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 else can I help you with?
Why is an element's atomic mess not listed as a whole number on the periodic?
Because it is an average of the masses of the isotopes of the element, each of which has a different atomic mass (not mess!)
Why are mass numbers of elements rarely whole?
Mass numbers of elements are rarely whole numbers because they account for the isotopes of an element, which have different numbers of neutrons. The atomic mass listed on the periodic table is a weighted average of the masses of all naturally occurring isotopes, factoring in their relative abundances. As a result, this average often results in a non-integer value, reflecting the contributions of both stable and unstable isotopes.
Why atomic weights are not integers?
Atomic weights are not integers because they represent the average mass of an element's isotopes, weighted by their natural abundance. Isotopes of an element have different numbers of neutrons, resulting in different masses. Since most elements exist as a mixture of isotopes, the atomic weight reflects this variability rather than a single, fixed mass. Additionally, atomic weights are measured in atomic mass units (amu), which are fractional values, contributing to non-integer results.
What mathematical statements are equations you 3x 2 12 9 k 6 m m 105?
None of them because there is no equality sign
How many visitors does discovery cove have per year?
Discovery Cove limits the number of visitors per day to 1000. So that would mean that in any given year they would have over 300,000 visitors. Because of the daily limit it is advisable to make reservations.
What do scientists no longer believe about daltons ideas?
Scientists no longer believe in Dalton's idea that atoms are indivisible and are the smallest particles of matter because further research has shown that atoms can be broken down into even smaller subatomic particles like protons, neutrons, and electrons. Additionally, Dalton's notion that all atoms of the same element are identical has been revised with the discovery of isotopes, which are atoms of the same element with different numbers of neutrons.
How are radioactive isotopes different from isotopes?
Both isotopes and radioactive isotopes are pretty much the same but radioactive isotopes are better because it can be used to make medicine.
Why is the world different because of madame curie?
Madame Marie Curie's achievements include the creation of a theory of radioactivitytechniques for isolating radioactive isotopes, and the discovery of two new elements, polonium and radium. It was also under her direction that the world's first studies were conducted into the treatment of cancers, using radioactive isotopes.
How are arsenic's isotopes helpful?
Arsenic's isotopes are helpful because they fight off cancer.
Statements with superlatives are often false because?
Statements with superlatives are often false because strong statements are easy to disprove.
Is Dakota Boyd related to Jesse James?
yes because Boyds are cousins to the Daltons who are cousins to the James
What do elements of isotopes have differently?
Because of the difference in mass number. Isotopes must have different numbers of neutrons.
Why are isotopes unstable?
because they are moving to Albuquerque
Would isotopes of the same element have the same number of electrons?
Yea because isotopes only differ in their # of neutrons, not electrons
What are the isotopes of cadmium?
See the link below, because cadmium has an enormous number of isotopes: 8 are natural, 30 are artificial.
The various atomic weights of the same element are called?
Atoms of the same element with different atomic masses are known as isotopes. Isotopes differ only by the number of neutrons present in the nucleus of the isotopes. The number of protons is the same for all isotopes of an element (because if there were different numbers of protons, then the atoms would not be of the same element).
Element having maximum number of isotope?
Tin (Sn) has the most number of isotopes with over 30 known isotopes. This is because it has a large atomic number and therefore a greater range of possible isotopes.
