What else can I help you with?
Dalton hypothesized that atoms are indivisible and that all atoms of an element are identical. It is now known that?
Because the existence of isotopes was discovered not all atoms of an element are identical.
Are beryllium atoms identical?
Each atom of an isotope of beryllium (or of another element) is different from the atoms of an other isotope. But all the atoms of an isotope are identical.
Are all electrons of all atoms the same?
Of corse,all electrons are identical all protons and neutrons are also identical
The number of these must be the same for all atoms of an element?
The number of protons is identical in all atoms of an element.
What makes all atoms of an element the same?
atoms are of an element are the same becasue the are all made from identical particles. there is no way to distinguish one electron from another electron. the same is true for neutrons and protons. so by virtue of the fact that its constituents are identical, all atoms of the same element are identical.
What was one idea Dalton taught about atom?
All atoms of one type were identical in mass and properties. (Apex 2021)
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.
What was idea Dalton taught about atoms?
All atoms of one type were identical in mass and properties. (Apex 2021)
Which of Dalton's atomic theory is not supported?
Atoms are indivisible and indestructible, and all of the atoms of a given element are identical in mass.
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.
How are atoms identical?
they are not identical. Dalton's model was wrong.
A substance in which all of the building block particles are identical is called?
An element. The particules are atoms.
