A student calculates the atomic mass of sulfur to be 32.05 amu. His teacher reviews the student's work and suggests that he also account for sulfur-36, a very rare isotope that has atoms of mass 35.967 amu. By accounting for sulfur-36, how will the student's new calculation of atomic mass compare to the original calculation? It will increase very slightly, if at all.

It will increase by about 1 or 2 amu.

It will decrease by about 1 or 2 amu.

It will increase by about 3 or 4 amu.

The atomic radius of sodium is 186 pm and of chlorine is 100 pm. the ionic radius for na+ is 102 pm and for cl– is 181 pm. in going from na to cl in period 3, why does the atomic radius decrease while the ionic radius increases? a. the inner electrons in the sodium cation shield its valence electrons more effectively than the inner electrons in the chloride anion do. b. the inner electrons shield the valence electrons more effectively in the chlorine atom than in the chloride anion. c. the outermost electrons in chloride experience a smaller effective nuclear charge than those in the sodium cation do. d. the outermost electrons in chloride experience a larger effective nuclear charge than those in the sodium cation do. e. monatomic ions are bigger than the atoms from which they are formed.

What best discribes the relationship between wavelength and frequency in a electromagnetic wave

How is energy related to the change of state represented by the model? atoms gain energy as a solid changes to a liquid. atoms gain energy as a solid changes to a gas. atoms lose energy as a solid changes to a liquid. atoms lose energy as a solid changes to a gas.
