Respuesta :
The correct order of increasing size of the ion [tex]Li^+ < Na^+ < K^+[/tex]
When we progress down a group, the atomic size of the elements increases. Lithium, sodium, and potassium are all group 1A elements. Since lithium is the smallest element and potassium is the largest, when each of them gains a positive charge and loses an electron, lithium will shrink even further in size.
Therefore, ions are ranked according to their increase in size as follows.
[tex]Li^+ < Na^+ < K^+[/tex]
What is an Ion?
- An atom or molecule with a net electrical charge is known as an ion.
- Conventionally, the charge of an electron is thought to be negative; this charge is equal to and opposite to the charge of a proton, which is thought to be positive. Because the total number of electrons in an ion is more than the total number of protons, the net charge of an ion is not zero.
- In contrast to an anion, which is negatively charged but has more electrons than protons, a cation is an ion that is positively charged but has fewer electrons than protons.
- The electrostatic force causes opposite electric charges to be drawn towards one another, causing cations and anions to attract one another and easily form ionic compounds.
