Periodic Table Review

Front

What is an alkali metal?

Back

Alkali metals are elements found in Group 1 of the periodic table, characterized by their high reactivity and the presence of one electron in their outermost shell. Example: Sodium (Na).

Front

Which group does Magnesium belong to?

Back

Magnesium is in Group 2 of the periodic table, known as the alkaline earth metals.

Front

What are metalloids?

Back

Metalloids are elements that have properties intermediate between metals and nonmetals. They are located along the staircase line on the periodic table.

Front

How many periods are in the periodic table?

Back

There are 7 periods in the periodic table.

Front

What is the significance of an element's group number?

Back

The group number indicates the number of valence electrons in the outer shell of the elements, which determines their chemical properties.

Front

Name two elements that have similar chemical properties to Barium (Ba).

Back

Calcium (Ca) and Radium (Ra) have similar chemical properties to Barium because they are in the same group (Group 2).

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. Example: Neon (Ne).

Front

What is the periodic trend for atomic size?

Back

Atomic size increases down a group and decreases across a period from left to right due to increasing nuclear charge.

Front

What is the difference between metals and nonmetals?

Back

Metals are typically shiny, good conductors of heat and electricity, and malleable, while nonmetals are usually dull, poor conductors, and brittle.

Front

What is the role of valence electrons in chemical bonding?

Back

Valence electrons are the outermost electrons of an atom and are involved in forming chemical bonds with other atoms.
