group 2
period 5
Strontium is an alkaline earth metal; group 2 and period 5 in the periodic table of Mendeleev.
Strontium is Sr and has a valence of 2+ (group II). Nitrogen in N and has a valence of 3 (group XV). Thus, when they combine they make strontium nitride, which is Sr3N2.
Strontium is not an alkali metal; it is an alkaline earth metal. Alkali metals are Group 1 elements, such as lithium, sodium, and potassium, while alkaline earth metals are Group 2 elements, including strontium.
Strontium belongs to the group 2 elements in the periodic table, also known as the alkaline earth metals. It has chemical properties similar to other elements in this group, such as calcium and magnesium.
Strontium (Sr)
Strontium has 2 valence electrons because it is in Group 2 of the periodic table. The oxidation number of strontium is typically +2, as it tends to lose those 2 valence electrons to achieve a stable electronic configuration.
Another element in group 2 of the periodic table is strontium. It has an atomic number of 38 and is a soft, silvery metal that is similar in properties to calcium. Strontium is commonly used in fireworks and in the production of cathode ray tubes.
Strontium shares more properties with barium, as they are both members of Group 2 (alkaline earth metals) in the periodic table. These elements have similar chemical properties due to their position in the same group. Yttrium, on the other hand, belongs to a different group (Group 3) and therefore has different properties compared to strontium.
Strontium is classified as an alkaline earth metal. It belongs to group 2 on the periodic table and shares characteristics with other elements in this group, such as calcium and magnesium. It is a soft, silver-white metal that is highly reactive with water and air.
Strontium is not a metalloid; it is a metal. It belongs to the group 2 elements in the periodic table, also known as the alkaline earth metals. Metalloids have properties that are in between metals and nonmetals, whereas strontium displays typical metallic characteristics.
Strontium has 2 valence electrons. It is in group 2 of the periodic table, which means it has 2 electrons in its outermost energy level.
Group IIA: beryllium, magnesium, calcium, strontium, barium and radium.
