Periodic Table

Front

What is the main characteristic of alkali metals?

Back

Alkali metals are highly reactive, especially with water, and have one electron in their outermost shell.

Front

Which element is an example of a halogen?

Back

Chlorine is an example of a halogen.

Front

What are noble gases known for?

Back

Noble gases are known for being inert and non-reactive due to having a full outer electron shell.

Front

What does the atomic number represent in the periodic table?

Back

The atomic number represents the number of protons in the nucleus of an atom.

Front

What is the significance of the atomic mass in the periodic table?

Back

The atomic mass indicates the average mass of an element's atoms, accounting for isotopes.

Front

Which group in the periodic table contains elements that are good conductors of electricity?

Back

The metals group contains elements that are good conductors of electricity.

Front

What is the periodic trend for reactivity in alkali metals?

Back

Reactivity increases as you move down the group in alkali metals.

Front

What is the common property of elements in the same group of the periodic table?

Back

Elements in the same group have similar chemical properties due to having the same number of valence electrons.

Front

What is the role of electrons in chemical bonding?

Back

Electrons, particularly valence electrons, are involved in forming chemical bonds between atoms.

Front

What distinguishes transition metals from other metals?

Back

Transition metals can form variable oxidation states and have incomplete d subshells.
