Chapter 18, Problem 3STP

To determine

The type of bond that holds the atom together.

Answer to Problem 3STP

The correct option is (A).

Explanation of Solution

Given:

The given diagram is

Calculation:

The figure shows the hydrogen and fluorine atom. Hydrogen and fluorine atoms are sharing their electrons and both are non-metals.

The atomic number of hydrogen is 1 and fluorine is 9.

Hydrogen requires 1 electron to complete its outermost shell. Fluorine has 7 valence electrons and fluorine requires 1 electron to get the noble gas configuration.

Therefore, both hydrogen and fluorine shares the electron with each other and form the bond. The kind of bond formed by the sharing of electrons is called a covalent bond.

Hydrogen and fluorine both are non-metal and they are sharing electrons with each other and thus form a covalent bond.

Therefore, the options (B),(C), and (D) are wrong, and option (A) is correct.

Conclusion:

Hence, the covalent bond holds the atoms shown in the above diagram.
