Answer:
B
Explanation:
Economic principles has nothing to do with biome determination.
Answer: 2:2 but if simplified it’s 1:1
Explanation:
Answer:
C. It is reactive because it must gain two electrons to have a full outermost energy level.
Step-by-step explanation:
The electron configuration of this element ends in 2s²2p⁴.
A filled energy level would end in 2s²2p⁶.
The element will be reactive, because it must gain electrons to have a full energy level, and it needs two more electrons to do this.
There would be eighteen bonding electrons
6 Atoms!
Mg = 1 atom.
O = 4 atoms.
A = 1 atom.
