- Given that the periodic table is an organizational scheme for the elements, what might be some other logical ways in which to group the elements that would provide meaningful chemical information in a periodic table of your own devising?arrow_forwardGive two examples of each: a. alkali metal b. alkaline earth metal c. halogen d. noble gas e. metal f. nonmetal g. transition metal h. metalloidarrow_forward2.46 Why are nonmetals important even though they account for only a very small fraction of the elements in the periodic table?arrow_forward
- Are most elements found in nature in the elemental or the combined form? Why? Name several elements that are usually found in the elemental form.arrow_forwardMass spectrometric analysis showed that there are four isotopes of an unknown element having the following masses and abundances: Three elements in the periodic table that have atomic weights near these values are lanthanum (La), atomic number 57, atomic weight 138.9055; cerium (Ce), atomic number 58, atomic weight 140.115; and praseodymium (Pr), atomic number 59, atomic weight 140.9076. Using the data above, calculate the atomic weight, and identify the element if possible.arrow_forwardClassify the following as metals, nonmetals, or metalloids: a.argon b.element 3 c.Ge d.boron e.Pmarrow_forward
