1. what is an atom?

1. what are the parts of an atom?

1. molecules is ____________.

1. give one example of an element.

1. what is a compound?

Explanation:

1. An atom is the basic unit of matter, consisting of a nucleus (protons, neutrons) and electrons orbiting the nucleus. It is the smallest particle of an element that retains the chemical properties of that element.
2. The parts of an atom are protons (positively charged, in the nucleus), neutrons (neutral, in the nucleus), and electrons (negatively charged, orbiting the nucleus).
3. Molecules are groups of two or more atoms held together by chemical bonds. They can be made of the same type of atom (e.g., \(O_2\)) or different types (e.g., \(H_2O\)).
4. An example of an element is hydrogen (H), oxygen (O), carbon (C), or gold (Au), etc. For instance, hydrogen is an element with atoms that have one proton and one electron.
5. A compound is a substance made up of two or more different elements chemically combined in a fixed ratio. For example, water (\(H_2O\)) is a compound made from hydrogen and oxygen atoms.

3. Molecules are groups of two or more atoms bonded together (can be same or different atoms).
4. Example of an element: Hydrogen (H) (or Oxygen (O), Carbon (C), etc.).
5. A compound is a substance with two or more different elements chemically combined in a fixed ratio (e.g., \(H_2O\) from H and O).
