Iron Lady
Archaeologists were on a mission looking for ancient artifacts. One day they came across a mysterious tomb deep in the earth. They were very curious as to what was inside it. they estimated the tomb was 5,000 years old. They opened it and found a big, heavy, dense, metal that happened to be shaped like a human. The archaeologists named it "Iron Lady". After the discovery of The Iron Lady they started to experiment with her body remains and found that the metal could be bent or hammered into its final shape at a relatively cool temperature. They also found that if you heated the iron up it would become more brittle and harder. When they would experiment the iron with other metals and carbon and came to find they formed steels which were many times stronger than iron by itself. Once the archaeologists discovered how to create steel the Iron Lady became a very important figure. The inventions of tools and iron weapons. The discovery of the Iron Lady was very useful and successful.

History of the Periodic Table
The history of the periodic table started with John Dalton who had theories on atomic weights. He said that different atoms of different elements have different weights. He observed the weather everyday and came up with 200,000 observations. Dalton was born in Lake District in 1766, he was a reader and a thinker. He came up with the phrase "ultimate particles". Bezalius set out to find the atomic weight of every element. He wanted to find the order on the elements. Bezalius discovered Silicon and found the weight of 45 elements. He was also a glass blower which takes years to master the skill. Wolfgang Doberiner believed chemical reactions could determine the atomic weight of elements. He came up with "triads". Mendeleev discovered the periodic table. He played chemical solitare. His mother's name was Maria and he lost his mom three weeks after arriving in Moscow. Cannizaro said that the densities of volume and gases could determine their atomic weight. Newlands came up with the "Law of Octaves" which meant every eighth element would be similar to the first. He also came up with "Law of Periodicity". Moseley organized the periodic table according to atomic number, he was able to do this because of the discovery of the proton.
Option 2- Dmitri Mendeleev lost his mom three weeks after he arrived in Moscow. His mom wanted him to excel in whatever he did and that is what motivated him to do so. He was able to use adversity to excel in his works because he would want to make his mother proud of what he accomplished. By doing so, this made him very successful in the end.
