Bohr's theory helped explain why?

Bohr's theory helped explain why electrons orbit the nucleus in specific energy levels, rather than spiraling inward towards the nucleus due to electromagnetic forces. This theory also provided a framework for understanding the discrete emission and absorption of energy by atoms in the form of photons.


What is the theory used to explain how atoms join together?

The theory used to explain how atoms join together is called chemical bonding. Chemical bonding involves the sharing or transferring of electrons between atoms to form molecules or compounds. There are different types of chemical bonds, including covalent bonds, ionic bonds, and metallic bonds.

How does the particle theory of matter explain what happens when substances are combined?

The particle theory of matter posits that all matter is composed of tiny, constantly moving particles. When substances are combined, their particles interact, possibly leading to new arrangements or reactions depending on the nature of the substances. For example, in a physical mixture, the particles retain their individual properties, while in a chemical reaction, the particles may bond and form new substances. This theory helps explain changes in properties, such as color or temperature, that occur during these interactions.
