Elements with two electrons in their outermost shell belong to Group 2 of the periodic table, also known as the alkaline earth metals. Step 2: Identify the Elements1. Beryllium (Be): - Atomic number: 4 - Electron configuration: 1s² 2s² - In the outermost shell (2s), there are ...
Firstly, I belong to Group 2 of the periodic table, also known as the alkaline earth metals. This grouping signifies my reactivity with other elements, particularly my tendency to lose two electrons, forming a positive ion, Mg²⁺. My atomic number is 12, meaning I have 12 protons in ...
Name 6 of the first 12 elements that were isolated. Are most of these metals or nonmetals? List some of the first gaseous elements discovered. How did Humphrey Davy discover six new elements? Classify each element as an alkali metal, alkaline earth metal, halogen, or noble gas. a. sodium...
Sodium and potassium are abundant in Earth's crust, each comprising about 2.5 percent, and the two being the 6th and 7th most abundant elements, respectively. Other alkali metals are at least one hundred times less abundant. Francium is virtually nonexistent in the environment since all isotopes...
Alkaline earth metal PRONUNCIATION mag-NEE-zee-um Large amounts of magnesium are used to make alloys. An alloy is made by melting or mixing two or more metals. The mixture has properties different from those of the individual metals. Magnesium alloys are quite light, yet very strong. Th...
