Periodic Table (IC)

Front

What is the atomic number of an element?

Back

The atomic number tells you the number of protons in the atom of the nucleus.

Front

Which group of elements is known for having similar properties and is found in the same column of the periodic table?

Back

Groups or families of elements.

Front

What are transition metals?

Back

Transition metals are elements found in the d-block of the periodic table, known for their ability to form variable oxidation states and colored compounds.

Front

How does the reactivity of alkali metals change down the group?

Back

The reactivity of alkali metals increases as you move down the group.

Front

What is the trend in atomic radius across a period?

Back

The atomic radius decreases from left to right across a period due to increased nuclear charge.

Front

Which element has a larger atomic radius: Sodium (Na) or Potassium (K)?

Back

Potassium (K) has a larger atomic radius than Sodium (Na).

Front

What is the significance of the periodic table's arrangement?

Back

The periodic table is arranged by increasing atomic number, which reflects the periodicity of element properties.

Front

What is the general trend of ionization energy across a period?

Back

Ionization energy generally increases across a period.

Front

What is the difference between metals and nonmetals in the periodic table?

Back

Metals are typically good conductors of heat and electricity, while nonmetals are poor conductors.

Front

What is the relationship between energy levels and the period number in the periodic table?

Back

The period number indicates the number of energy levels or shells an atom has.
