Dalton's theory of atoms said that the masses of elements in a compound are always?
equal
Who said this atoms of differnet elements are differnet?
who said this atoms of different elements are different
Who said that all atoms of an element are identical in size mass and other properties?
John Dalton
Which of Jhon Daltons statements about the atom was proven false because of the discovery of isotopes?
Dalton said that all atoms of one element are identical. they are chemically identical but not identical in mass. he did not know of isotopes, which are chemically identical atoms with different numbers of neutral neutrons. ex: all carbon atoms act the same chemically but some mass at 12, others at 14.
He said that compounds are formed when atoms of different elements combine?
Yes, compounds are formed when atoms of different elements chemically bond together. This bonding involves the sharing or transfer of electrons between the different atoms to achieve a more stable configuration. The resulting compound often exhibits different physical and chemical properties compared to its constituent elements.
Who said all elements are made of atoms?
An atom is the smallest unit of any element.
What are atoms of different elements said to be called?
No. Atoms are what make up elements, so they don't count.
The definition of Nonpolar bond on Barron's AP Biology book is electrons are shared equally between two identical atoms. but my teacher said the electrons don't have to be identical.now I'm confused.?
The definition in Barron's book is correct, 100% non polar bond is only possible when two identical atoms form the bond and all the electrons in the universe are identical.
Who said this a given compound always has the same relative numbers and kinds of atoms?

What is the element of atoms?
Atoms are composed of subatomic particles: protons and neutrons in the nucleus, surrounded by electrons in orbitals. Protons have a positive charge, neutrons are neutral, and electrons have a negative charge. The number of protons in the nucleus determines the element's identity.
The elements formed after atoms have broken down and reformed are said to be?
The elements formed after atoms have broken down and reformed are known as isotopes. Isotopes have the same number of protons but a different number of neutrons in their nucleus, leading to variations in atomic mass.
What did John Dalton discover and in what year?
The five main points of John Dalton's atomic theory are as followed: · Elements are made of tiny particles called atoms. · All atoms of a given element are identical. · The atoms of a given element are different from those of any other element. · 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. · Atoms cannot be created, divided into smaller particles, nor destroyed in the chemical process. A chemical reaction simply changes the way atoms are grouped together.The year was 1803.He also discovered the Dalton effect in ophtalmology, a gas law, prepared a list of atomic weights of chemical elements etc.
