Concept explainers
(a)
Interpretation: The element in the second row of the periodic table that is a halogen, an alkali metal, an alkaline earth metal and a noble gas is to be stated.
Concept introduction: The elements in the periodic table are divided into three classes; metals, metalloids and nonmetals. The elements should be a good conductor of heat and electricity and be ductile and malleable; these are the conditions for the elements to be metals. The elements that are more like nonmetals but under certain conditions, some of the elements can be made to conduct electricity are considered to be metalloids. The elements which are poor conductor of heat and electricity are said to be nonmetals.
To determine: A halogen element in the second row of the periodic table.
(b)
To determine: An alkali metal in the second row of the periodic table.
(c)
To determine: An alkali earth metal in the second row of the periodic table.
(d)
To determine: A noble gas in the second row of the periodic table.

- Help with a periodic table task.' Procedure Part 1: Customizing a Periodic Table Use a textbook or other valid source to determine which elements are metals, nonmetals, metalloids (called semimetals in some texts), alkali metals, alkaline earth metals, transition metals, halogens, and noble gases. Download and print a copy of the Periodic Table of Elements. Use colored pencils, colorful highlighters, or computer drawing tools to devise a schematic for designating each of the following on the periodic table: Group numbers Period number Labels for these groups: alkali metals, alkaline earth metals, transition metals, inner transition metals (lanthanides and actinides), other metals, metalloids (semimetals), other nonmetals, halogens, and noble gases Metals, nonmetals, and metalloids Note: Write the group and period numbers and color/highlight each element for categorization. Be sure to include a key for the schematic.
