Write the names of Group 1, Group 7, and Group 0 elements

Group 1 Elements

​The alkali metals are all soft, shiny and metallic when cut.

They react vigorously with water.

They have low melting points.

They have low densities.

They are good conductors of electricity.

​​Properties of Alkali Metals

​Group 1 elements include the ALKALI METALS, Li, Na, K, Rb, Cs, Fr.

Multiple Choice

What gas is given off when group 1 elements reacts with water?

• Oxygen

• Carbondioxide

• Hydrogen

• Water vapor

Multiple Select

(More than one answer)

• Silvery solids

• Very hard metals

• Very soft metals

• High density

• Low density

Fill in the Blanks

The melting and boiling points of the Group 1 elements

as you go down the group.

The elements in group 7 are called halogens. They are Fluorine (F), chlorine (Cl), bromine (Br), iodine (I), astatine (At)

​​Group 7 Elements

They have low boiling and melting points.

The halogens react with metals to produce salts. For example, chlorine reacts with sodium:

sodium + chlorine → sodium chloride

The halogens become less reactive going down group 7.

Properties

Halogen displacement reactions

A more reactive halogen can displace a less reactive halogen from solutions of its salts.

For example, chlorine is more reactive than iodine. A solution of chlorine can displace iodine from potassium iodide solution:

chlorine + potassium iodide → potassium chloride + iodine

Multiple Choice

What name is given to elements in Group 7 on the periodic table?

• Alkali metals

• Halogens

• Alkali Earth Metals

• Metalloids

Multiple Choice

As you move down the group, halogens' reactivity...

• increases

• decreases

• doesn't change

Multiple Choice

A displacement reaction involves...

• a solution turning brown or yellow.

• a less reactive element taking the place of a more reactive element.

• a more reactive element taking the place of a less reactive element.

Group 0 contains non-metal elements placed in the vertical column on the far right of the periodic table. The elements in group 0 are called the noble gases.

Group 0 Elements

• boiling point increases going down the group.

• density increases going down the group.

• atoms of group 0 elements have complete outer shells, so they are unreactive.

Properties

Multiple Choice

How many electrons are in the outer shell of the Group 0 elements?

• Full shell of electrons

• 8 electrons

• 0 electrons

• 7 elements

Multiple Choice

Why are the Group 0 elements unreactive?

• Their outer shell is empty

• Their outer shell is half full

• Their outer shell is full
