An atom is the smallest part of an element that still has all of its properties, while a molecule is a group of atoms bonded together.
An atom is the smallest particle of an element that has the properties of that element. A molecule is composed of two or more atoms covalently bonded. The atoms can be the same element, like hydrogen gas, H2, or the atoms can be different elements, like carbon dioxide, CO2, which is not only a molecule, but is also a compound because it contains at least two different elements.
An atom is the smallest complete particle of an element. A molecule consists of two or more atoms joined together.
they both are small
The 3' end of a nucleotide sequence refers to the end where the sugar molecule has a free hydroxyl group attached to the 3rd carbon atom, while the 5' end refers to the end where the sugar molecule has a phosphate group attached to the 5th carbon atom. These differences in chemical structure affect how nucleotides are linked together in a DNA or RNA molecule.
A hydrogen bond.
A water molecule is polar because there is an uneven distribution electrons between the oxygen and hydrogen atoms. The negative pole is near the oxygen atom and the positive pole is between the hydrogen ofatoms.
A bond that forms between a positively charged hydrogen atom of one molecule and a negatively charged region of another molecule is a hydrogen bond. Hydrogen bonds are weak attractions between a slightly positive hydrogen atom and a slightly negative atom (like oxygen or nitrogen) in another molecule.
A sulfur molecule contain more atoms.
A sulfur molecule contain more atoms.
A hydrogen bond is formed between the proton (H+) and the ammonia molecule (NH3). In a hydrogen bond, the hydrogen atom of one molecule is attracted to the electronegative atom of another molecule.
They both have at least one sulphur atom
In organic chemistry, elimination reactions involve the removal of atoms or groups from a molecule to form a double bond or a new functional group. Substitution reactions, on the other hand, involve the replacement of an atom or group in a molecule with another atom or group.
