If i blow up a ballon, tie it off, and release it, it will fall to the floor, why does it fall instead of float

The balloon would fall because carbon dioxide, the gas you exhale and blew up with, is denser than air and therefore will fall. Helium however, is less dense than air and floats.

hope this helps :)

its not a choice. you dont choose if you want to be gay or straight.

the electronic configuration of an atom with eight electrons is 1s²2s²2p⁴. the orbital diagrams are shown in the figure.

as per the hunds rule:

1. electrons tend to avoid being in the same orbital as per as practicable.

2. electrons in different orbitals of the same energy will have their spin parallel.

this can be illustrated from the multiplicity of the orbitals of the atom. as there are four electrons in the p orbital and p orbital has 3 sub-shells. the electrons can be fed in different ways as shown in the figure but the correct orbital diagram will be as per the hunds rule.
