Part A Use the pump handle to add some gas molecules to the container. The amount is up to you. Change the volume of the
box, and heat or cool it as you like. If you accidentally blow the lid off, click the Return Lid button. In the data table, recor
the pressure (P), length (Y), number of gas molecules (n), and temperature (1). Then click the reset button, change all of
the variables, and again record the measurements. Repeat this process until you have five sets of measurements.

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.

the seeing the electronic configuration we can say that the element is fluorine.

fluorine is the most electronegative element in the periodic table.

but by only seeing the configuration we cannot say about its reactivity because we don't know if its configuration after excitation or by addition of electrons.

but if not then, it is the lightest halogen and exists as a highly toxic pale yellow diatomic gas at standard conditions. as the most electronegative element, it is extremely reactive: almost all other elements, including some noble gases, form compounds with fluorine.
