element
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.
No, aluminum cannot be decomposed into simpler substances. It is an element with the atomic number 13 and cannot be broken down into simpler materials by ordinary chemical reactions.
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'.
Mercury is an element with the atomic number 80, which means it consists of only one type of atom: mercury atoms. Elements are the simplest form of matter and cannot be broken down into simpler substances through chemical reactions. Therefore, mercury cannot be decomposed into simpler substances because it is already in its simplest form.
An element is a substance that cannot be broken down into simpler substances with all the characteristics of that element. Elements are composed of only one type of atom and they cannot be chemically decomposed into simpler substances.
Elements like gold, silver, and platinum are examples of matter that cannot be converted into simpler substances through ordinary chemical reactions. They consist of only one type of atom and cannot be broken down into simpler components by chemical means.
Carbon is classified as an element because it consists of only one type of atom, which cannot be decomposed into simpler substances using chemical methods.
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.
Atom of carbon?
The periodic table itself cannot be broken down into simpler substances because it is a tabular arrangement of all the known chemical elements. Each element on the periodic table is a fundamental substance that cannot be further broken down into simpler substances by ordinary chemical processes.
One substance that typically does not undergo a chemical change is an element in its stable form. This is because elements are made up of one type of atom, and the chemical properties of an element remain constant. Examples include gold (Au) and oxygen (O2).
Elements and compounds (pure substances) cannot be broken down by physical changes.
Those substances are called elements. Elements are pure substances made up of only one type of atom and cannot be further broken down or decomposed into simpler substances by chemical reactions.
