According to Dalton's atomic theory, one true statement is that all matter is composed of indivisible atoms, which are the fundamental building blocks of matter. Additionally, Dalton proposed that atoms of the same element are identical in mass and properties, while atoms of different elements differ in mass and properties. This theory laid the groundwork for modern chemistry by introducing the concept of atoms as the basic units of chemical reactions.

What is the difference of John Dalton's atomic theory to today's atomic theory?
Although Dalton's theory remains valid in modern atomic theory, there are some differences. Dalton's theory stated that atoms were indivisible and indestructible, but discoveries in modern atomic theory showed that there are subatomic particles that are smaller than the atom. Similarly, through nuclear reactions, an element's atoms can be transformed into atoms of another. Modern atomic theory includes isotopes while Dalton's theory does not have this phenomenon.
What was john Dalton's major constraint when he suggested his Atomic Theory?
John Dalton's major constraint when he suggested his Atomic Theory was the lack of experimental evidence at that time to directly support his ideas. He relied mainly on his observations and reasoning, as the technology to directly visualize atoms was not available during his time.
John Dalton used inductive reasoning to develop his theories. True False?
True. John Dalton employed inductive reasoning to formulate his atomic theory, which was based on observations and experimental data. He gathered evidence from various chemical reactions and gas laws to draw generalized conclusions about the nature of atoms and their behavior. This approach helped him establish foundational principles in chemistry.
Bohr improved upon Dalton's atomic theory?
Yes, Bohr improved upon Dalton's atomic theory by introducing the concept of quantized energy levels for electrons in an atom. He proposed that electrons orbit the nucleus in specific energy levels or shells, which can only hold a specific number of electrons. This model provided a better explanation for the stability and spectral lines of atoms.
Did postulate 4 of Daltons atomic theory holds true now?
No, postulate 4 of Dalton's atomic theory, which stated that atoms of the same element are identical, is not entirely true. We now know that isotopes exist, which are atoms of the same element with different numbers of neutrons. This means that atoms of the same element can have slightly different masses.
Is Dalton's atomic theory true?
not everything.. some are true some are not
Dalton's atomic theory was based on careful measurements and extensive research?
True
Dalton's atomic theory was based on careful measurements and extensive research true or false?
True. Dalton's atomic theory, proposed in the early 19th century, was based on careful measurements of chemical reactions and extensive research into the properties of elements. His theory laid the groundwork for modern atomic theory and helped advance the understanding of the composition of matter.
Which two of the three statements that make up Dalton's atomic theory are no longer regarded as true as stated by Dalton's?
All the atoms in elements are not a like
Is the converse of a true conditional statment is always true?
yes it is
which statment is true of Y chromsomes?
Base
What is Validity Generalization?
a valid geneeralization is a not true statment
What is a statment that is true for any number or variable?
An identity.
Is this statment true or false stride piano style is an example of smooth jazz?
True.
What is one true statment about suicide bombers?
There is no detailed profile.
Is it true that John Dalton proposed that the nucleus was found in the center of an atom?
It is untrue. John Dalton proposed the theory that all matter is made up of individual particles called atoms, which cannot be divided.
Which of these is a true statment about unexploded sub-munitions?
they can detonate from the slightest movement
