Atomic Theory is
A. subject to change if new information is discovered***
B. a solution to the problem of differing isotopes.
C. unchangeable
D. a descriptive table that list all of the elements.
looks good to me.
The correct answer is A. Atomic Theory is subject to change if new information is discovered.
Atomic Theory is a scientific theory that describes the nature of matter at the atomic level. It was first proposed by John Dalton in the early 19th century, and since then, it has been revised and expanded upon by many scientists.
The theory suggests that all matter is composed of indivisible particles called atoms, which cannot be created or destroyed. Atoms of different elements have different properties, such as mass and chemical behavior. Atoms combine in specific ratios to form compounds, and chemical reactions involve rearrangements of atoms.
However, Atomic Theory is not a fixed or unchangeable concept. As new scientific discoveries are made and more information is obtained through experimental evidence, our understanding and description of atoms and their properties can change. The theory is constantly being refined and updated to incorporate new findings and better explain the behavior of atoms.
Therefore, Option A is the correct answer because Atomic Theory is indeed subject to change if new information is discovered.
