Periodic Table of Elements and Molecules

Describe an atom and what are the parts of an atom.

composed of subatomic particles: protons, neutrons, and electrons. Broken into the Nucleus and Electron Cloud

What are the charges and locations of protons, neutrons, and electrons?

Nucleus (Protons = Positive, Neutrons = Neutral), Electron Cloud (Electrons = Negative )

Neon - Bohr Model

P= 10

N= 10

E= 10

VE= 8

Magnesium- Bohr Model

P= 12

N= 12

E= 12

VE= 2

Description of Bohr Models.

The nucleus which contains protons and neutrons surrounded by the electron cloud containing the electrons and their energy level.

What does the atomic number indicate?

The number of protons.

What are the number of neutrons in Sulfur, Carbon, Nitrogen, Helium, and Aluminum?

16,6,7,2,14

How is the Periodic Table is organised?

Increasing atomic number and groups and rows.

What is a group of the Periodic Table?

Are the columns of The Periodic Table within the groups the elements hold similar characteristics and have same number of valance electrons.

What is a period of the Periodic Table?

Are the rows of the Periodic Table; also indicates the energy level.

What are three of the chemical and physical properties of metals?

Usually solid at room temp, shiny, dense, melt at a high temperature, few valance electrons, ductile, and malleable.

What are the names of the following groups? Group 1, Group 2, Group 3-12, Group 17, Group 18?

Alkali Metals, Alkaline Earth Metals, Transition Metals, Halogens, Noble Gases.

Which group of metals contains the most reactive metals?

Alkali Metals

What are three chemical and physical characteristics of nonmetals?

Dull, low density, melt at a low temperature, usually a gas at room temperature, brittle, poor conductors of heat and electricity.

Which is the most reactive group of nonmetals?

Halogens

What is the most stable group of nonmetals?

Noble Gases

What are three chemical and physical characteristics of metalloids?

Properties of both Metals and non metals, can be shiny or dull, ductile, malleable, semiconductors.

Why is an atoms charge zero?

It is zero because the number of protons and electrons are the same, protons are positive; electrons are negative therefore if you had 1 proton their would be 1 negative electron would be zero and neutral.

What is the number of valence electrons for the following elements Nitrogen, Oxygen, Phosphorus, Carbon, Sodium, Argon?

5,6,5,4,1,8

What does it mean for something to be Ductile or Malleable?

Ductile means stretched into thin wires

Malleable means pounded into thin sheets without breaking.

How many groups and how many periods are on the Periodic Table?

Group 18 and Periods 7

What are elements 57-71 called?

Lanthanides

What are elements 89-103 called?

Actinides

How many valance electrons are in Group 1, Group 13, Group 15, Group 17, Group 18?

1,3,5,7,8

What are the rules for valance electrons if an atom has 1-3 VE, 4 VE, 5-7 VE, or 8 VE?

1-3 will lose the electrons, 4 will gain/lose, 5-7 will gain, 8 will not gain or lose.
