A toy car with a mass of 2 kg is moving along the floor at 2 m/s. Calculate its momentum. (1) Write out the appropriate formula
(2) include any calculations made
(3) provide the final answer
(4) Include the correct units for the answer

the answer is true. hope it .

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.
