Answer:
Noble gases
Explanation:
The noble gases are non-metals that requires the highest amount of energy to remove an electron from their shells.
The reason for this difficult is that their electronic configuration confers a stable configuration them.
- The ionization energy is the energy required to remove the most loosely held electrons in an atom.
- Due to the special stability of noble gases, it is very difficult to remove electrons from an atom of noble gases.

u just have to make sure u have the same number of each type of atom on either side of the equation:)
Answer:
The particles in a solid vibrate in place.
Explanation:
The particles in a solid are close and tightly packed together so they have no room to flow past each other like the particles in a liquid can.
Hope this helps!
Q1. They are highly reactive. Q2. High reactivity, nonmetallic. Q3. Oxygen has an ion charge of -2. Q4. LiCl I believe. Q5. How electrons are shared. Q6 1. Q7. Share 2 valence electrons, I believe.
Answer: heat
Other indicators: color change, odor, gas, temperature change.
