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 molybdenum in these samples: esc isotope ! 1 Use these measurements to complete the entry for molybdenum in the Periodic Table that would be used on 98765 ALEKS. Round your entry for the atomic mass to 2 significant digits. 92 Mo 95 Mo Caution: your correct answer will have the same format but not necessarily the same numbers as the entry for molybdenum in the Periodic Table we use here on Earth.

Adding or removing water will change the concentration of a solution. O True O False

If the nucleus of an atom took up 50% of the volume (instead of 0.1%) what do you think the scatter plot of the particles would look like? (Imagine the detector unrolled so that 180 degrees shows particles going straight through and O degrees and 360 degrees show particles that bounce right back to the detector.) 1. 180 360
