Atoms and the Periodic Table Study Guide

What kind of charge do protons have?

Explain the physical properties of alkaline earth metals and how they differ from alkali metals.

• Alkaline earth metals are softer and less reactive than alkali metals.

• Alkaline earth metals are shiny, ductile, and malleable, while alkali metals are dull and brittle.

• Alkaline earth metals are shiny and malleable, whereas alkali metals are soft and highly reactive.

• Alkaline earth metals are more reactive than alkali metals and are found in Group 1.

How are elements arranged on the periodic table?

Which group of the periodic table do alkali metals belong to?

• Group 1

• Group 2

• Group 3

• Group 4

In an atom, how many electrons can the first electron shell hold?

What is the maximum number of electrons that can be accommodated in the second energy level of an atom?

• 2

• 8

• 18

• 32

What do the elements in a Group on the periodic table have in common?

• the number of protons

• the number of electrons

• the number of neutrons

What is the primary purpose of an Electron Dot Diagram?

• To represent the total number of protons in an atom

• To illustrate the arrangement of isotopes in an element

• To show the outer energy level electrons of an atom

• To depict the mass number of an atom

What is the charge of a neutron?

• Neutrons have a neutral charge.

• A neutron's charge depends on the atom in which it is found.

• Neutrons have a positive charge.

• Neutrons have a negative charge.

An electron has a charge of:

• +1

• zero

• -1

• -2
