write five difference between atom and molecules
Answers
Answer:
Explanation:
1-Atom is defined as the smallest unit of an element which may or may not exists independently. On the other hand, molecule implies the set of atoms held together by the bond, indicating the smallest unit of a compound.
2-Atoms may or may not exist in the free state, but molecules exist in the free state.
3-Atoms comprise of the nucleus (which contains protons and neutrons) and electrons. Conversely, a molecule comprises of two or more, identical or different atoms, combined chemically.
4-The shape of an atom is spherical whereas the molecules can be linear, angular or rectangular in shape.
5-Atoms are highly reactive, i.e. they participate in the chemical reaction without additional decomposition into subatomic units. However, this is not applicable to noble gas atoms. On the contrary, molecules are less reactive, as they do not take part in the chemical reaction.
6-Atoms possess nuclear bond, as it entails electrostatic attraction between the nucleus and electron. In contrast, there exist a chemical bond between atoms of a molecule, such that it encompasses single, double or triple bonds.
Answer:
Atom
1 it is the smallest particle if of an element.
2 it consist of electrons, protons and neutrons.
3 it cannot be seen with our naked eyes and cannot be seen with microscope.
4 it cannot be divided.
5 it may or may not have independent exsistance.
Molecules
1it is a group of two or more atoms combined together.
2 it consist of combination of two or more same or different atom chemical bound together.
3 it is not visible with our naked eyes but it can be seen with microscope.
4 it can be further divided to give individual atoms.
5 they are capable of having independent exsistance.
