oxygen gas (O₂) is a molecule composed of two oxygen atoms bonded together, while water (H₂O) is a molecule made up of two hydrogen atoms and one oxygen atom. Compounds such as carbon dioxide (CO₂) and sodium chloride
An atom can be an ion, but not all ions are atoms. These are the important differences between an atom and an ion.
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 ...
A monoatomic molecule is 1 that includes only 1 element's atom. E.g., Na,He and so on. A diatomic molecule is 1 that has 2 atoms in an element's molecule. E.g., O2 as well as N2. A polyatomic molecule is 1 that has more than 2 atoms in an element's molecule. E.g., ...
In the case of helium, which is a diatomic molecule, the rms speed would be slightly different from that of a single helium atom due to the presence of the two atoms and their interactions. Therefore, it is important to consider the specific properties of the substance when cal...
What is the difference between an atom, a cell, and a molecule? If the solute concentration is greater outside the cell, where is the water concentration greater? Which direction would the water move? What are the major ions that contribute to membrane potential and how ar...

, the three oxygen atoms that compose that molecule are bonded in a unique way. Two of the oxygen atoms are bonded by a double covalent bond (two pairs of electrons being shared), and one of those oxygen atoms is simultaneously sharing a coordinate covalent bond with a third oxygen atom....
binding energy- the energy required to separate particles from a molecule or atom or nucleus; equals the mass defect separation energy energy,free energy- (physics) a thermodynamic quantity equivalent to the capacity of a physical system to do work; the units of energy are joules or ergs; "en...
hydrogen and oxygen. One molecule of water is always made up of two hydrogen atoms and one oxygen atom. This is why water is referred to as H₂O in science. Water is created when elements chemically combine. That is, hydrogen and oxygen form achemical bondwith each other to form water...
