Multiple Choice

Chlorine ( Cl) has _________ valence electrons.

• 8

​valence elctrons determne reactivity

​

​

Anything to do with reactivity, bonding, or reacting is caused/determined by Valence electrons.

An element wants to be stable

• Stable means a full outer shell of 8 electrons (except Helium which is "full" with only 2)

• Elements will add or lose electrons to have a full outershell

Some text here about the topic of discussion

Multiple Choice

What are valence electrons?

• The total number of electrons in an atom

• The number of electrons in the outermost shell

• The number of electrons in the second shell

• The number of protons in the outermost shell

Multiple Choice

All atoms are most stable with (or would "prefer") how many electrons in their valence shell?

• 1

• 2

• 8

• 18

Multiple Choice

When trying to identify an unknown element, a scientist determines what other elements reacts with chemically. Which property of the unknown element determines the other element it reacts with?

• The total number of neutrons in the unknown element

• The total number of particles in the nucleus of the unknown element

• The number of protons in the nucleus of the unknown element

• The number of valence electrons in the unknown element

Multiple Choice

Describe this element.

• Highly reactive metal
• Highly reactive nonmetal
• Stable
• Less stable non metal

Protons determine the identity of an element.

Each element has a unique number of protons and that number never changes for that element.​

Multiple Choice

The vertical (up and down) columns in the Periodic Table are called

• groups

• towers

• periods

• atomic numbers

Multiple Choice

The horizontal row on the periodic table is called a

• group

• period
• atomic number

Multiple Choice

Elements in a .................. have similar chemical properties.

• period

• group

• row

Multiple Choice

Find an element with similar chemical properties to Barium (Ba).

• Ca an Ra, because they are in the same group and have similar chemical properties.

• Cs and La, b/c they are in the same period number.

• Ca and Y, b/c they are 90 degree angle and have similiar properties.
