why are alkali metals in group 1?
2078
The Group 1 elements are called the alkali metals. ... All the Group 1 elements are very reactive . They must be stored under oil to keep air and water away from them. Group 1 elements form alkaline solutions when they react with water, which is why they are called alkali metals.

The Group 2 alkaline earth metals include Beryllium, Magnesium, Calcium, Barium, Strontium and Radium and are soft, silver metals that are less metallic in character than the Group 1 Alkali Metals.

The alkali metals, found in group 1 of the periodic table, are highly reactive metals that do not occur freely in nature. ... As with all metals, the alkali metals are malleable, ductile, and are good conductors of heat and electricity. The alkali metals are softer than most other metals.

Group 1A (or IA) of the periodic table are the alkali metals: hydrogen (H), lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr). ... The name comes from the fact that when these metals or their oxides are dissolved in water, a basic (alkaline) solution results.

For groups 1-2 and 13-18, the valency is directly related to group number. So, elements in group one, the alkali metals, have one valence electron, those in group two have two valence, those in group thirteen have three electrons, and so on.

alkali metal: Has one electron in their outer shell and can be found in Group I in the periodic table.

Reactions with Group 1 Elements Group 1 metals are very reactive with oxygen and must be kept away from oxygen in order to not get oxidized. These alkali metals rapidly react with oxygen to produce several different ionic oxides.

Some of the groups have widely-used common names, including the alkali metals (Group 1) and the alkaline earth metals (Group 2) on the far left, and the halogens (Group 17) and the noble gases (Group 18) on the far right. The elements can be broadly divided into metals, nonmetals, and semimetals.

All the Group 1 elements - lithium (Li), sodium (Na), potassium (K), rubidium (Rb), caesium (Cs) and francium (Fr) - have one electron in the outer shell.

"Alkali metals are good oxidizing agents." ... Alkali metals are strong reducing agents. This is so because of the ease with which they lose electrons. The atoms do not have a strong attraction for the single valence electron, and so it is easily lost (small first ionisation energy) to from a +1 ion.

The s-metals consist of the Alkali Metals (Group 1) and the Alkaline Earth Metals (Group 2). ... Some of the Group 1 and 2 metals are amongst the most abundant: calcium, sodium, magnesium and potassium are the 5th to 8th most abundant metals respectively, though others like Lithium and Beryllium have very low abundances.

Group 1 - the alkali metals. The Group 1 elements in the periodic table are known as the alkali metals. They include lithium, sodium and potassium, which all react vigorously with water to produce an alkaline solution.
482604
In the periodic table, the alkali metals are a group or column containing the chemical elements such as lithium (Li), sodium (Na), rubidium (Rb), potassium (K), francium (Fr) and Caesium (Cs). ... All the alkali metals react with water, with the heavier alkali metals reacting more overwhelmingly than the lighter ones.
358295
The group 1 elements are all soft, reactive metals with low melting points. They react with water to produce an alkaline metal hydroxide solution and hydrogen. Reactivity increases down the group.
635472
Why are they called the alkali metals? The alkali metals are so named because when they react with water they form alkalies. Alkalies are hydroxide compounds of these elements, such as sodium hydroxide and potassium hydroxide. ... Alkalies react with acids to form salts.

For example, the elements of Group 1 are known as the alkali metals, Group 2 are the alkaline earth metals, Group 17 are the halogens, and Group 18 are the noble gases.
