Their periodic table is organized very much like ours. The only difference is each shellcan hold a maximum of five electrons. The family number tells us the number of electrons in the outermost shell.Help decode the slogan by filling in the table with the correct element into their corresponding places.

List the characteristic physical properties that distinguish the metallic elements from the nonmetallic elements.
2.84 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.
Questions 31 through 36: Percentage abundances and atomic masses (u) of the natural isotopes of an element are given. a Calculate the atomic mass of each element from these data. b Using other information that is available to you, identify the element.

An ion that has two more electrons outside the nucleus than there are protons in the nucleus will have a charge of_________.
How would you expect the chemical properties of isotopes of the same element to compare to each other? Explain your answer.
Titanium 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?
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.
Copper (Cu) has an atomic number of 29 and a mass number of 64. One copper atom, therefore, has how many protons? a.27 b.29 c.31 d.35
Which of the following statements is/are true? For the false statements, correct them. a. All particles in the nucleus of an atom are charged. b.
