Atoms are the small building blocks of all existing substances. They are so tiny that we can’t even observe with our naked eye. Normally atoms are in the Angstrom range. Atom is made up of a nucleus, which has protons and neutrons. Other than neutrons and protons there are other small ...
Thekey differencebetween molecule and atom is thatmolecule is a combination of two or more atoms viachemical bondingwhereas atom is an individual chemical species that can combine with each other to form molecules andions. All matter in the world is made up of atoms and molecules hence we can...
An atom is the smallest unit of an element retaining its properties, while a molecule consists of two or more atoms bonded together.
Then, mass of helium molecule is 6.6x10-26kg The Attempt at a Solution Question: Is rms speed of a helium molecule the same as the rms speed of an atom. Yes, because the atoms make up the molecule? No, helium is diatomic (right?) and so that has to be taken into a...
To live in or share a prison cell. Atom An ultimate indivisible particle of matter. Cell A single-room dwelling for a hermit. Atom The smallest particle of matter that can enter into combination; one of the elementary constituents of a molecule. Cell A small monastery or nunnery dependent on...
解析 A compound is a substance form two or more elements chemically united in fixed proportions. A molecule is a group of atom that can take part in a chemical reaction.结果一 题目 what's the difference between a compound and a molecule?rt 答案 A compound is a substance form two or ...
in the same type or different type it forms a molecule for example H2O is a molecule. Molecules are invisible to the naked eye and therefore scientists’ break them down into their atomic parts. For example, water contains two hydrogen atoms and one oxygen atom and therefore the chemical ...
