Question

Which of the following atoms has arranged in a regular geometric pattern?

• A. $Na{C}_2{H}_3{O}_2\left(s\right)$
• B. $H_{2}O\left(l\right)$
• C. $Ar\left(g\right)$
• D. $NaCl\left(aq\right)$
• E. $C{H}_4\left(g\right)$

Answer 1

The correct option is A $Na{C}_2{H}_3{O}_2\left(s\right)$

$Na{C}_2{H}_3{O}_2$ is a solid in which molecules arrangement is regular and close to each other. Random motion does not exit like liquids and gases so it has a regular geometric pattern.
