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.
Because it is an average of the masses of the isotopes of the element, each of which has a different atomic mass (not mess!)
None of them because there is no equality sign
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.
He discovered it because he was a very great mathematician of ancient history. He was smart and developed the discovery of Pi to better the world as it is today.
Zero was not discovered because it was conceived by ancient mathematicians thus making arithmetic easier for positional place value purposes as for example 23 is different to 203.
Both isotopes and radioactive isotopes are pretty much the same but radioactive isotopes are better because it can be used to make medicine.
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.
Arsenic's isotopes are helpful because they fight off cancer.
Statements with superlatives are often false because strong statements are easy to disprove.
yes because Boyds are cousins to the Daltons who are cousins to the James
Because of the difference in mass number. Isotopes must have different numbers of neutrons.
because they are moving to Albuquerque
Dalton's symbols are not used in chemistry because it is very difficult to represent in chemistry
Yea because isotopes only differ in their # of neutrons, not electrons
See the link below, because cadmium has an enormous number of isotopes: 8 are natural, 30 are artificial.
No. Because Al has a large no. of isotopes. (i think 22 isotopes).
Isotopes of an element have different masses because their nuclei have different numbers of neutrons.
