An atom is the smallest piece of an elemental chemical, a molecule is the smallest piece of a compound chemical (composed of several elements). However due to quantum effects, neither an atom nor a molecule has the properties that we associate with that specific chemical. You need a minimum of several hundred or thousand atoms or molecules in most cases for the "bulk" chemical properties to begin to appear.

What are characteristics do all chemical changes have?
All chemical changes involve the formation of new substances with different properties. They typically involve changes in the arrangement of atoms and the breaking and forming of chemical bonds. Chemical changes are often irreversible and are accompanied by changes in energy.
When ice changes to water the link up of atoms does or does not change?
The bonds between hydrogen and oxygen atoms of individual water molecules do not change when liquid water changes to ice. This is a physical change called freezing, and does not cause any chemical changes to occur. Only chemical changes can cause changes in chemical bonds.
When rocks undergo metamorphic changes chemical reactions cause minerals to recrystallize or change form which agent provides the energy for these reactions?
Heat
What is something that can cause matter to move or change?
An external force, such as a push or pull, can cause matter to move or change. Additionally, changes in temperature, pressure, or chemical reactions can also lead to changes in matter.
Properties that can change the chemical composition of matter?
Heat: Applying heat can cause atoms to rearrange and form new chemical bonds, resulting in a change in the chemical composition of matter. Light: Certain wavelengths of light can excite electrons in atoms, leading to chemical reactions and a change in the composition of matter. Catalysts: Catalysts are substances that can speed up chemical reactions without being consumed, leading to a change in the chemical composition of matter. Acids and bases: Acids can donate protons while bases can accept them, causing chemical reactions that alter the composition of matter.

Why can light cause materials to change?
Light can cause materials to change because it carries energy that can interact with the atoms and molecules in the material, leading to chemical reactions or physical changes in its structure.

The bonds between hydrogen and oxygen atoms of individual water molecules do not change when liquid water changes to ice. This is a physical change called freezing, and does not cause any chemical changes to occur. Only chemical changes can cause changes in chemical bonds.
Which is the only subatomic particle that is directly involved in the chemical reactions between atoms?
An electron, it plays a part in forming/breaking all proper chemical bonds (there are other types of bonds but they don't really cause chemical reactions and as such are rather boring)
What effect do electrons from the magnetosphere have on atoms?
Electrons from the magnetosphere can cause atoms to become excited or ionized when they interact with them. This can lead to the emission of light, changes in chemical reactions, or damage to biological molecules. Additionally, these electrons can contribute to the creation of auroras when they collide with gases in the Earth's atmosphere.

Is it true that during chemical changes atoms are rearranged and different kind of matter form?
Yes, in chemical reactions the fundamental structure of the molecules (i.e., the arrangement of the atoms) changes. This differs from a physical reaction, in that in a physical reaction, only superficial traits of the substance change. A good rule of thumb for determining whether something is a physical or chemical reaction is that physical reactions are easily reversible (e.g., freezing/melting water), while a chemical reaction is not really reversible (e.g., cooking/uncooking a steak).
How do energy changes affect matter?
Assuming you mean changes of state i.e. solid to liquid, then if energy is supplied to matter then the particles or atoms move faster as they gain kinetic energy. This causes the bonds between the atoms to break, allowing the particles to flow over each other, as in a liquid. Like matter, energy is never created or destroyed in chemical reactions. Or: Every chemical change in matter includes a change in energy.
Can a chemical bond be broken?
Yes, a chemical bond can be broken through processes such as chemical reactions, radiation, or thermal energy. When a bond is broken, the atoms or molecules involved may form new bonds with other atoms or molecules.
What do most atoms undergo combining in ways that cause their atoms to become more?
Atoms combine in chemical reactions to form new compounds, which can have different properties than the individual atoms. By bonding with other atoms, atoms can achieve a more stable electron configuration, often by filling their outer electron shell to reach a state of lower energy. The resulting compounds can have enhanced stability and reactivity compared to the individual atoms.
What is the ability to cause changes in matter?
