atom
The smallest part of an element that cannot be divided by chemical means is an atom. Atoms are made up of protons, neutrons, and electrons, and they retain the unique chemical properties of the element they represent.
an element --- considered a pure substance
An atom is the smallest bit of matter. Atom is from the Greek, and means cannot be cut.The 'tom' bit means cut or divide, and is the root word behind tome (part of a volume), micro-tome (a cutting machine), tomography ( a means of visualizing slices of tissue). But only maybe for tomahawk.
According to the Law of Conservation Of Mass,Matter is neither created nor destroyed.It means a chemical equation show that matter is always conserved in a chemical reaction.It is shown as number of atoms both sides of the reaction before and after remains the same.
The literal meaning of a molecule is a group of two or more atoms held together by chemical bonds. It is the smallest unit of a chemical compound that retains the chemical properties of that compound.
An atom.
Atoms are the smallest particles of matter. An atom can not be divided by normal chemical means, they can only be divided during nuclear fusion.
The smallest part of an element that cannot be divided by chemical means is an atom. Atoms are made up of protons, neutrons, and electrons, and they retain the unique chemical properties of the element they represent.
Only physical means; chemical means alters the chemical composition.
yes
an element --- considered a pure substance
retains the chemical identity of that element.
Atoms: smallest unit of an element. Molecule: smallest unit of a compound., combination of atoms of the same or different elements., a group of atoms chemically bonded together. Both: divisible by chemical or nuclear means, smallest unit that can be isolated through physical changes.
The smallest component of an element having the chemical properties of the elementatom comes from the word atomos ( a= not/ tomos= devisible)it was called this because it was belived that all matter was made from individual descrete particles so not visible.MIT lecture on the origin of the atom,A direct answer for this..The word 'atom' means 'uncuttable' or 'smallest indivisible particle of matter
ATOM
Matter is a pure substance if it can only be separated by chemical means, NOT physical means. This could be a compound or an element. The opposite is a mixture which can be separated/broken into smaller parts by physical means.
