Periodic Table Test

Front

What is a transition metal?

Back

Transition metals are elements found in groups 3-12 of the periodic table, characterized by their ability to form variable oxidation states and colored compounds. Example: Iron (Fe) is a transition metal.

What is the chemical symbol for Carbon?

Back

C

Front

Which element is a period 1 element used to make balloons float?

Back

Helium (He)

Front

Identify the element in period 4, group 2 of the periodic table.

Back

Calcium (Ca)

Front

How do you calculate the atomic weight/mass of an atom?

Back

Atomic weight/mass = Number of protons + Number of neutrons. Example: For an atom with 11 protons and 10 neutrons, the atomic mass is 21.

Front

What are the main groups of the periodic table?

Back

The main groups include: Group 1 (Alkali metals), Group 2 (Alkaline earth metals), Group 17 (Halogens), and Group 18 (Noble gases).

Front

What is the significance of the atomic number?

Back

The atomic number is the number of protons in an atom's nucleus and determines the element's identity.

Front

What are noble gases?

Back

Noble gases are elements in group 18 of the periodic table, known for their lack of reactivity due to having a full valence shell. Examples: Helium (He), Neon (Ne).

Front

What is an isotope?

Back

Isotopes are variants of a chemical element that have the same number of protons but different numbers of neutrons. Example: Carbon-12 and Carbon-14.

Front

What is the difference between metals and nonmetals?

Back

Metals are typically shiny, conductive, and malleable, while nonmetals are dull, insulative, and brittle. Example: Iron (metal) vs. Sulfur (nonmetal).
