1. Families of Elements Jefferson Lamar Jones Jr.

2. Alkali metals(potassium) T has 1 valence electron It’s a soft and shiny metal that reacts violently with water. You can not find it in nature pure

3. Alkaline Earth metals(calcium) Calcium has 2 valence electrons Its less reactive than alkali metals Calcium is found in sea shells, bones, and teeth.

4. Transition metals(manganese) Its less active than the other two groups They lose electrons to form +ions They can be stretched, pounded, into different shapes They play vital roles in the human body

5. Boron family(boron) It has 3 valence electrons Boron is used in many different detergents It’s a crystal structure> Rhombohedral

6. Carbon family(carbon) Carbon is the fourth most abundant element on the earth They have 2 electrons and it’s a nonmetal The human body is made up of a lot of carbon

7. Nitrogen family(nitrogen) It was discovered by Rutherford in Scottland in 1772 It is commonly used in ammonia When heated it directly combines with magnesium

8. Oxygen family(oxygen) They are called chalcogens They can be found in nature in both free and combined states. It is the most abundant element

9. Halogen family(halogen) Halogen means salt former It has 7 electrons It exist at all three states and at room temperature

10. Noble gas(radon) Radon is radioactive It’s a indirect decay product of uranium and thorium About 20,000 lung cancers are caused from radon

11. Lanthanides(lanthanum) It’s the first element in the lanthanides It oxides rapidly when it comes it contact with oxygen It reacts directly with carbon, nitrogen, boron, selenium, silicon, phosphorus, sulfur, and halogens

12. Actinides(actinium) Its radioactive It’s the first non-primordial radioactive element to be isolated Its 150 times more radioactive than radium Its found naturally in uranium ores

13. -Hydrogen- It has a single electron It also has a single electron Its never found naturally in nature and pure it can cause serious burns
