The periodic table contains groups and periods that include the elements. For group 1 metal lithium is least likely to lose an electron.
<h3>What are group 1 metals?</h3>
Group 1 metals are the alkali metals that include, Li, Na, K, Rb, and Cs. They show the property exhibited by the metals. The chemical trends of group 1 show that cesium loses an electron more easily than the other elements.
When going down the group the tendency to lose electrons increases as the atomic radius increases. The electron gets far away from the nucleus making it easy to get removed.
Therefore, lithium being the first element of the group has the smallest radii and is least likely to lose an electron.

Answer:
B
Explanation:
One of the main problems is the soil erosion reducing the fertitlity of the soil, thus reducing it's chances of the soil helping plant growth, thus reducing biodiversity. The other selections worsen the problem.
Assuming we have 100 g of sample
30.45/MW of N 14g = 2.175
69.55/MW of O 16g = 4.34
4.34/2.185 = 2
for every 1 mole of N we have 2 moles of O
so the empirical formula would be NO2
without having the molecular weight of the entire molecule the molecular formula can not be determined with the information in your question
