Guernica by Pablo Picasso is one of the most emotionally intense works of art, depicting the devastation and horrors of war. The scene I chose to illustrate shows a man with vibrant colors flowing from his mouth, representing the chemical flow of dopamine as he reacts to his surroundings. I focused on the emotion of excitement, which aligns with the burst of activity and urgency in the drawing. I chose this emotion because the bright colors and chaotic energy in both Guernica and our artwork convey a strong sense of stimulation and dopamine. 

I think cultural and historical context shaped scientific discoveries because the only people who significantly impacted the periodic table were all similar in gender and kind of race. If someone of other race or gender had found these discoveries, they may not have been seen as true because of prejudice. Also the main people who found these discoveries were Russian, German, and French. There were translators that were able to spread the knowledge between the similar languages. I do not think there could've been another way things happened though. 

Elements in the same group of the periodic table have the same number of valence electrons, which explains why they have similar chemical properties. As you move down a group, the number of electron shells increases, causing the atoms to get larger. This makes it easier for the outer electrons to be lost (in metals like Group 1) or harder for electrons to be gained (in nonmetals like Group 17). Because of this, reactivity increases down groups for metals and decreases for nonmetals. Other trends, like lower ionization energy, less negative electron affinity, and decreasing electronegativity, all happen because the outer electrons are farther from the nucleus and experience less attraction. These patterns help explain why elements in the same group behave the way they do in reactions.
