A. reactive B. stable C. inert D. non-reactive 相关知识点: 试题来源: 解析 A。原因:文中提到“the alkali metals in Group 1 are all very reactive and have one valence electron.”,即第一组的碱金属都非常活泼且有一个价电子。反馈 收藏 ...
- Group 1 Oxides: For example, Sodium oxide (Na2O) reacts with water to form Sodium hydroxide (NaOH), which is basic.- Group 2 Oxides: For example, Magnesium oxide (MgO) reacts with water to form Magnesium hydroxide (Mg(OH)2), which is also basic. Hint: Consider the nature of the...
Cotton chapter 10,11Group 1AGroup 1AQualitative alkali metal analysisAlkali MetalsThe group 1A elements with their ns1 valence electron configurations are very active metals. They lose their valence electrons very readily. They have low ionization energies and react with nonmetals to form ionic solids...
This is important because how elements interact and react with each other depends on their ability to lose and gain electrons to make new compounds. The horizontal rows of the table are called periods. Moving from the left side of the period to the right, the atomic radius becomes smaller be...

Vinyl sulfone reacts with thiol groups by a Michael addition reaction. Thiol selectivity and water stability are the main advantages of this reagent, which has been frequently used for pegylation of proteins using vinyl sulfone PEG derivatives [92]. View chapterExplore book Post-translational ...
Reactions of alkali metals with water All the Group 1 elements react with water to forme hydrogen gas and an alkaline solution. They are therefore known as alkali metals. The compound that is formed that causes the water to become alkaline is called a metal hydroxide. Generally: alkali metal ...
Except for cesium, which has a gold sheen, alkali metals are white. The alkali metals have one electron in their outer shell, and therefore react easily with other elements and are found in nature only in compounds. See Periodic Table. The American Heritage® Student Science Dictionary, ...
