Answer: A.nitrogen,oxygen,and argon
Explanation:
Answer:
The temperature will decrease
Explanation:
the particles spread out while releasing heat
The atomic cation with +1 charge with the following configuration:
1s22s22p63s23p6
Is Potassium (K+), remember potassium have 19 electrons in its neutral state, when if losses one electrons it becomes + with one less electron, meaning it will have 18 electrons as a cation.
There are 2 electrons in 1s orbital as it can be seen from the electron configuration.
