Question

1. use the periodic table to choose the best answer. what is the formula for this compound, triphosphorus dioxide? o p(iii)o o p₃o o po o p₃o₂ 11. choose the best answer using a periodic table. which type of bond forms between lithium (li) and sulfur (s) atoms? covalent bond ionic bond hydrogen bond metallic bond

Explanation:

Step1: Analyze triphosphorus dioxide

The name "triphosphorus dioxide" means 3 phosphorus (P) atoms and 2 oxygen (O) atoms.

Step2: Write the chemical formula

Combine the atom counts: $P_3O_2$

Step3: Analyze Li and S bonding

Lithium (Li) is a metal, sulfur (S) is a nonmetal. Metals and nonmetals form ionic bonds.

Answer:

1. $\boldsymbol{P_3O_2}$
2. $\boldsymbol{ionic\ bond}$
