PS1.5 Chemical and Physical Properties Study Guide

Conductivity (the ability to transfer heat and electricity) is most closely associated with which group of elements?

• Non Metals

• Metals

• Metalloids

How do we find the number of valence electrons that an atom has?

• Look at the atomic number.

• It is the same as the number of protons.

• Subtract the atomic number from the atomic mass.

• Look at the group number for that element.

Families on the periodic table are grouped by their....

• Atomic Number.

• How different their properties are.

• How similar their properties are.

• How they look.

Which of the following is not a physical property?

• Color

• State of Matter (Solid, Liquid, or Gas) at room temperature

• Density of the sample

• If it reacts with water.

Looking at the periodic table, which family is least likely to be conductive?

• 17

• 4

• 1

• 2

Which property can we determine by using water displacement?

• Density

• Ductibility

• Conductivity

• State of Matter

What is special about group 18 (Noble Gases)?

• They react freely with most other elements.

• They are inert (non-reactive).

• They are conductive.

• The Noble Gases only react with metals.

How many valence electrons do the Alkali Metals (Family 1) have?

• 1

• 2

• 10

• 8
