Democritus's ideas were not helpful in explaining chemical behavior because they lacked experimental support.
The formula H2O represents a water molecule, composed of two hydrogen atoms bonded to one oxygen atom. It is the chemical formula for water, which is essential for life and has unique properties such as high polarity and surface tension.
Bohr hypothesized that electrons orbit the nucleus of an atom in specific energy levels or shells, and that they can jump between these levels by absorbing or emitting energy. This led to the development of the Bohr model of the atom, which provided a more accurate description than previous models.
An atom is organized with a nucleus at its center, containing protons and neutrons. Electrons orbit the nucleus in specific energy levels or shells. The nucleus is positively charged, while electrons are negatively charged, creating a stable, neutral atom.
A chemical bond is the force that holds atoms together in a molecule, resulting from the attraction between the positively charged nucleus of one atom and the negatively charged electron cloud of another atom.
In an ionic bond, electrons are transferred from a metal atom (which loses electrons to become a positively charged cation) to a non-metal atom (which gains electrons to become a negatively charged anion). This transfer of electrons creates an electrostatic attraction between the oppositely charged ions, resulting in the formation of an ionic compound.
Dmocritus supposed that the smallest part of matter is an indestructible atom.
Because it was invented in 1918
Bohr's description of an atom: an atomic nucleus positive surrounded by nedative electrons placed on predetermined orbits.
