The correct statement about lithium sulfide is: The atoms in lithium sulfide are held together by bonds.
The correct statement about lithium sulfide is that the atoms in lithium sulfide are held together by bonds.
To determine this, we can consider the composition of lithium sulfide. The chemical formula for lithium sulfide is Li2S, indicating that there are two atoms of lithium (Li) and one atom of sulfur (S) present.
Since lithium has a valence of +1 and sulfur has a valence of -2, they will form ionic bonds to achieve stability. This means that lithium will lose one electron to form a positive ion (Li+), while sulfur will gain two electrons to form a negative ion (S2-).
The positive lithium ions and negative sulfur ions will then be attracted to each other, forming ionic bonds. These bonds involve the strong electrostatic attraction between the opposite charges of the ions, resulting in the formation of a crystal lattice structure.
So, the correct statement is that the atoms in lithium sulfide are held together by bonds, specifically ionic bonds.
