2. Where are the alkali metals and the halogens located on the periodic table? The alkali metals are in Group1 and the halogens are in Group 7.

The halogens all have the general electron configuration ns2np5, giving them seven valence electrons. They are one electron short of having full outer s and p sublevels, which makes them very reactive. They undergo especially vigorous reactions with the reactive alkali metals.

Both group form ionic compound but only Halogens for covalent bonds. THe Alkali metals have low densities while the Halogens have high densities and the melting point and boiling point patterns are opposite for the Halogens it increases whereas for the Alkali metals it decreases.

The Group 1 elements are called the alkali metals. They are placed in the vertical column on the left-hand side of the periodic table . All the Group 1 elements are very reactive . They must be stored under oil to keep air and water away from them.
896666
The alkaline earth elements are metallic elements found in the second group of the periodic table. All alkaline earth elements have an oxidation number of +2, making them very reactive. Because of their reactivity, the alkaline metals are not found free in nature.

Group 1 – the alkali metals. The Group 1 elements are called the alkali metals. They are placed in the vertical column on the left-hand side of the periodic table . All the Group 1 elements are very reactive .
647379
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.

Because of their great reactivity, the free halogen elements are not found in nature. In combined form, fluorine is the most abundant of the halogens in Earth's crust. The percentages of the halogens in the igneous rocks of Earth's crust are 0.06 fluorine, 0.031 chlorine, 0.00016 bromine, and 0.00003 iodine.

The halogens are a series of non-metal elements from group 17 of the periodic table (formerly VII). The halogens include fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At). The artificially created element 117 (ununseptium) may also be considered a halogen.

Alkali metals are the first group in the periodic table. They are never found in nature uncombined because they are unstable and they react fast to other elements. They bond well with all elements except the noble gases.

The alkaline earth elements are metallic elements found in the second group of the periodic table. All alkaline earth elements have an oxidation number of +2, making them very reactive.

alkali metal: Has one electron in their outer shell and can be found in Group I in the periodic table.
312895
Alkali metals are the first group in the periodic table. They are never found in nature uncombined because they are unstable and they react fast to other elements. They bond well with all elements except the noble gases. When they are in air, they quickly turn black.

As you go down group 1 (the alkali metals) in the periodic table, the elements get more reactive. As you go up group 7 (the halogens), again the elements get more reactive.

The Brainliest Answer! The alkaline earth metals are six chemical elements in group 2 of the periodic table. They are beryllium(Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra).
528223
The alkali metals, found in group 1 of the periodic table (formerly known as group IA), are very reactive metals that do not occur freely in nature. These metals have only one electron in their outer shell. Therefore, they are ready to lose that one electron in ionic bonding with other elements.
