Question

this model represents a lithium ion.
complete the sentences.
the lithium ion is charged. the ion would attract a charged ion and would repel a charged ion.

Explanation:

1. First, determine the charge of the lithium ion: Count the number of protons and electrons. Protons (yellow with +) are 3, electrons (blue) are 2. Since protons (positive charge) are more than electrons (negative charge), the ion has a net positive charge.
2. Then, recall the principle of electric charges: Opposite charges attract, like charges repel. So a positive ion attracts a negative - charged ion and repels a positive - charged ion.

Answer:

The lithium ion is \(\boldsymbol{positively}\) charged. The ion would attract a \(\boldsymbol{negatively}\) charged ion and would repel a \(\boldsymbol{positively}\) charged ion.
