Hydrogen is a unique elemnt, it sadd an electron to form the hydride anion in which case it behaves like a halogen. It can lose an electron - get a naked proton, which rapidly attaches to anything in the vicinity, hence formation of acids in aqueous solution when say hydrogen chloride dissolves in water. It also forms single covalent bonds as in hydrogen chloride and methane and many other compounds. So similar to group1, in electron loss but forms covalent bonds group 1 do not in general. Gains an electron like a halogen but these hydrides are reactive and decompose in water.
Hydrogen in group 1 is classified as an alkali metal, while hydrogen in group 17 is classified as a halogen. Both hydrogen atoms contain only one electron in their outer shell. However, hydrogen in group 1 tends to lose this electron to form a cation, while hydrogen in group 17 tends to gain one electron to form an anion.

Why Hydrogen is it in its own group?
Hydrogen is in its own group because it shares similarities with both alkali metals and halogens, but doesn't fit perfectly into either group. It is unique in that it can gain or lose an electron, making it more like a nonmetal than a metal. This versatility allows hydrogen to form a wide range of compounds with other elements.
What element has the lower atomic number of any group?
Lithium is the element with the lowest atomic number in Group 1 (alkali metals), while hydrogen is the element with the lowest atomic number in Group 17 (halogens) and Group 18 (noble gases).
What two groups have elements that combine to form Sodium chloride?
The two groups are sodium (Na) from Group 1 and chlorine (Cl) from Group 17 of the periodic table. When sodium and chlorine combine, they form sodium chloride (NaCl), which is commonly known as table salt.
What group is chlorine in the periodic table?
Chlorine is in Group 17 of the Periodic Table.
Which element has characteristics most similar to fluorine?
Chlorine has characteristics most similar to fluorine because they are both in the same group (group 17) of the periodic table. They have similar chemical properties such as high electronegativity and reactivity.
What is the difference between hydrogen 16 and hydrogen 17?
1 more neutron
Why Hydrogen is it in its own group?

Where are hydrogen francium fluorine and bromine found in the periodic table?
Hydrogen is in the group 1.Francium is in the group 1 (alkali metals).Fluorine and bromine are in the group 17 (halogens).
Why does hydrogen act like a group 17 element when forming covalent bonds?
Hydrogen can act like a group 17 element (halogen) when forming covalent bonds because it has one electron in its valence shell, similar to elements in group 17. Hydrogen can share this electron to form a single covalent bond, like halogens, which also form single covalent bonds by sharing one electron.
What are the groups of periodic table which participated in hydrogen bonding?
Group 15: nitrogen Group 16: oxygen Group 17: fluorine
What does hydrochloric acid mean in the periodic table?
Hydrochloric acid comprises of elements-hydrogen and chlorine. Hydrogen is placed above in group-1 and chlorine in group-17
Why can hydrogen be placed in either group 1 or 7 on the periodic table?
Hydrogen can be in both group 1 and group 7 due to it's valence shell. Hydrogen only needs 2 (or 0) electrons to be stable. Because it has 1 electron, it can either accept one (like a group 7 element) or give one away (like a group 1 element). It can act like either group.
Explain whyIn Group 17 HF has abnormally high melting and boiling points as compared to other hydrides of the group?
Hydrogen bonding.
What is the only nonmetal in group 14?
Carbon (C)
Which group of elements reliably forms acids when combined with hydrogen?
Nonmetals typically form acids when combined with hydrogen. This includes elements such as sulfur, nitrogen, and chlorine. These elements tend to gain hydrogen ions (H+) to form acids when they react with hydrogen.
What unique element has similar properties to group 1 and 17?
Francium (Fr) has similar properties to both Group 1 (alkali metals) and Group 17 (halogens) elements. Due to its large size and single valence electron, francium shares some similarities with the alkali metals, while also having reactivity comparable to halogens due to the ease of losing its valence electron. Francium is highly reactive and is found in extremely low abundances in nature.
What is 17-alkyl group?
A 17-alkyl group refers to an alkyl group (a chain of carbon and hydrogen atoms) that is attached at the 17th position on a molecule, typically in organic chemistry. This modification can impact the molecule's properties, such as its stability, solubility, and biological activity.
