Phys Sci Benchmark 1 Review

According to the gas laws..... when the

temperature of a substance increases, what will

happen to the volume of the substance?

• The volume will decrease.

• The volume will stay the same.

• Not enough information given.

• The volume will increase.

An element exhibits the following characteristics:

● Brittle

● Lustrous

● Not ductile

● Mot malleable

● Conducts electricity only when cool

● Has an average transmission of heat.

What type of element is this?

• metal

• metalloid

• gas

• non-metal

Find Calcium (Ca, Atomic Number 20) on the

Periodic Table. How many Energy Levels does it

have compared to Carbon (C, Atomic Number

6)?

• The have the same number of Energy Levels.

• Calcium has 14 more Energy Levels than

  Carbon

• Calcium has 12 fewer Energy Levels than

  Carbon

• Calcium has 2 more Energy Levels than Carbon

The diagram shows a basic model of an atom.

Location X shows

• the neutron of an atom, which usually contains

  nuclei and electrons.

• the proton of an atom, which usually contains

  neutrons and electrons.

• the electron of an atom, which usually contains

  protons and neutrons.

• the nucleus of an atom, which usually contains

  protons and neutrons.

An element has 7 valence electrons. Predict how

that element would behave.

• The element is in group 7. It is highly reactive

  and has a charge of +7 because it loses 7

  electrons.

• The element is in group 7. It is not reactive and

  has a charge of -7 because it gains 7 electrons.

• The element is in group 7. It is not reactive and

  has a charge of +1 because it loses 1 electron.

• The element is in group 7. It is highly reactive

  and has a charge of -1 because it gains 1

  electron.

Which is the smallest part of an element that

retains all of the properties of the element?

• Proton

• Electron

• Neutron

• Atom

Find Calcium (Ca, Atomic Number 20) on the

Periodic Table. How many Energy Levels does it

• Calcium has 14 more Energy Levels than

  Carbon

• Calcium has 12 fewer Energy Levels than

  Carbon

• Calcium has 2 more Energy Levels than Carbon
