Juan and Richie spread out some clay on their lab bench. This was to model the earth; soil and rocks. They placed a large ice cube on the clay to model a glacier and they waited for the ice to melt. When the ice turned to water, they mopped it up and there was a depression left in the clay. The boys had modeled a glacier the earth.

answer///carbon;

c. orbital shape i hope this is correct

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.
