Periodic Classification of Elements - Lesson Quiz 1

What is the basis for the modern periodic table?

• Atomic mass

• Atomic number

• Number of neutrons

• Number of electrons

Which of the following is the correct order of elements in a period?

• Increasing atomic mass

• Increasing atomic number

• Decreasing atomic mass

• Decreasing atomic number

Elements in the same group of the periodic table share similar

• Atomic mass

• Atomic number

• Chemical properties

• Physical properties

As you move down a group in the periodic table, the atomic radius generally

• Increases

• Decreases

• Remains constant

• Varies unpredictably

Which of the following elements has the highest electronegativity?

• Cesium (Cs)

• Fluorine (F)

• Sodium (Na)

• Oxygen (O)

Which of the following elements is a metalloid?

• Carbon (C)

• Silicon (Si)

• Sodium (Na)

• Oxygen (O)

Noble gases are generally

• Highly Reactive

• Highly Unreactive

• Good Conductors of Electricity

• Malleable and Ductile

Elements in group 1 are known as

• Halogens

• Alkali Metals

• Alkaline Earth Metals

• Noble Gases

The number of valence electrons in an element is equal to its

• Group Number

• Period Number

• Atomic Mass

• Atomic Number

The periodic table can be used to predict

• The number of neutrons in an atom.

• The chemical properties of an element.

• The physical state of an element at room temperature.

• All of the above.
