A particle is defined as a small potion of matter. From its definition, then a single atom can be considered as an atom. This is because an atom is the smallest unit of matter. Also, a molecule can be considered as a particles since it is a small portion of a certain object.

Answer from: krishawnnn

A particle can be a single atom and can also be a molecule.

Further Explanation Matter Matter is anything that has weight and occupies space. Matter exists in three states, liquid, gases and solids. Matter is made up of small particles that are in continuous random movement. Particles A particle refers to a single atom or a group of atoms that are bonded together and functions as a single unit. Therefore, matter is made up of particles which can either be single atoms or chemically bonded atoms to make a molecule. Hence, a molecule is also a particle of matter. An atom An atom is the smallest particle of an element that can take part in a chemical reaction. Atoms are made up of sub-atomic particles which include; protons, neutrons and electrons. When two or more atoms are bonded together they form a molecule. Molecule A molecule is the smallest particle of an element or a compound that has similar properties of that particular compound or element. Molecules could be made up of atoms that are similar such as oxygen molecule or atoms that different from different elements, such as water molecule. The bonding of atoms to form molecules occurs as a result of sharing or transfer of electrons between atoms.

Answer from: Quest

2h2o2--> 2h2o + o2

this reaction is of the spontaneous decomposition of hydrogen peroxide down into water and oxygen.

add 2 molecules of hydrogen peroxide and 2 molecules of water. since oxygen is naturally diatomic, the total number of atoms of each element is now the same on both sides of the equation so it is balanced.

this may not be entirely correct but let me know.

Answer from: Quest

they are all solids.
