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.
Can elements combine to form compounds?
Yes, elements can combine to form compounds through chemical reactions. Compounds are formed when atoms of different elements are chemically bonded together in fixed ratios to create a new substance with unique properties.
Do the atoms in a mixture have a set ratio?
Atoms can interact in different manners. Compounds can have the same ratios of atoms combined in different ways producing different properties (cis and trans forms of compounds come to mind). Additionally, many compounds consist of the same elements but in different ratios. Compare Carbon dioxide, a inert waste product of respiration, to carbon monoxide, a gas deadly to humans. Both use carbon and oxygen, but CO2 has an extra oxygen molecule, greatly changing its properties. So in short, no. Atoms can combine in multiple ratios, and even compounds of equal ratios can come together in different manners to produce different compounds.
What is formed when two or more elements combine?
When two or more elements combine, they form a compound. Compounds are composed of atoms of different elements bonded together in specific ratios.
Is all matter made of compounds?
No. Substances are made of atoms. Some atoms combine with other atoms to form compounds.
Do atoms combine to form molecules in simple whole number ratios?
They do combine in whole number ratios, but these ratios need not be simple - particularly in some organic compounds.
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.
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.
Daltons atomic theory stated that atoms?
atoms are indivisible,tiniest particles of matter. they combine in simple whole no ratios to form elements or compounds. they can neither be created, nor destroyed.
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.

What are ways atoms can combine to form compounds?
The ratio of atoms in different compounds is apparent from the chemical formula. Examples:H2O (water) has 2 Hydrogen for every OxygenH2SO4 (sulfuric acid) has 2 Hydrogen for every 1 Sulfur and 4 Oxygen atoms
Can elements combine to form compounds?
Yes, elements can combine to form compounds through chemical reactions. Compounds are formed when atoms of different elements are chemically bonded together in fixed ratios to create a new substance with unique properties.
What is the relationship between atoms, molecules, and compounds in terms of their structure and composition?
Atoms are the basic building blocks of matter. When atoms combine, they form molecules. Molecules are made up of two or more atoms bonded together. Compounds are substances made up of different types of atoms bonded together in specific ratios. In summary, atoms make up molecules, and molecules make up compounds.
Do the atoms in a mixture have a set ratio?
Atoms can interact in different manners. Compounds can have the same ratios of atoms combined in different ways producing different properties (cis and trans forms of compounds come to mind).

Atoms can combine in multiple ratios, and even compounds of equal ratios can come together in different manners to produce different compounds.
What can be made of atoms that are different or atoms that are alike?
Atoms that are alike can form elements, while atoms that are different can combine to form compounds. Elements are substances made up of only one type of atom, whereas compounds are made up of different types of atoms bonded together in specific ratios.
What is formed when two or more elements combine?
When two or more elements combine, they form a compound. Compounds are composed of atoms of different elements bonded together in specific ratios.
