All the tools & learning materials you need for study success - in one app.
Get started for freeWrite formulas for and name the binary hydrogen compounds of the second-period elements (Li to F). Describe how the physical and chemical properties of these compounds change from left to right across the period.
Explain why alkali metals have a greater affinity for electrons than alkaline earth metals.
Use the alkali metals and alkaline earth metals as examples to show how we can predict the chemical properties of elements simply from their electron configurations.
Explain why, for isoelectronic ions, the anions are larger than the cations.
Use the second period of the periodic table as an example to show that the size of atoms decreases as we move from left to right. Explain the trend.
