Explanation:
When people think about the first people in America, they might think of Christopher Columbus or the European colonists; when, in fact, the first people were the Indians. The Cherokee Indians had lived in the lands of what is now the United States for thousands of years before any colonists had ventured over. Little did they know that the new nation that was going to be forming around them, would severely affect the lives of their descendents.
Life before the Trail of Tears but after the arrival of the new Americans was more or less simple for the Cherokees. They spend time hunting and fishing. Some of them even worked on plantations and even owned their own slaves, in an effort to accommodate some of the American ways of living.
this is the rough draft but it needs more if you know anyone who can help it's much appreciated :)

Answer:
Crystals can be of many types.
Explanation:
- Covalent crystals are crystals whose atoms are connected with covalent bonds.A Covalent bond exists where the atoms share electrons. These bonds are extremely strong and very hard to break. Because of this, the crystals themselves are also very strong and have high melting points. Imagine gluing together beads with super glue.An example of a covalent crystal is a diamond.
- Ionic crystals are crystals whose atoms are held together with ionic bonds, or charged bonds. With these ionic bonds, one atom is negatively charged and is attracted to other atoms in the crystal that are positively charged.
- Metallic crystals are crystals made of metal elements. These crystals sparkle with the lustrous sheen we think of metals having.
