B ia the correct one .
Hydrogen only uses the first energy shell, which holds 2 electrons, not 8.
Answer:
N - 1s²2s²2p³
Explanation:
Nitrogen is located in the p-block of the periodic table (groups 13-18) and is on the 2nd period.
The 2nd period tells us the principal energy level (a quantum number) is n = 2. Therefore, it must have already filled up the 1s sublevel.
The groups 13-18 on period 2 tells us that the 2s sublevel is also filled.
Nitrogen is located in Group 15. That means that there are 3 electrons that have filled the 2p sublevel, out of a possible 6.
Therefore, our electron configuration is 1s²2s²2p³
2p³ (Shorthand Config)
[He] 2s²2p³ (Noble Gas Config)
C. because it doesn't break down without chemicals, so it would eventually just pile up.
Answer:
It is the distributions of electron on the three levels
Explanation:
The three levels are : K . L . M . N
When lithium reacts to chlorine it goes from having no charge to +1 charge, while chlorine goes from neutral to having -1 charge.
