- One of the best indications of a useful theory is that it raises more questions for further experimentation than it originally answered. How does this apply to Dalton’s atomic theory? Give examples.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_forwardWrite isotope symbols for neutral atoms with the following characteristics: a. Contains 20 electrons and 20 neutrons b. Contains 1 electron and 2 neutrons c. A magnesium atom that contains 14 neutronsarrow_forward
- The existence of isotopes violates one of the original ideas of Dalton’s atomic theory. Which one?arrow_forwardThe symbols for most elements are based on the first few letters of the respective element’s common English name. In some cases, however, the symbol seems to have nothing to do with the element’s common name. Give three examples of elements whose symbols are not directly derived from the element’s common English name.arrow_forwardWhat is the name of the element in Group 4A and Period 5?arrow_forward
- Which of the following is(are) correct? a.40Ca2+ contains 20 protons and 18 electrons. b. Rutherford created the cathode-ray tube and was the founder of the charge-to-mass ratio of an electron. c. An electron is heavier than a proton. d. The nucleus contains protons, neutrons, and electrons.arrow_forwardTitanium and thallium have symbols that are easily confused with each other. Give the symbol, atomic number, atomic weight, and group and period number of each element. Are they metals, metalloids, or nonmetals?arrow_forwardWhich pair of elements do you expect to be most similar? a. Mg and Ca b. N and Cl c. Al and C d. S and Siarrow_forward
