These are electron shell diagrams of three of the most common elements of biological molecules. Which of the the following statements in false?

Please select only one:

(a) the valence shell of nitrogen has 5 electrons.

(b) Each of these atoms has a total of two electrons in the valence shell.

(c) Carbon is the only atom shown here that can form four single covalent bonds and remain a nonpolar molecule.

(d) Carbon is tetravalent element.

(e) None of the above, all the statements are true.

ams of three of the most common elements in biological mo en has five electrons. total of two electrons in the valence shell.

Solution

Option B is false. Because none of the atom has two electrons in the valence shell (outermost shell)
