The Periodic Table - Review Flashcard 2 test

Front

Which halogen is a liquid at STP?

Back

Br₂ (Bromine) is the only halogen that is a liquid at standard temperature and pressure.

Front

What is the element in Period 2 with the largest atomic radius?

Back

The element in Period 2 with the largest atomic radius is an alkali metal, specifically Lithium (Li).

Front

As you move down Group 15, what sequence in properties occurs?

Back

The sequence in properties as you move down Group 15 is nonmetal ⟶ metalloid ⟶ metal.

Front

How do nonmetals compare to metals in terms of electronegativity and ionization energy?

Back

Nonmetals generally have higher electronegativities and higher ionization energies compared to metals.

Front

Which group of elements in the Periodic Table contains a semimetal (metalloid)?

Back

Group 13 contains a semimetal (metalloid), specifically Boron (B).

Front

What is the general trend of atomic radius in the periodic table?

Back

Atomic radius increases as you move down a group and decreases as you move across a period from left to right.

Front

What are the characteristics of alkali metals?

Back

Alkali metals are highly reactive, have one electron in their outermost shell, and are soft and shiny.

Front

What defines a halogen?

Back

Halogens are a group of elements in Group 17 of the periodic table, known for their reactivity and tendency to form salts.

Front

What is the significance of noble gases in the periodic table?

Back

Noble gases are in Group 18 and are characterized by their lack of reactivity due to having a full valence shell.

Front

What is a metalloid?

Back

Metalloids are elements that have properties of both metals and nonmetals, and they are found along the zig-zag line in the periodic table.
