Answer/Explanation:
Heat from the sun hits the ground and is absorbed. The higher you go, it gets more colder due to the fact that the air doesn't hold onto the radiation as it goes straight through the ground, which is why the top of mountains are very cold, and people are able to die in minutes.
Explanation:
- F Cl Br
- ionization energy decreases we move down the group
- so Br<Cl<F
2. Na K Li
- ionization energy decreases we move down the group
- so K<Na<Li
3. C N O F
- ionization energy increases as we move across the peroid
- so C<N<O<F

Answer:
2
3
Explanation:
To infer the last energy of the given atoms, we need to write their electronic configuration:
For N = 1S² 2S² 2P³
Mg = 1S² 2S² 2P⁶ 3S²
The energy levels are usually designated as;
n = 1
n = 2
n = 3
n =4
For N, the last energy level is 2
Mg, the last energy level is 3
We can also determine this number by the periods the atoms can be found.
Answer:
energy
