WebPredict the formula of the ionic compound formed between the lithium ion and the peroxide ion, O 2 2− (Hint: Use the periodic table to predict the sign and the charge on the lithium ion.) Answer: Li 2 O 2 Because an ionic compound is not made up of single, discrete molecules, it may not be properly symbolized using a molecular formula. WebJun 20, 2024 · At this level students only need to know that an ion is a positively or negatively charged particle. However it may be worth introducing students to the electron at this point. When an atom/molecule gains negatively charged electron(s), a negative ion is formed. When an atom/molecule loses negatively charged electron(s), a positive ion is …
