down to elements (atoms) which cannot be decomposed further into simpler substances (that's why they're called a-toms, from Greek 'à-tomos', meaning 'un-sliceable'.
If you are not concerned about atoms, electrons, neutrons, protons and other sub atomic particles, but confine to chemical substances occurring in nature or man made, the substance that cannot be broken into simpler substances is an "element" (usually enumerated in a periodic table).A chemical element cannot be decomposed into a simpler substance.Elements. They are defined as substances in their simplest form and cannot be broken down or decomposed into any simpler substances. They include all elements in the periodic table of elements.
An element
Atom of carbon?
Elements and compounds (pure substances) cannot be broken down by physical changes.
An element cannot be separated into simpler substances by chemical means.
Chemical property, it cannot be decomposed by ordinary chemical change.
An element
compounds CAN be decomposed elements CANTThe answer would be Mercury because it is an element and can't be broken down by chemical means. but methane, ethanol and ammonia can be broken down by physical means because they are compounds.
Elements cannot be changed into simpler substances by chemical means. To change them into simpler particles, you need nuclear means.
