Question

the chemical basis of life: atomic structure through chemical reactions
term\tinformation (definition, examples)\tpicture
element\t\tcopper
compound\t\t

Explanation:

To complete the table, we define the terms "Element" and "Compound" and provide examples:

For "Element":

• Definition: A pure substance consisting of only one type of atom. It cannot be broken down into simpler substances by chemical means.
• Examples: Copper (as shown in the picture), oxygen ($\ce{O_2}$), gold ($\ce{Au}$), carbon ($\ce{C}$).

For "Compound":

• Definition: A pure substance composed of two or more different elements chemically combined in a fixed ratio. It can be broken down into its constituent elements by chemical reactions.
• Examples: If the pictures are of water (ice, which is $\ce{H_2O}$) and maybe sodium chloride (table salt, $\ce{NaCl}$), then water is a compound made of hydrogen and oxygen, and sodium chloride is made of sodium and chlorine. Other examples include carbon dioxide ($\ce{CO_2}$), glucose ($\ce{C_6H_{12}O_6}$).

Filling in the table:

Term	Information (definition, examples)	Picture
Compound	Pure substance with two+ elements (fixed ratio); e.g., water ($\ce{H_2O}$), sodium chloride ($\ce{NaCl}$)	Ice (water, $\ce{H_2O}$) and possibly sodium chloride (table salt)
