<span>Ionization energy (IE) is the amount of energy required to remove an electron.
If you observe the IEs sequentially, there is a large gap between the 2nd and 3rd. This suggests it is difficult to remove more than 2 two electrons. Elements that lose two electrons to become more stable are found in the Group 2A (2 representing the number of electrons in the outermost valence shell).</span>
Answer:
1000g
Explanation:because the higher mass takes up heat.
I believe the answer is Limestone
Limestone is one of the vital minerals that is used to make cement. It is a sedimentary rock composed mostly of the calcium carbonate and, according to mineral coalition, it comprises about 15% of the Earth's sedimentary crust.
Answer:
D
Explanation:
It could come from anybody of water around you that had some water evaporated.
Answer:
The number of energy levels increases as you move down a group as the number of electrons increases. Each subsequent energy level is further from the nucleus than the last. Therefore, the atomic radius increases as the group and energy levels increase. Hope this helps!
Explanation:
um same as the answer...?
