NAMING

Agenda

Review types of elements

Beginning naming rules

What are the three types of elements?

Metal

Nonmetal

Metalloid

Where are the metals?

On the Left

The Blue Ones

Where are the Nonmetals?

On the Right

The Red Ones

Where are the metalloids?

The Purple Ones

Monatomic Naming

Date:

Cations

Pawsitively charged ionsHave more protons than electrons

Rule for naming:Name the metalAdd the word “ion”

List the alkali metals

Hydrogen, H

Lithium, Li

Sodium, Na

Potassium, K

Hydrogen ion, H+

Lithium ion, Li+

Sodium ion, Na+

Potassium ion, K+

List the alkaline earth metals

Beryllium, Be

Magnesium, Mg

Calcium, Ca

Strontium, Sr

Barium, Ba

Beryllium ion, Be+2

Magnesium ion, Mg+2

Calcium ion, Ca+2

Strontium ion, Sr+2

Barium ion, Ba+2

List the Boron Family

Aluminum, Al

Gallium, Ga

Aluminum ion, Al+3

Gallium ion, Ga+3

Transition Metal Cations

Transition metals have variable charges; they can lose different numbers of electrons.All transition metals, tin and lead Except not Ag+, Cd+2, Zn+2

Rule for naming: Name the metal Tell the charge using Roman Numerals Add the word “ion”

Using orbital diagram to explain

Roman Numerals
