Atoms and the Periodic Table Review

Atoms and the Periodic Table Review

by Ms. Lewis

​Metals, Nonmetals, and Metalloids

• ​The periodic table can be divided based on whether the elements are metals, nonmetals, or metalloids.

• ​Metals are shiny, conduct heat and electricity, are malleable, and ductile.

• ​Non-metals are dull, do not conduct heat or electricity, and are brittle.

• ​Metalloids have various properties of metals and non-metals. They are "in between" metals and nonmetals.

​Understanding the Elements

• ​The Periodic Table of Elements tells us the atomic number, element symbol, element name, and the atomic weight/mass of an element.

• ​The atomic number matches the number of protons and electrons in an atom.

Multiple Choice

What is the atomic number of this elements atom?

• 4

• 2

• 3

• 6

Multiple Choice

What is the atomic mass of this elements atom?

• 4

• 2

• 3

• 6

Multiple Choice

What is the atomic number of this elements atom?

• 308

• 136

• 222

• 86

Multiple Choice

What is the atomic mass of this elements atom?

• 308

• 136

• 222

• 86

​Neutrons

• ​Located inside the nucleus

• ​Protons and Neutrons together make up the atomic mass.

• ​To find the number of protons, subtract the atomic number from the mass. What you have left is how many neutrons you have.

Multiple Choice

How many neutrons are in the nucleus of this elements atom?

• 4

• 2

• 3

• 6

Multiple Choice

How many neutrons are in the nucleus of this elements atom?

• 308

• 136

• 222

• 86

Multiple Choice

How many neutrons are in the nucleus of this elements atom?

• 64

• 29

• 35

• 34

​Bohr Model

• ​A model of an atom showing the number of electrons present.

• ​Ring 1, closest to the nucleus, can hold 2 electrons.

• ​Ring 2 can hold 8 electrons

• ​Ring 3 can hold up to 18 electrons

• ​Ring 4 can hold 32 electrons

Multiple Choice

Which of these is the correct Bohr model for Hydrogen (1)?

Multiple Choice

Which of these is the correct Bohr model for Flourine (9)?

Multiple Choice

Which of these is the correct Bohr model for Helium (2)?

Multiple Choice

Which of these is the correct Bohr model for Copper (29)?

​Valence Electrons

• ​The outermost shell of an atom is the valance shell.

• ​The electrons on the valence shell are called valence electrons.

• ​The fullness of the valance shell determines how reactive (happy or mad) an atom is.

​Lewis Dot Model

• ​One way we can display the reactivity of an atom is to use the Lewis Dot Model.

• ​Has the chemical symbol surrounded by dots to represent the valence electrons.
