Calculate: A year is the time it takes a planet to complete one orbit. Use your data to estimate the Year length for each planet. Use time units of Earth years or Earth months. Why does it take the outer planets so long to orbit the Sun? Try to come up with 2 reasons. Plzz huryy up

the answer is 1 i believe

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.
