Write a short biography of your element, include its birth date (discovery), it’s country of origin (where it was discovered), interesting facts about where it is found and why it is in the group/family on the periodic table.

April 16 Day 3 DRQ: Use the periodic table to find a element whose atoms have five outer-level electrons, one with three outer electrons and one with four outer electrons. Activities: DRQ\Review DRQ Atoms and Elements Mini-Quiz The Periodic table notes Closure: Another interactive periodic table Homework: Write a short biography of your element, include its birth date (discovery), it’s country of origin (where it was discovered), interesting facts about where it is found and why it is in the group/family on the periodic table.

Atoms and Elements Mini-Quiz Put your name date and class period at the top right of a half-sheet of paper Number down the left, 1-10 skip a line between each. If the statement is true, answer true. If the statement is false, correct the underlined word to make it true.

Quiz 1-5 If the statement is false, correct the underlined word to make it true. Atoms are made up of protons, neutrons and electrons. Protons and neutrons have an electric charge. Electrons and protons are found in the nucleus of an atom. If you change the number of neutrons in the center of an atom, you change the type of element. The atomic number is equal to the number of protons and electrons in an atom.

Quiz 6-10 If the statement is false, correct the underlined word to make it true. All elements, except Hydrogen, have two electrons in the first energy level. Chemical symbols can be one, two or three letters. The first letter of a chemical symbol is always capitalized. Elements at the bottom of the periodic table are heavier than elements at the top. The electrons in an atom are attracted to the nucleus because of the neutrons.

Notes on the periodic table. Get out your periodic table. Follow along as I show you how the periodic table is organized on the overhead. I will post a pdf of the overhead notes on the wiki this afternoon. For now, make sure you copy what I write so that if you have questions you can come see me.

Periodic table notes By mid-1800’s 60 elements were known. There was a lot of information about these elements, but it was not organized. 1869- Russian scientist Dmitri Mendeleev made a chart of the know elements. We have added elements to his chart as we discovered more.

The current periodic table

Element arrangement In the periodic table, the elements are arranged in order of their atomic numbers Except for a few, atomic numbers are in the same order as atomic masses. The lightest element has the lowest atomic number, the heaviest element has the highest atomic number Hydrogen has an atomic number of 1, Aluminum has an atomic number of 13. Aluminum is heavier than Hydrogen.

Rows = “PERIOD” Each row across the periodic table is called a period. All the elements listed in a row belong to the same period. How many periods are in the modern periodic table?

Column = “GROUP” or “FAMILY” Each column in the periodic table is called a group, or family. All of the elements in a group have many similar properties. Each group is identified by a number. For example, the column of elements at the left side of the table is Group 1.

Metals and Nonmetals Elements can be divided into two types A heavy step-like line can be used to divide the two. Metals There are more metals Metals are on the left Nonmetals Fewer non metals Nonmetals are on the right.

April 17 Day 4 DRQ: Use the periodic table to list a metal, a metalloid and a nonmetal each with five outer-level electrons. Activities: DRQ\Review DRQ Groups/Cooperative learning – Our own periodic table Using the atoms created on Tuesday and Wednesday, make a periodic table in our room on the wall. In groups, complete any elements that are missing. Closure: Checking Concepts Questions 1-10 page 294 Homework: Using your notes from 10-1 to 10-3 and the notes from today, create a study guide about atoms, elements and the periodic table.
