What are the characteristics of metals in the periodic table?

Back

Metals are typically shiny, malleable, ductile, and good conductors of heat and electricity.

Back

Metals tend to lose electrons and form positive ions, while nonmetals tend to gain electrons and form negative ions.

Front

What is the significance of the periodic table's arrangement?

Back

Elements are arranged by increasing atomic number, which reflects their electron configuration and chemical properties.

Front

What are metalloids?

Back

Elements that have properties of both metals and nonmetals, found along the zig-zag line on the periodic table.

Front

What is the role of electrons in chemical bonding?

Back

Electrons in the outer shell (valence electrons) are involved in forming bonds between atoms.

Front

What is the difference between an element and a compound?

Back

An element is a pure substance made of one type of atom, while a compound is made of two or more different types of atoms chemically bonded together.

Front

What is the general trend of reactivity in alkali metals?

Back
