Fluorine has 9 protons and 9 electrons
Iodine has 53 protons and 53 electrons
Answer:
the final product is called a product
Explanation:
Particles of the substance have the most kinetic energy when the substance is(a)1. A gas. The part of the graph that represents where the substance has the least amount of potential energy is labeled(b)1. Solid.
Gas molecules have the highest average velocities among the three states of matter so gas has the highest kinetic energy. During freezing, a substance loses a lot of potential energy so solid has the least potential energy.
The correct answer is 7 I just took the test :)
