No element is a member of both the halogens and the alkali metals. Hydrogen shares some properties of the two groups, but belongs to neither. It is instead in a group all its own.

Why do halogens form compounds with alkali metals?
Because halogens form negative ions, alkali metals form positive ions; both are reactive elements and an electrostatic attraction exist.
Can Hydrogen make bond with alkali metals?
No, hydrogen is a nonmetal. It is grouped with the alkali metals because it has a similar outer shell electron configuration as they do. Hydrogen is something of an oddball among elements. It is rather unique, but share some characteristics with both the halogens and the alkali metals. When the periodic table is divided into groups (noble gasses, halogens, alkali metals, etc.) hydrogen is usually put in its own group.
Why is the position of hydrogen not justified in periodic table?
Because hydrogen resembles both Halogens and Alkali Metals.
Is fluorine an alkali metal or halogen?
No single element can be both an alkali metal (form +1 cations) and a halogen (form -1 anions).Alkali metals :LithiumSodiumPotassiumRubidiumCesiumFranciumHalogens:FluorineChlorineBromineIodineAstatine
What do alkali metals react vigorously with?
An alkali metal is any Group 1 metallic elements: lithium, sodium, potassium, rubidium, cesium and francium; all are strongly reative, soft low density metals. Which means if they come in contact with a halogen it can cause a vigorous reaction.
Why do halogens form compounds with alkali metals?
Because halogens form negative ions, alkali metals form positive ions; both are reactive elements and an electrostatic attraction exist.
What are the Group 1A and Group 7A elements examples of?
Sodium and Chlorine = Sodium Chloride Potassium and Iodine = Potassium Iodide
Classes of elements?
Metals, non metals and metaloids (which have some of the properties of both metals and non metals).
Can Hydrogen make bond with alkali metals?
No, hydrogen is a nonmetal. It is grouped with the alkali metals because it has a similar outer shell electron configuration as they do. Hydrogen is something of an oddball among elements. It is rather unique, but share some characteristics with both the halogens and the alkali metals. When the periodic table is divided into groups (noble gasses, halogens, alkali metals, etc.) hydrogen is usually put in its own group.
Which group of metals do halogens usually bond with offer an explanation?
For example halogens easily react with alkali metals because both are very reactive; compounds are with ionic bonds.
Why is the position of hydrogen not justified in periodic table?
Because hydrogen resembles both Halogens and Alkali Metals.
Why do elements in th alkali metals group often form iconic bonds with the halogen group?
Alkali metals have one electron in their valency shell whereas halogens have seven. By losing al electron to a halogen, both ions get a full set of electrons in their valency shell.
Is fluorine an alkali metal or halogen?
No single element can be both an alkali metal (form +1 cations) and a halogen (form -1 anions).Alkali metals :LithiumSodiumPotassiumRubidiumCesiumFranciumHalogens:FluorineChlorineBromineIodineAstatine

An alkali metal is any Group 1 metallic elements: lithium, sodium, potassium, rubidium, cesium and francium; all are strongly reative, soft low density metals. Which means if they come in contact with a halogen it can cause a vigorous reaction.
What is the most reactive metals that are found in a group?
Both the alkali metals and halogens because they only need one electron, or only need to lose 1 electron
Why is the position of hydrogen not fixed in the activity series?
Hydrogen shows the properties of both 1st and 7th groups:Resemblance Of Hydrogen With Alkali Metals(Group I-A)Like alkali metals hydrogen has one electron in its valency shell.ExplanationH (Z=1): K1Li (Z=3): K2, L1Na (Z=11): K2, L8, M1(2) Valance shell electronic configuration of hydrogen and alkali metal is same.ExplanationH (Z=1): 1S1Na (Z=11): 1S2,2S2,2P6,3S13) Both hydrogen an alkali metals are good reducing agents.4) Like alkali metals hydrogen can also form halides.Explanation: Hydrogen has capability to form Cation and least electronegative than halogens. For example:Hydrogen: HCl, HI.I-A: NaCl, KBr.Resemblance with Halogens:Both Hydrogen and Halogens require one electron to complete their valence shell.Both hydrogen and Halogens are non-metals (Except iodine which has partial metallic character).Both hydrogen and Halogens acts as negative ions when combined with metals.Their molecules are diatomic.Like Halogens, hydrogen can also form both ionic and covalent bond. Explanation: Hydrogen is least metallic as compared to other 1st group metals. For example:Hydrogen: NaH (ionic), CH4 (Covalent)Halogens: NaCl (ionic), HClHydrogen can receive maximum one electron to complete its octet to form anion and get give oneelectron only to form cation. Therefore cannot be fixed in single group.
What are the characteristics of semi-metals?
Metalloids are often dull, brittle, varying reactivity compared to halogens, alkali metals, alkali earth metals, and noble gases, can be liquid ( i.e mercury is a metalloid), naturally occurring, and others.
