∙ 8y ago
Atoms: smallest unit of an element.
Molecule: smallest unit of a compound., combination of atoms of the same or different elements., a group of atoms chemically bonded together. Both: divisible by chemical or nuclear means, smallest unit that can be isolated through physical changes.

What is the ratio of atoms?
A chemical formula gives the number ratio of the different kinds of atoms present in the compound. This means that the ratios are the same if you count in individual atoms, dozens of atoms, or molecules of atoms.
Is atoms are divisible or non-divisible?
Atoms are divisible They are made up of sub-atomic particles including quarks, protons, neutrons, electrons, ect.
Balanced chemical equations imply what a. Numbers of molecules are conserved b. Numbers of atoms are conserved c. Volume is conserved d. a and b or e. b and c?
jj
What is the difference between the function of the coefficient and the subscript in a balance equation?
The coefficient is a count of the number of molecules of each substance in a chemical process. The subscript is the number of atoms of an element in each molecule.
What does a n mean in a formula?
This is an unknown number of atoms or molecules.
Can molecules break apart into atoms during a chemical change?
No, being that atoms are only divisible under special spectrometry conditions in a laboratory.
Do atoms break in reactants?
No. Atoms never, ever break in chemical reactions. Molecules break if you want to see atoms break, look up nuclear reactions
How else are nuclear reactions unlike chemical reactions?
In nuclear reactions the atom itself changes while molecules and/or structural organisation of atoms do in chemical and physical changes.
When does chemical energy change into nuclear energy?
Chemical energy does not change into nuclear energy. Chemical energy is associated with the bonds between atoms in molecules, whereas nuclear energy is associated with changes in the nucleus of an atom, such as nuclear fission or fusion.
When two atoms combine to form a larger atoms its called?
Atomic fussion, which takes place inside stars and fused Hydrogen atoms together to form Helium atoms. Nuclear fusion
What do nuclear energy and chemical energy have in common?
Nuclear energy and chemical energy both involve potential energy stored within particles or bonds. However, nuclear energy involves changes in the nucleus of an atom (nuclear reactions), while chemical energy involves changes in the arrangement of atoms and electrons in molecules (chemical reactions).
Are atoms and molecules a type of chemical?
No. Atoms and molecules are what make up all chemicals.
What makes a chemical reaction different from a physical change?
In a chemical reaction, atoms are rearranged, such that some atoms get out of some molecules and join other molecules.
Molecules contain atoms that are what?
a molecuole is a chemical combination of two atoms
Is a chemical bond a force or a chemical?
Molecules are composed of two or more atoms linked together. The attractive forces that link these atoms together are called chemical bonds. The same idea is with forces , except on a larger scale. Forces link MOLECULES to MOLECULES. Bonds link ATOMS to ATOMS.
Is chemical energy a form of nuclear energy?
No, chemical energy and nuclear energy are two distinct forms of energy. Chemical energy is released during chemical reactions involving the rearrangement of atoms in a molecule, while nuclear energy is released during nuclear reactions involving changes in the atomic nucleus.
Atoms bonded together to form a chemical unit are called?
Molecules
