Concept 3: Periodic table of elements

Use the periodic table to determine the group of the element, that is a metalloid with 71 neutrons

Antimony

Explain why elements in the same group have similar properties

Elements in the same group have similar properties because they all have the same amount of valence electrons.

Use the periodic table to determine the group of the element, that is the most reactive non metal

Fluorine

Use the periodic table to determine the identity of the element, that is in group 13

boron

Use the periodic table to determine the group of the element, that is the most reactive metal

cesium

Draw the bohr model of oxygen-16

look at the image

Use the periodic table to determine the group of the element, that has 5 valence electrons

nitrogen

Use the periodic table to determine the group of the element, that is in period two, nonmetal, with 6 valance electrons

oxygen

Periods

Use the periodic table to determine the group of the element, that is a gas with two valance electrons and 1 energy level in it's electron cloud.

Hydrogen

Use the periodic table to determine the group of the element, that they do not react in nature

Difference between the characteristics of metals, nonmetals, and metalloids. Include their general location on the periodic table.

Metals are shiny and solid. They are good conductors and located to the left of the metalloids on the periodic table. Nonmetals are the complete opposite of metals. They are dull and brittle but still a solid. On the periodic table they are to the right of metalloids except for hydrogen. Metalloids are also solids and are semi conductors with the other physical properties of metals and chemical properties like nonmetals.

Explain the structures of the electron cloud. include how many electrons are held on each level, where valence electrons are, and which electrons are the craziest.

The electron cloud is outside the nucleus, two electrons can be held on energy level 1, eight electrons can be held on energy level 2 and 3, and eighteen electrons can be held on energy level 4. The valence electrons are always on the outermost shell which is where the electrons are the craziest.

Describe the pattern/shared characteristics of elements in the same groups 1, 2, 3, 3-12, 17, and 18

The pattern is that group 1-3 have the same amount of valence electrons as their group number, 3-12 are transition metals, and group 13-18 have the number of the valence electrons as the number in the ones.
