atom, element, compound, molecules. with examples
Answers
Answer:
Atom-An atom is a particle of matter that uniquely defines achemical element. An atom consists of a central nucleus that is usually surrounded by one or more electrons. Each electron is negatively charged. The nucleus is positively charged, and contains one or more relatively heavy particles known as protons and neutrons.
Element-An element is a substance that is made entirely from one type of atom. For example, the element hydrogen is made from atoms containing a single proton and a single electron. ... If you change the number of neutrons an atom has, you make an isotope of that element.
Compound-A compound is a material composed of two or more components. Water, carbon dioxide and table salt are some examples of compounds.
Molecules-A molecule is the smallest particle in a chemical element or compound that has the chemical properties of that element or compound. ... Examples of such elements are oxygen and chlorine. The atoms of some elements do not easily bond with other atoms. Examples are neon and argon.

ᴀᴛᴏᴍ ::
Many atoms consist of a positively charged nucleus consisting of protons and neutrons surrounded by a cloud of electrons charged negatively. An atom is any particle of matter at its most basic level which contains at least one proton. Here are some
ᴇxᴀᴍᴘʟᴇs ᴏғ ᴀᴛᴏᴍ ::
hydrogen (H) neon (Ne).
ᴇʟᴇᴍᴇɴᴛ ::
An element is a substance whose atoms all have the same number of protons: another way of saying this is that all of a particular element's atoms have the same atomic number.
