Complete the Periodic Table of Elements Warm-up Worksheet 12 minutes!!

Complete Periodic Table of Elements Warm-up worksheet If there are only about 100 types of elements in the world, why are there so many different kinds of matter?

Complete Periodic Table of Elements Warm-up worksheet Elements can combine in many different ways to form many different types of matter.

Complete Periodic Table of Elements Warm-up worksheet Where are the metals, nonmetals, and metalloids located in the periodic table?

Complete Periodic Table of Elements Warm-up worksheet • Metals - are on the left side • Nonmetals – are on the right side • Metalloids – are on a slanting line between the metals and nonmetals

Complete Periodic Table of Elements Warm-up worksheet Which group of elements on the periodic table does not readily combine with other elements?

Complete Periodic Table of Elements Warm-up worksheet Group 18 - the Noble Gasses

Complete Periodic Table of Elements Warm-up worksheet Describe metalloids.

Complete Periodic Table of Elements Warm-up worksheet Elements having properties of both metals and nonmetals.

Complete Periodic Table of Elements Warm-up worksheet Germanium, with an atomic number of 32, is not a metal or a non-metal, but a metalloid.– Describe where metalloids are found on the periodic table, with respect to the metals and non-metals.

Complete Periodic Table of Elements Warm-up worksheet Metalloids are found in between metals and non-metals on the periodic table. Their position tells us that they have some of the characteristics of metals and some characteristics of non-metals. For example, germanium conducts electricity, but not as well as true metals.

Complete Periodic Table of Elements Warm-up worksheet Elements are organized in the periodic table in such a way that there are patterns of elements placed close together that have similar properties. For example, knowing the properties of one element in a column of the periodic table will help a person predict the properties of other elements in that same column.–Describe two properties common to elements found at the far left of the periodic table.–Describe two properties common to elements found at the far right of the periodic table.

Complete Periodic Table of Elements Warm-up worksheet On the far left side of the periodic table the elements are all metals. So, they are solids at room temperature and are good conductors of heat and electricity.One the far right side of the periodic table, the elements are gases at room temperature. They are colorless and non-reactive.

I.S. Learning Goal: • I can describe the features and components of the atom.

FORCES IN THE ATOM Complete Forces of an Atom Graphic Organizer • Gravitational Force • Electromagnetic Force • Strong Force • Weak Force

Gravitational Force Complete Forces of an Atom Graphic Organizer • The force of attraction of objects due to their masses • The amount of gravity between objects depends on their masses and the distance between them Do you think this force plays a significant role in holding the atom together?

Complete Forces of an Atom Graphic Organizer Electromagnetic Force • The force that results from the repulsion of like charges and the attraction of opposites • The force that holds the electrons around the nucleus + + + - - - Notice how the particles with the same charge move apart and the particles with different charges move together. Why are neutrons not pictured above?

Complete Forces of an Atom Graphic Organizer Strong Force • The force that holds the atomic nucleus together • The force that counteracts the electromagnetic force Notice how the electromagnetic force causes the protons to repel each other but, the strong force holds them together. + + + + If you need help remembering strong force, just think of… Would an atom have a nucleus if the strong force did not exist? Mr. Jones

Weak Force • This force plays a key role in the possible change of sub-atomic particles. • For example, a neutron can change into a proton(+) and an electron(-) • The force responsible for radioactive decay. • Radioactive decay process in which the nucleus of a radioactive (unstable) atom releases nuclear radiation. Notice how the original particle changes to something new. + n - If you need help remembering weak force, just think of… Mike N.

Complete Atomic Basic Worksheet

Bohr Diagrams Review • Draw a nucleus with the element symbol inside. • Carbon is in the 2nd period, so it has two energy levels, or shells. • Draw the shells around the nucleus. C

Bohr Diagrams Review • Add the electrons. • Carbon has 6 electrons. • The first shell can only hold 2 electrons. C

Bohr Diagrams Review • Since you have 2 electrons already drawn, you need to add 4 more. • These go in the 2nd shell. • Add one at a time -starting on the right side and going counter clock-wise. C

Bohr Diagrams Review • Check your work. • You should have 6 total electrons for Carbon. • Only two electrons can fit in the 1st shell. • The 2nd shell can hold up to 8 electrons. • The 3rd shell can hold 18, but the elements in the first few periods only use 8 electrons. C Complete Atomic Basic Worksheet

I.S. Learning Goal: • I can apply models to features of an atom

Lewis Structures Review • Find out which group (column) your element is in. • This will tell you the number of valence electrons your element has. • You will only draw the valence electrons. www.chem4kids.com

Groups - Review Group 8 = 8 electrons Group 1 = 1 electron Except for He, it has 2 electrons Group 2 = 2 electrons • Each column is called a “group” 3,4,5,6,7 • Each element in a group has the same number of electrons in their outer orbital, also known as “shells”. • The electrons in the outer shell are called “valence electrons” www.chem4kids.com

Lewis Structures Review • Write the element symbol. • Carbon is in the 4th group, so it has 4 valence electrons. • Starting at the right, draw 4 electrons, or dots, counter-clockwise around the element symbol. C

Lewis Structures Review • Check your work. • Using your periodic table, check that Carbon is in the 4th group. • You should have 4 total electrons, or dots, drawn in for Carbon. C Complete Lewis Structure Notes Worksheet and Atomic Basic Worksheet SHOW FOR A STAMP WHEN DONE!
