Question

this model represents a lithium ion. image of lithium ion with legend: + proton, ● neutron, - electron complete the sentences. the lithium ion is dropdown charged. the ion would attract a dropdown charged ion and would repel a dropdown charged ion.

Explanation:

Step1: Count protons and electrons

Protons (yellow, +): 3. Electrons (blue, -): 2.

Step2: Determine net charge

Net charge = protons - electrons = \( 3 - 2 = +1 \), so positive charge.

Step3: Apply charge interactions

Opposite charges attract, like charges repel. So positive ion attracts negative, repels positive.

Answer:

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