I have a balloon below and I squeeze it until it is about to pop. This is decreasing the volume. What happens to the pressure inside? What are the molecules doing inside?

Pressure goes up

Explanation:

The pressure is inversely proportional to the volume.  So when volume is decreased the pressure rises.

The molecules are getting pushed closer together and more collisions occur which will also increase the temperature.

"among the transition metal elements, manganese and zinc have a slight lowering of electronegativities. the reason behind this is that the nuclear charges of these elements are slightly weaker than the other transition metal elements due to the way their valence electrons are filled up. both manganese and zinc have their valence electrons filled up to the 4th shell with 1 pair of electrons (4s2) completely occupying it. although the electrons in the 3rd shell (3d) are yet to be paired since the outer most shell is filled up, the ability of the nucleus to attract electrons is lessened. hence,   the electronegativity (or the ability to attract electrons) is lessened."
