In an alternate universe, the smallest negatively chargedparticle, analogous to our electron, is called a blorvek. Todetermine the charge on a single blorvek, an experiment likeMillikan’s with charged oil droplets ‘as carried out, and thefollowing results were recorded:
(a) Based on these observations, what is the largest possiblevalue for the charge on a blorvek?
(b) Further experiments found a droplet with a charge of

- 2-89 Assume that a new element has been discovered with atomic number 117. Its chemical properties should be similar to those of astatine (At). Predict whether the new element’s ionization energy will be greater than, the same as, or smaller than that of: (a)At (b)Raarrow_forwardWhich of the following is true about an individual atom? Explain. a. An individual atom should be considered to be a solid. b. An individual atom should be considered to be a liquid. c. An individual atom should be considered to be a gas. d. The state of the atom depends on which element it is. e. An individual atom cannot be considered to be a solid, liquid, or gas. Justify your choice, and for choices you did not pick, explain what is wrong with them.arrow_forward2.84 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.arrow_forward
