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 are the characteristics of transition metals?

Back

Transition metals are typically good conductors of electricity and heat, have high melting and boiling points, and can form various oxidation states.

Front

What is the significance of valence electrons in determining an element's reactivity?

Back

Valence electrons determine how an element will bond with others and its overall reactivity.

Front

What is the periodic trend for atomic radius as you move across a period?

Back

Atomic radius decreases as you move from left to right across a period.

Front

What is the periodic trend for electronegativity as you move down a group?

Back

Electronegativity decreases as you move down a group.
