What is the first theory to relate chemical changes to events at the atomic level?
The first theory to relate chemical changes to events at the atomic level was proposed by John Dalton in the early 19th century. Known as Dalton's atomic theory, it stated that elements are composed of indivisible particles called atoms, and chemical reactions involve the rearrangement of these atoms to form new substances.
Who proposed the first modern atomic theory?
The first modern atomic theory was proposed by John Dalton in the early 19th century. Dalton's theory stated that all matter is made up of tiny, indivisible particles called atoms, and that atoms of different elements have different masses and properties.
How is a molecular orbital formed?
In molecular orbital theory, MO theory, molecular orbitals are "built" from atomic orbitals. A common approach is to take a linear combination of atomic orbitals (LCAO), specifically symmetry adapted linear combinations (SALC) using group theory. The formation of a bond is essentially down to the overlap of the orbitals, the orbitals being of similar energy and the atomic orbital wave functions having the correct symmetry.
According to MO theory overlap of two p atomic orbitals produces?
According to MO theory, overlap of two p atomic orbitals produces two molecular orbitals: one bonding (π bonding) and one antibonding (π antibonding) molecular orbital. These molecular orbitals are formed by constructive and destructive interference of the p atomic orbitals.
Whose ideas led to the atomic theory of matter?
The atomic theory of matter can be attributed to the ideas proposed by the ancient Greek philosopher Democritus. He hypothesized that all matter is composed of indivisible and indestructible particles called atoms, which differ in shape, size, and arrangement. Democritus' atomic theory laid the foundation for modern atomic theory.

What was Moseley's atomic theory?
Moseley was the first to clear and scientifically justify in 1913 the atomic number studying X-ray spectra of chemical elements. But Moseley hadn't a personal atomic theory, he was not the discoverer of the atomic theory.
