The option in “the mass of 1me of carbon equals the mass of 1 mole of boron atoms” is false since
Mass=molesx molar mass
And the molar masses of these two elements are different so their masses aren’t equal
The critical thinking step that the student just completed in the situation above is that OF ASKING QUESTION.
Critical thinking refers to the objective analysis of an issue that is undertaken in order to reach a conclusion on a matter. Critical thinking involves asking questions and asking questions make one to discover new things or new phenomenon.

Answer:
1
Explanation:
An unknown element, X, is a nonmetal that contains seven valence electrons. Element X most likely forms <u>1 </u>covalent bond.
Nonmetals gain the electron to complete the octet and form anion. Consider the example of halogen.
When it combine with another halogen atom they form covalent bond. There are seven valance electrons in outer most orbital of halogen atom. By combining with other halogen atom they form one covalent bond and complete the octet.
For example:
Cl atom combine with other Cl atom and form Cl₂.
