I have a crush on this boy named Oscar and hes really cute and he's also my neighbor. I've known him since i was about 4 and he was about 6 or 5. I am good friends with his sister too. What should I do???

I think that you should look for signs and do it if you feel like he does like you back  just make him urs ok

you should ask him out if he said no pretend you just wanted to know if he liked you and it was a prank but if he said yeah then date him.

Explanation:

i think is conclusions.i think so

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.
