Periodic Table and Trends

Front

What are metals generally characterized by in terms of physical state and melting/boiling points?

Back

Metals generally have high melting/boiling points and are almost all solids at room temperature.

Front

What is the primary characteristic of metals regarding their ability to conduct heat and electricity?

Back

Metals are good conductors of heat and electricity.

Front

How many valence electrons do alkaline earth metals have?

Back

Alkaline earth metals all have 2 valence electrons.

Front

Which element is the most electronegative in the 4th period of the periodic table?

Back

Bromine (Br) is the most electronegative element in the 4th period.

Front

Who is known as the 'Father of the Periodic Table'?

Back

Dmitri Mendeleev is considered the 'Father of the Periodic Table' for predicting the properties of undiscovered elements.

Front

What is the general trend of electronegativity across a period in the periodic table?

Back

Electronegativity generally increases across a period from left to right.

Front

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

Back

Atomic radius generally increases down a group in the periodic table.

Front

What are metalloids and where are they located on the periodic table?

Back

Metalloids have properties of both metals and nonmetals and are located along the zig-zag line on the periodic table.

Front

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

Back

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

Front

What is the difference between ionic and covalent bonding?

Back

Ionic bonding involves the transfer of electrons, while covalent bonding involves the sharing of electrons.
