A robot spacecraft returned samples from the planetesimal 98765 ALEKS, located in the outer Solar System. Mass-spectroscopic analysis produced the following data on the isotopes of tin in these samples: mass relative isotope (amu) abundance 114 Sm 113.9 98.9% 123.9 1.1% Use these measurements to complete the entry for tin in the Periodic Table that would be used on 98765 ALEKS. Round your entry for the atomic mass to 3 significant digits. the Periodic Table we use here Caution: your correct answer will have the same format but not necessarily the same numbers as the entry f on Earth.

Calculate the atomic mass of each of the following elements using the given data for the percentage abundance and mass of each isotope. a. Lithium: 7.42% 6Li (6.01 amu) and 92.58% 7Li (7.02 amu) b. Magnesium: 78.99% 24Mg (23.99 amu), 10.00% 25Mg (24.99 amu), and 11.01% 26Mg (25.98 amu)
How would you expect the chemical properties of isotopes of the same element to compare to each other? Explain your answer.
One of the best indications of a useful theory is that it raises more questions for further experimentation than it originally answered. Does this apply to Daltons atomic theory? Give examples.
2.84 Early attempts to arrange the elements often focused on atomic weight. Mendeleev considered a number of properties in addition to atomic weight, so he realized that some elements seemed out of place when ordered by atomic weight. Using the modern periodic table, identify elements for which Mendeleev must have had to switch the order in order to get the correct sequence of elements.
Arrange the following in the order of increasing mass. (a) a potassium ion, K+ (b) a phosphorus molecule, P4 (c) a potassium atom (d) a platinum atom
