Group 3A elements are the alkaline earth metals. 27. Group 7A elements are highly reactive. metals. nonmetals noble gases true. Group 2A true metals.The elements in Group IIA (Be, Mg, Ca, Sr, Ba and Ra) are all metals, The term alkaline reflects the fact that many compounds of these metals are basic. 26. Group 3A elements are the alkaline earth metals. true. 27. Group 7A elements are highly reactive nonmetals known as halogens. false, noble gases.The group 3A elements are all metals. II Alkaline earth metals react less vigorously with water than do the alkali metals. III. Salts can consist of hydrogen.These elements (except hydrogen) are known as alkali metals, and they all have similar chemical properties. The elements in group 2 (the second column) form.
group 3 elements properties
There are 4 elements in Group 3Scandium, Yttrium, Lanthanum and Actinium. They are all metals, solid at room temperature and have the other physical properties. They are characterized as a group by having three electrons in the outermost parts of their atomic structure. Boron, the lightest of these elements, The densities of all the elements in Group 3 are higher than those in Group 2. The ionic radii of the elements are much smaller than the atomic radii, as three. Group 3 elements are generally hard metals with low aqueous solubility, and have low availability to the biosphere. No group 3 has any. The observed trends in the properties of the group 3 elements are similar to those of groups 1 and 2. Due to their ns2(n ? 1)d1 valence.
