Concept explainers
An element is a shiny, silver-colored solid at room temperature and pressure. It conductselectricity and can be found in nature in its pure form. Whichelement on the periodic table (a−d) would have these properties?
Interpretation:
Whether the element is metal, nonmetal, and semimetal should be classified. Also, the general location of element in periodic table should be determined.
Concept introduction:
Periodic table represents a systematic arrangement according to element’s physical as well as chemical properties. Here, elements are represented as a two-letter symbol and are arranged in increasing order of atomic number. Periodic table contains 18 groups (columns) and 7 periods (rows). In periodic table, groups from 1-2 and 13-18 are called main group elements. The 10 middle groups from 3-12 are known as transition elements. There are also 14 elements that started with lanthanum are called lanthanides and 14 elements started with actinium are known as actinides.
Explanation of Solution
The metals are characterized by their silvery shiny appearance and good conductor of electricity and given elements is a silvery shiny and good conductor of electrical energy (electricity), therefore the given element must be a metal. Metals that are occurred in pure form in nature known as native metals and native metals are silver, gold, and copper. Among these metals, silver is the only metal that has a silver coating. Hence the given metal is silver.
The silver metal present in periodic table in 11th group and 5th period, therefore, the location of given silver metal is b.

- Differentiate between metal and non-metal on the basis of their chemical properties.arrow_forwardIt is possible to define metallic character as we do in this bookand base it on the reactivity of the element and the ease withwhich it loses electrons. Alternatively, one could measure how well electricity is conducted by each of the elements todetermine how “metallic” the elements are. On the basis ofconductivity, there is not much of a trend in the periodic table:Silver is the most conductive metal, and manganese theleast. Look up the first ionization energies of silver and manganese;which of these two elements would you call moremetallic based on the way we define it in this book?arrow_forwardThe reaction of barium with sulfur is similar to that of magnesium with sulfur.
