A nail is typically made of iron, which has an atomic number of 26. The atomic weight of iron is approximately 56 grams per mole. Given that the average weight of a nail is around 5 grams, we can calculate that there are roughly 6.022 x 10^23 iron atoms in a nail based on Avogadro's number and the molar mass of iron.
A single atom cannot be divided further; it is the smallest unit of matter.
When a nail rusts, it undergoes a chemical reaction with oxygen in the air to form iron oxide (rust). This process adds additional mass to the nail in the form of the iron oxide. Therefore, the mass of the rusted nail is greater than the mass of the nail before it rusted.
The iron is reacting with other substances in the surrounding enviornment. This typically changes the iron atoms into molecules of iron oxide. Because the rust contains more atoms, the iron and now oxygen atoms, the mass of the nail increases.
Iron nail contains metallic bonding, which is different from ionic or covalent bonding. In metallic bonding, electrons are shared among all the metal atoms, creating a "sea of electrons" that hold the metal atoms together.
The iron is a more active metal than copper, so the iron atoms in the nail replace the copper atoms in the copper sulphate solution, so it becomes iron sulfate. The copper atoms will start to build on the iron nail, as well.

It is not possible to determine the number of molecules in 3 grams of nail without knowing the chemical composition of the nail. The number of molecules present would depend on the elements and compounds that make up the nail.
A single atom cannot be divided further; it is the smallest unit of matter.
Bonds are formed between some of the iron atoms in the nail and oxygen atoms from the air.
When heat is applied to an iron nail, the thermal energy causes the iron atoms to vibrate more rapidly, increasing their kinetic energy. As a result, the iron nail will expand due to the increased movement of the atoms. This expansion is a result of the increase in temperature causing the atoms to move further apart, leading to a temporary increase in the length of the nail.

When an iron nail is placed in mercury, a reaction called amalgamation occurs. The iron atoms from the nail react with the mercury atoms, forming an alloy called an amalgam. The iron nail gets coated with a layer of amalgam, which can make the nail appear silver-like and can change its properties.
The chemical symbol of an element doesn't depend on the number of atoms.
No, a nail does not become lighter when it rusts. Rust is actually iron oxide that forms on the surface of the nail, which can increase the overall weight of the nail due to the addition of oxygen atoms from the rusting process.
The iron is a more active metal than copper, so the iron atoms in the nail replace the copper atoms in the copper sulphate solution, so it becomes iron sulfate. The copper atoms will start to build on the iron nail, as well.
