The frozen balloon shrank because the average kinetic energy of the gas molecules in a balloon decreases when the temperature decreases. This makes the molecules move more slowly and have less frequent and weaker collisions with the inside wall of the balloon, which causes the balloon to shrink a little.
Answer:
D. Silicon
Explanation:
A anion is a negatively charge ion resulting from the imbalance of protons and neutrons where there are more electrons than protons. Silicon has 4 valence electrons and is more likely to form an ionic bond with another atom(s) that will give it the 4 electrons it needs to become stable.

i would help answer but your post has no diagrams or at least there not showing up
Three ways (out of the many) are:

Hope this helps!! (:
Number of electron determine reactivity
