Does hydrogen belong to group 1 Why or why not?
Unlike the group one elements hydrogen is clearly not a metal (it is a gas at room temperature) and is a poor conductor of heat and electricity. It does not readily form H+ cations and forms covalent bonds in most compounds, whereas group 1 metals readily form cations and form only ionic bonds.
Which group does hydrogen belong to and why?
Group 1A — The Alkali 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). These are (except for hydrogen) soft, shiny, low-melting, highly reactive metals, which tarnish when exposed to air.
Why is hydrogen in group 1 and if hydrogen was placed in the group it really belongs where would it be?
Why is hydrogen, a nonmetal, placed in the same group as the alkali metals? Because it has eight valence electrons like all the other elements in group 1. Because it has just one valence electron like all the other elements in group 1.
Why does hydrogen fit into this group?
Hydrogen has been placed in Group 7A (IUPAC Group 17), because — just like elements in that group — it is monovalent in common compounds and requires just one electron to fill its outer shell.
Is hydrogen included in Group 1?
Alkali metals are the chemical elements found in Group 1 of the periodic table. Although often listed in Group 1 due to its electronic configuration, hydrogen is not technically an alkali metal since it rarely exhibits similar behavior. …
What 2 groups can hydrogen act like?
However, sometimes the groups are just labeled #1-18. Two at the Top: Hydrogen (H) and helium (He) are special elements. Hydrogen can have the talents and electrons of two groups, one and seven & sometime it is missing an electron, and sometimes it has an extra. Helium is different from all of the other elements.
What classification group does hydrogen belong?
Hydrogen, with its single electron, also lives in Group 1, but the gas is considered a nonmetal. Alkaline-earth metals: The alkaline-earth metals make up Group 2 of the periodic table, from beryllium (Be) through radium (Ra).

Which group is hydrogen in the periodic table?
What is the IUPAC group of hydrogen?
Hydrogen has been placed in Group 7A (IUPAC Group 17), because — just like elements in that group — it is monovalent in common compounds and requires just one electron to fill its outer shell. It’s also a non-metal that — as the pure element — forms single-bonded, diatomic molecules, just like every other element in Group 17.
What group does hydrogen belong to on the periodic table?
Hydrogen’s Placement in the Periodic Table. Because hydrogen forms compounds with oxidation numbers of both +1 and -1, many periodic tables include this element in both Group IA (with Li, Na, K, Rb, Cs, and Fr) and Group VIIA (with F, Cl, Br, I, and At).
Why is hydrogen included in the group IA?
There are many reasons for including hydrogen among the elements in Group IA. It forms compounds (such as HCl and HNO 3 ) that are analogs of alkali metal compounds (such as NaCl and KNO 3 ).
Why is hydhydrogen a group 1 element?
Hydrogen is a unique element in that it only has one outer, valence, electron with a maximum of two in its outer shell. Because of this hydrogen fits in group 1 because all group 1 elements have one valence electron and it also tends to favour forming a cation H+.
