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.
What did John Dalton get wrong?
Thse affirmations are not considered valid today:· All atoms of a given element are identical. · A given compound always has the same relative numbers of types of atoms.
What part of Daltons atomic theory was then proven to be incorrect?
Two principles not valid today:· All atoms of a given element are identical.· A given compound always has the same relative numbers of types of atoms.
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.
Who proposed the theory that the elements in a compound do not always combine in the same fixed ratio?
The person who stated this was SchrodingerThanks, but do you know what year?

What is the sum of the oxidation numbers in a neutral compound is always?
It should always be ZERO.

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.
What discovery contradict components of Daltons atomic theory?
These ideas are:· "All atoms of a given element are identical" : discovery of isotopes.· "A given compound always has the same relative numbers of types of atoms" : discovery of nonstoichiometric compounds.
The sum of oxidation numbers in a neutral compound is always?
The sum of oxidation numbers in a neutral compound is always zero. (Note that in order for this to be true, the oxidation number of each type of atom present must by multiplied by the number of such atoms present in the formula unit for the compound before the addition is performed.)
Why would you put a hyphen behind a number?
Hyphens are always used in compound numbers like twenty-one.
Does Dalton's 4 of atomic theory exists today?
yes, but only recently have scientist started to accept the atomic theory with sustainable evidence
