What temperature units should be used when
performing calculations using
the combined gas law?
A
B
°C only
K only
any
temperature
units can be
used in this
equation

K Only

Explanation:

Pretty sure that we only use Kelvin Scale in gas laws as it provides us with the absolute temperature, this is because in gas laws we are also concerned with motion of particles i.e. kinetic energy and we only use kelvin because 0K means 0 kinetic energy (we cannot do the same using other units)

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.
