    Answer:

    There are 2 lithium atoms in the ionic compound lithium oxide, Li₂O

    Explanation:

    The charge of ions formed by lithium = 1⁺

    The charge of ions formed by oxygen = 2⁻

    In the ionic compound lithium oxide having 1 atom of oxygen, we have;

    For the compound to be electronically neutral, the sum of the charges of the atoms in the ionic compound is zero

    The charge of 1 atom of oxygen in the lithium oxide compound + The charge of the ‘n’ number of lithium atoms in the lithium oxide compound = 0

    ∴ 2⁻ + n × 1⁺ = 0

    n × 1⁺ = 0 – 2⁻ = 2⁺

    n = 2⁺/(1⁺) = 2

    n = 2

    The number of lithium atoms in the lithium oxide compound, n = 2

    Therefore, there are two lithium atoms in the ionic lithium oxide (Li₂O) compound
