Concept explainers
(a)
Interpretation:
All valid resonance contributors for the given ion are to be drawn using curved arrows to indicate which pairs of electrons are being shifted.
Concept introduction:
Resonance structure exists in species for which there are two or more valid Lewis structures. Resonance structures are imaginary; true species is represented by the resonance hybrid. Resonance structures differ only in the placement of their valence electrons, not their atoms. For a species, each valid Lewis structure is called a “resonance structure” or a “resonance contributor.” Resonance structures are drawn using curved arrows. The arrow points to the center of an existing bond to represent the formation of a new double/triple bond. A resonance structure can be drawn if a lone pair of electrons on an atom is adjacent with multiple bonds or an incomplete octet on an atom is adjacent to multiple bonds or there is a ring of alternating single and double bonds.
(b)
Interpretation:
Resonance hybrid for the given anion is to be drawn.
Concept introduction:
For a species, each valid Lewis structure is called a “resonance structure” or a “resonance contributor.” A resonance hybrid is a weighted average of all resonance contributors. A partial bond is represented in a resonance hybrid by a dashed line connecting the two atoms.

- 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.
