Certainly! Let's determine if each pair of elements will form a molecular compound held together by covalent bonds and fill in the appropriate data.
### 1. Potassium and Nitrogen
Potassium (K) is a metal and Nitrogen (N) is a non-metal. Typically, metals and non-metals form ionic compounds rather than molecular compounds. Therefore, Potassium and Nitrogen will not form a molecular compound held together by covalent bonds.
Molecular Compound: No
### 2. Carbon and Chlorine
Carbon (C) and Chlorine (Cl) are both non-metals. Non-metals tend to form covalent bonds with each other, resulting in molecular compounds. In this case, Carbon and Chlorine can form several molecular compounds, but the simplest one with the fewest atoms is Carbon Tetrachloride.
Pair will form a molecular compound: Yes
- Chemical Formula: CCl₄
- Name: Carbon Tetrachloride
### 3. Hydrogen and Bromine
Hydrogen (H) and Bromine (Br) are both non-metals. As both are non-metals, they will likely form a molecular compound. The simplest compound they form is Hydrogen Bromide.
Pair will form a molecular compound: Yes
- Chemical Formula: HBr
- Name: Hydrogen Bromide
Let's now compile the information into the table format provided:
\begin{tabular}{|c|c|c|c|c|}
