Dalton pictured compounds as collections of atoms.
For example, nitrogen and oxygen might form a compound containing one atom of nitrogen and one atom of oxygen (written NO), a compound containing two atoms of nitrogen and one atom of oxygen (written N2O), or a compound containing one atom of nitrogen and two atoms of oxygen (written NO2)
Dalton able to predict the formation of multiple compounds between the elements was pictured compounds as collections of atoms.

· Atoms of one element can combine with atoms of other elements to form compounds. · A given compound always has the same relative numbers of types of atoms (this principle is not valid today for all compounds).

Who decided that atoms do not change when chemicals combine into compounds they just change places?
This idea was proposed by John Dalton as part of his atomic theory in the early 19th century. Dalton suggested that atoms combine in fixed ratios to form compounds, and that during chemical reactions, atoms are rearranged but are not created or destroyed.
What reactions is possible according to Dalton's atomic theory?
According to Dalton's atomic theory, reactions involve the rearrangement of atoms to form new compounds, but atoms themselves are not created or destroyed during a chemical reaction. This theory also states that atoms combine in simple ratios to form compounds.
What led Dalton to research to structure of atom?
Dalton's interest was sparked in atoms because he wanted to know why elements combine in specific proportions to form compounds. He was a pioneer in the development of modern atomic theory.
What did Dalton contribute to atomic structure?
Dalton introduced the idea that elements are composed of indivisible particles called atoms, which can combine to form compounds in fixed ratios. He also proposed that atoms of the same element are identical in size, mass, and properties. Additionally, Dalton's atomic theory laid the foundation for the development of modern atomic structure.
Is all matter made of compounds?
No. Substances are made of atoms. Some atoms combine with other atoms to form compounds.
Did Dalton's atomic theory state that atoms of different elements combine in simple whole-number ratios can form compounds?
Yes, Dalton's atomic theory included the idea that atoms of different elements can combine in simple whole-number ratios to form compounds. This concept helped explain the law of definite proportions.
Who siad that atoms of two or more elements can combine to form compounds?
John Dalton
How did dalton explain the formation of compounds?
Dalton proposed that elements combine in simple whole number ratios to form compounds, based on his atomic theory. He suggested that atoms of different elements combine in specific ratios to form compounds, where each compound has a unique composition. This explanation laid the foundation for understanding chemical reactions and the formation of compounds.
Why did john Dalton use the Greek word for invisible to describe atoms?
John Dalton used the Greek word "atomos," meaning indivisible or invisible, to describe atoms because he believed that atoms were the smallest, indivisible particles that made up all matter. Dalton's atomic theory proposed that all elements are made up of tiny, indestructible particles called atoms, which combine in simple whole number ratios to form compounds. The use of the term "atomos" reflected Dalton's belief in the fundamental, invisible nature of these building blocks of matter.
Who decided that atoms do not change when chemicals combine into compounds they just change places?
This idea was proposed by John Dalton as part of his atomic theory in the early 19th century. Dalton suggested that atoms combine in fixed ratios to form compounds, and that during chemical reactions, atoms are rearranged but are not created or destroyed.
Which best describes john Dalton's observations of elements in any given compound?
Dalton discovered that the atoms that combine to form compounds are distinguished from one another by their atomic weights. He also learned that all atoms of a given element are identical.
What did Dalton's experiments show?
Dalton's experiments showed that elements combine in definite proportions to form compounds, supporting the idea of atomic theory. He also proposed that atoms of different elements have different masses, and that chemical reactions involve the rearrangement of atoms.
What reactions is possible according to Dalton's atomic theory?
According to Dalton's atomic theory, reactions involve the rearrangement of atoms to form new compounds, but atoms themselves are not created or destroyed during a chemical reaction. This theory also states that atoms combine in simple ratios to form compounds.
What did John Dalton believed that?
John Dalton believed that all matter is composed of tiny indivisible particles called atoms, and that different elements have different types of atoms. He also proposed that atoms combine in simple whole number ratios to form compounds. Dalton's atomic theory revolutionized the study of chemistry.
What led Dalton to research to structure of atom?
Dalton's interest was sparked in atoms because he wanted to know why elements combine in specific proportions to form compounds. He was a pioneer in the development of modern atomic theory.
According to Dalton's atomic theory what can atoms do in a chemical reaction?
separate from atoms they are attahed to, and combine with other atoms
What evidence convinced John Dalton that elements must be made of individual particles called atoms?
John Dalton was convinced that elements must be made of individual particles called atoms due to his observations of ratios in chemical reactions. He analyzed the ratios at which elements combine with each other to form compounds, and proposed that atoms combine in simple whole number ratios, leading to the development of his atomic theory.
