Answer:
d) repeat
Explanation:
If the trend in a property is periodic, it means it will repeat on the periodic table.
Periodic properties on the table have a constant pattern as we move up or down a group or across a period from left to right.
- This helps to predict some of the salient properties of elements as we move through the periodic table.
- For example, on most periodic groups, metallicity increases as we move down the group and it decreases across the period.

Answer:
Multivalent Ionic
Explanation:
The type of bond formed between the atoms of two elements can easily be deduced from the magnitude of electronegativity difference between the two bonding atoms.
A summary of electronegativity differences and corresponding types of bonds are shown below as adapted from chemlibretexts, where Δχ is the difference in electronegativity ;
ionic if Δχ ≥ 2.0
polar if 2.0 > Δχ > 0.5
nonpolar if 0.5 > Δχ
To determine the type of bond between Hg and F. Hg has an electronegativity of 2 while F has an electronegativity of 4. the difference in electronegativity (Δχ) is 4 - 2 = 2
This corresponds to a multivalent ionic bond because mercurous ion is the
Hg2^2+ ion and this leads to the formation of Hg2X2 (mercury I fluoride).
