Final answer:
The elements are Hydrogen, Phosphorus, Helium, Sulfur, Lithium, Chlorine, and Beryllium. Alkaline earth metals are named for their basic solutions when dissolved in water and have two electrons in their outer shell.
Step-by-step explanation:
The elements listed are:
Hydrogen (H)
Phosphorus (P)
Helium (He)
Sulfur (S)
Lithium (Li)
Chlorine (Cl)
Beryllium (Be)
Alkaline earth metals are named for their basic solutions when dissolved in water and have two electrons in their outer shell. Noble gases are unreactive due to a full valence shell and are gaseous at room temperature. Trace elements like boron, chromium, and zinc are essential for life in small amounts.
The term alkaline earth metals refers to the group of elements in Group 2 of the periodic table. These elements, which include beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra), are called alkaline because they form basic, or alkaline solutions when they react with water. The solutions have a pH greater than 7. One distinctive feature of these metals is that they all have two electrons in their outermost electron shell.
The noble gases comprise the Group 18 elements which include helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn). These elements are characterized by their lack of reactivity due to having a full valence shell of electrons. At room temperature, noble gases are in a gaseous state.
When it comes to the artwork titled "The Four Elements", it is a piece created by Frankie Fouganthin in 1961 using sheet metal and paint. While this information might be relevant for arts or history, it does not relate directly to the chemistry of elements.
There are almost 120 known elements on the periodic table, and the majority of these are metals. Among the nonmetals are elements like carbon (C), hydrogen (H), and oxygen (O). Additionally, there are trace elements which are essential for life in small amounts, including boron (B), chromium (Cr), and zinc (Zn).
