How did Delton describe the relationship between atoms and elements?
Dalton believed that there was a different atom for each element that there was, and that these atoms made up the elements that were in existence. He did not say exactly how these atoms were different, just that they were different. Dalton also believed that all of the atoms for a given element were exactly alike in every way.
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.
What do atoms of the same given element share?
Atoms of a given element always have the same number of protons in their nucleus. Neutrons can vary (in different isotopes) and electrons can vary (in different ions) but protons are always the same for a given element. If the number of protons is changed, then you no longer have the same element.
what are the 4 points in Dalton's atomic theory?
daltons atomic postulations stated that: * 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; the atoms of different elements can be distinguished from one another by their respective relative weights. * Atoms of one element can combine with atoms of other elements to form chemical 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.
Which two of Dalton's theory were incorrect?
These affirmations are not valid today:· All atoms of a given element are identical.· A given compound always has the same relative numbers of types of atoms.

Dalton's atomic theory stated that every element was made of atoms that could not be subdivided atoms of the same element are like and?
Dalton's atomic theory states that elements are composed of indivisible atoms and that all atoms of a given element are identical in mass and properties. Atoms of different elements have different masses and properties.
What are postulates in Daltons atomic theory?
* All elements are made of tiny indivisible particles called atoms. * All atoms of a given element are alike but the atoms of one element differ from the atoms of every other element. * Atoms are not created, destroyed or converted into other kinds of atoms during chemical reactions. They are simply rearranged into new compounds. * Compounds result from the chemical combination of a specific ratio of atoms of different elements. (These are loose interpretations of his original five statements)
Is it true that all particles are alike in elements?
No. All atoms of a given element are alike in the number of protons, which is the atomic number of an element. However, the number of neutrons in the nucleus can vary. Atoms of elements with the same number of protons but different numbers of neutrons are called isotopes. All atoms of a given element in their ground state have the same number of electrons as they do protons, but if they form ions, the number of electrons will increase or decrease, depending on the element, but the number of protons remains the same.
Which of these statements is false all neutrons are alike all electrons are alike all protons are alike all atoms are alike?
True statements: All neutrons are alike, all electrons are alike, all protons are alike (All atoms of a given isotope is only alike). False statement: All atoms are alike All atoms are not alike as they may vary in the number of protons / electrons / neutrons.
Which part of daltons atomic theory are known to be incorrect?
Dalton's atomic theory stated that atoms of a given element are identical in all respects, which we now know is incorrect as atoms can exist as isotopes with different numbers of neutrons. Additionally, atoms were thought to be indivisible, but we now know they can be broken down into subatomic particles like protons, neutrons, and electrons.
What do atoms of the same given element share?
Atoms of a given element always have the same number of protons in their nucleus. Neutrons can vary (in different isotopes) and electrons can vary (in different ions) but protons are always the same for a given element. If the number of protons is changed, then you no longer have the same element.

What are atoms of a given element that have a different number of neutrons?
Isotopes.

The nuclei of all atoms of a given element always have the same number of what?
The nuclei of all atoms of a given element always have the same number of protons. This number is unique to each element and is known as the element's atomic number.
What part Dalton atomic theory was later proved to be incorrect?
Today we know that atoms can be destroyed to nuclear reactions but not by chemical reactions.
