Front

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

Back

It determines the position of an element in the periodic table and its chemical properties.

Front

What are alkali metals?

Back

They are highly reactive metals found in Group 1 of the periodic table.

Front

What is the general trend in reactivity for alkali metals as you move down the group?

Back

Reactivity increases as you move down the group.

Front

What is a nonmetal?

Back

An element that typically lacks the properties of metals and can be a poor conductor of heat and electricity.
