Ernest Rutherford contributed to the atomic theory by discovering that the atom is mostly empty space.
He can to that conclusion because he fired alpha particles at gold foil, which was so thin that it was only around .00004 cm thick, and while almost all shot straight through, some actually bounced back!
He likened it to shooting a 15-inch round(bullet) at tissue paper, only to have it bounce right back at you! Based on this, he theorized that the atom is mostly empty, which is why a majority of the particles passed right through, but in the very center of the atom there is a super-dense structure called a nucleus that held a majority of the atom's mass. This super-dense mass would be more than massive enough to deflect the particle, should they collide.

Explanation:
1. The passage explains the conflicts and disagreements that existed between the Mexicans and Americans before the start of the Mexican-American war. The two nations failed to agree on a defined boundary for Texas. The following statement supports this fact, "In 1844, annexation was negotiated between Texas and the U.S. with an important wrinkle: the southern boundary was the Rio Grande. This border had been rejected by the Mexican Congress in favor of the Nueces River farther north." This disagreement formed the basis of the war.
2. The United States was not justified in going into war with the Mexicans. The measures Polk used in resolving this matter appears deceitful and not straightforward. Placing military presence in California when the two nations had not agreed to terms and even offering bribe to an exiled dictator, were not good ways of reaching to terms.
Answer:
Five reasons ranked, why India would be attractive.
1. Very large population since ancient times - this simply means: more people to extract taxes from, since the main goal of an empire is to conquer many lands and ethnicities, in order to take economic resources from them.
2. Strategic geographic location - India has access to both sides of the Indian Ocean, and it can connect the Middle East with Southeast Asia, this is very important for trade.
3. Central location for trade - as said before, India is almost in the middle of Asia, and it is a central place for many trade routes between East Asia, the Middle East, and Europe.
4. For defensive purposes - a neighboring country may feel that India is a threat, and decide to simply conquer it.
5. Prestige - India was an ancient, diverse culture, and ruling India, being the Emperor of India, will always be a prestigious position.
3. Explain which reason you think was most important and why you think that.
The most important reason is the large population. India has been one of the most populated countries since anciet times because the land is very fertile. More people = more taxes, and the main goal of an empire is to take taxes from the people that it rules.
