Group 1: Properties of Alkali Metals - Chemistry LibreTexts
2023年6月30日 · This page discusses the trends in some atomic and physical properties of the Group 1 elements - lithium, sodium, potassium, rubidium and cesium. Sections below cover the trends in atomic radius, first ionization energy, electronegativity, melting and boiling points, and density. The chart below shows the increase in atomic radius down the group.
Alkali metal - Wikipedia
The alkali metals consist of the chemical elements lithium (Li), sodium (Na), potassium (K), [note 1] rubidium (Rb), caesium (Cs), [note 2] and francium (Fr). Together with hydrogen they constitute group 1, [note 3] which lies in the s-block of the periodic table.
Group 1 alkali metals Group 1 – the alkali metals - BBC
The Group 1 elements, also known as the alkali metals, all react vigorously with water to produce an alkaline solution. Part of Chemistry (Single Science) Atomic structure and the periodic...

The alkali metals are potent reductants whose chemistry is largely that of ionic compounds containing the M+ ion. Alkali metals have only a weak tendency to form complexes with simple Lewis bases. …
Alkali metal | Definition, Properties, & Facts | Britannica
alkali metal, any of the six chemical elements that make up Group 1 (Ia) of the periodic table —namely, lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr). The alkali metals are so called because reaction with water forms alkalies (i.e., strong bases capable of neutralizing acids).
Group 1 - Creative Chemistry
The group 1 elements are placed on the left of the periodic table. They are called the alkali metals because they are metals, and their oxides and hydroxides form alkaline solutions. In general, the alkali metals: are soft, and easily cut with a knife; have relatively low melting points compared to …

All are soft, lustrous, reactive metals with low melting points. Reactivity increases down the group as ionization energy decreases. Almost all compounds are ionic, except for some Li and Na organometallic compounds. Same charge and similar size of NH4 +, Ag+, and Tl+ result in similar compounds, often isomorphous with alkali metal analogs.
Group 1: Hydrogen and the Alkali Metals - Chemistry LibreTexts
2023年6月30日 · Alkali metals are the chemical elements found in Group 1 of the periodic table. The alkali metals include: lithium, sodium, potassium, rubidium, cesium, and francium. Although often listed in Group 1 due to its electronic configuration, hydrogen is not technically an alkali metal since it rarely exhibits similar behavior.
