Question 1: The diagram of an atom below shows two regions, the nucleus (1) and the area surrounding the nucleus (2). How are the protons, neutrons, and electrons that make up an atom distributed?

• Protons and neutrons in region 1, electrons orbiting in region 2
• Protons and electrons in region 1, neutrons orbiting in region 2
• Electrons and neutrons in region 1, protons orbiting in region 2
• Protons in region 1, neutrons and electrons orbiting in region 2

Question 2:The diagram shows a simplified version of the periodic table along with two arrows indicating down and across (left to right). The diagram shows a simplified version of the periodic table along with two arrows indicating down and across (left to right).

• Down = increases, Across = increases
• Down = decreases, Across = decreases
• Down = decreases, Across = increases
• Down = increases, Across = decreases

Question 3: An atom will be neutral if which of the following are true of its arrangement of subatomic particles?

• The number of its protons is equal to the number of its electrons.
• All of its electrons orbit its nucleus at exactly the same distance.
• The sum of the atom’s protons and neutrons is greater than zero.
• The nucleus of the atom contains more neutrons than anything else.

Question 4: A portion of the periodic table of elements is reproduced here. Based on their relative positions, what conclusions can be drawn about these metallic elements?

• All the elements have the same reactivity.
• Potassium is much more reactive than iron.
• Chromium is twice as reactive as vanadium.
• Calcium is much less reactive than scandium.

Question 5: A section of the periodic table is provided here. Which of the following statements best describes the electronegativity of the elements shown?

• Silicon has the lowest electronegativity.
• Selenium has a lower electronegativity than fluorine.
• Gallium has a higher electronegativity than carbon.
• Chlorine has the highest electronegativity.
