Answer: The transition elements are in the d-block, and in the d-orbital have valence electrons. They can form several states of oxidation and contain different ions. Inner transition elements are in the f-block, and in the f-orbital have valence electrons.
Explanation:
Alkali metals<span> include </span>lithium<span>, sodium, potassium, rubidium, cesium and francium. These </span>metals<span> have large atomic radii and generally lose electrons during reactions. They have relatively soft textures, which makes them easy to mold, shape and dissect for </span><span>various uses</span>
Valence electrons largely determine the chemical properties of an element.
