Place the atoms relative to each other. Place the atom with group number in the center because it has the electronegativity. If atoms have the same group number, place the atom with the period number in the center.

Place the atoms relative to each other. Place the atom with lower group number in the center because it has the lower electronegativity. If atoms have the same group number, place the atom with the higher period number in the center.

Explanation:

Generally, electronegativity increases from left to right within a period (horizontal rows in the periodic table), and decreases from top to bottom within a group (vertical columns).

hope this

explanation:

covalent bonds

consist of pairs of electrons shared by two atoms, and bind the atoms to fixed orientation and requre high energies to break them

ionic bonds

when two atoms differ considerably in their electronegativity, then one of the atoms will lose its electron to the other atom. this results in a positively charged ion(cation) and a negatively charged ion (anion)

c) should be the answer.
