Nothing happens, all stay the same.
Nope. All that happens in chemical reactions is that atoms are rearranged into new molecules or compounds. You can't destroy atoms in a chemical reaction so whatever you begin with is what you end up with.
This statement is not accurate. Atoms of the same element are identical, while molecules can be made up of different combinations of atoms. Each element has its own unique type of atom with specific properties, while molecules are formed by bonding different atoms together.
Covalent bonding can occur in solids, such as in diamond where each carbon atom forms covalent bonds with four other carbon atoms. However, in some solids, like metals and ionic compounds, the bonding is mainly metallic or ionic, respectively, due to the different types of interactions between atoms.
Covalent bonding joins hydrogen atoms by sharing electrons.
The very heart of bonding is the attraction of positive and negative charges. There are three standard types of bonding among metallic and nonmetallicÊatoms. Non metallic atoms that can bond to other non metallic atoms is called covalent bonding. Non metallic atoms that can bond to metallic atoms is called ionic bonding. And lastly, metallic atoms that can bond to other metallic atoms is called metallic bonding.
If atoms were bigger, the fundamental properties of matter would change dramatically. Increased atomic size would likely lead to weaker electromagnetic forces between atoms, resulting in lower cohesion and altering the structure of molecules. This could affect the stability of compounds and materials, potentially making them less dense and changing their physical states. Additionally, larger atoms might disrupt chemical bonding and reaction rates, leading to a vastly different chemistry and, consequently, a different biological and physical world.

I am quite sure that rust is a chemical change. Rust is caused when oxygen atoms begin bonding with the iron in the nail, which makes it a compound instead of a pure element.

In an ionic bond atoms are attracted by electrostatic forces.
A physical change is a change where the atoms might get separated but there is no change in it's chemical. It all depends on what you did with the atoms (For example, poisoning something is a physical change), and if the thing itself is edible.
Change of state is always physical. You have not lost or gained any atoms. Therefore its physical.
In a chemical change, the particles that change are atoms and molecules. Bonds between atoms break and form new connections, leading to the formation of different substances with unique chemical properties. The number and type of atoms remain the same before and after the reaction, but their arrangement and bonding change.
Cracking an egg and stirring it are physical changes because the molecular composition of the egg remains the same. A chemical change would involve a new substance forming, which is not the case when you crack and stir an egg.
