Statements are inconsistent with Dalton's atomic theory?
1)One problem with his atomic theory was that it claimed that all matter is composed of tiny indivisible atoms. We now know that atoms are divisible and are composed of smaller, subatomic particles (electrons, protons, and neutrons). 2)He also stated that atoms of an element are identical in mass- this is incorrect because all elements have isotopes (atoms with this same proton number but different numbers of neutrons) which means that atoms of an element do not have to have the same mass.
Is the statement An atom consists of a dense nucleus surrounded by a cloud of electrons best described as a law or hypothesis or a theory?
The statement "An atom consists of a dense nucleus surrounded by a cloud of electrons" is best described as a theory in the field of atomic structure. The atomic theory explains the structure of atoms based on experimental evidence and scientific principles.
Which of the following statements is NOT a part of John Dalton's atomic theory?
"Atoms are indivisible and cannot be created or destroyed" is NOT a part of John Dalton's atomic theory. This statement is actually a misconception; atoms can be further divided into subatomic particles like protons, neutrons, and electrons. Dalton's theory focused on elements consisting of indivisible atoms.
What statement did john Dalton make about atoms?
John Dalton proposed that all matter is made up of tiny, indivisible particles called atoms, which combine in simple whole number ratios to form compounds. This laid the foundation for the development of atomic theory in chemistry.
What theory describes the way atoms are arranged within a molecule?
The theory that describes the way atoms are arranged within a molecule is called valence bond theory. This theory explains how covalent bonds are formed by the sharing of electron pairs between atoms and how the arrangement of atoms in a molecule is determined by the overlap of atomic orbitals.
Why is the word atom a approperiate term for democrituss idea?
Because it was invented in 1918

What statement from daltons theory no longer true?
One statement from Dalton's atomic theory that is no longer considered true is that atoms of a given element are identical in mass and properties. We now know that atoms of the same element can have different masses due to the existence of isotopes, which are atoms with the same number of protons but different numbers of neutrons. Additionally, advancements in quantum mechanics and the understanding of atomic structure have revealed that atomic properties can vary significantly, challenging the idea of uniformity among atoms of the same element.
What is a conflict statement?
A statement which has an opposite opinion to a theory
What statement supports one of Dalton's contributions to the atomic theory?
the element carbon is made up of carbon and nitrogen

What theory is that all matter is composed of atoms?
Dalton's Atomic Theory
What is the kinetic-theory?
The theory that states that all atoms are constantly moving
Who said atoms of the same element are exactly a like?
The statement that atoms of the same element are exactly alike is attributed to John Dalton, who proposed the atomic theory in the early 19th century. Dalton's theory posited that all atoms of a given element are identical in mass and properties, which laid the foundation for modern chemistry. However, it is important to note that later discoveries, such as isotopes, revealed that atoms of the same element can differ in mass due to variations in the number of neutrons.
