Front

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

Back

Elements with properties intermediate between metals and nonmetals, typically found along the zig-zag line.

Front

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

Back

It represents the number of protons in an atom's nucleus and determines the element's identity.

Front

What distinguishes nonmetals from metals in terms of physical properties?

Back

Nonmetals are generally poor conductors of heat and electricity, and they are not malleable or ductile.

Front

What is the general trend of reactivity among alkali metals?

Back

Reactivity increases as you move down the group in the periodic table.
