Does hydrogen belong to Group 7?
Does hydrogen belong to Group 7?
Hydrogen is a nonmetal and is placed above group in the periodic table because it has ns1 electron configuration like the alkali metals. However, it varies greatly from the alkali metals as it forms cations (H+) more reluctantly than the other alkali metals. Hydrogen also forms H2 dihydrogen like halogens.
Is hydrogen in a special group?
In brief explanation, Hydrogen is a nonmetal and is placed above group in the periodic table because it has ns1 electron configuration like the alkali metals. However, it varies greatly from the alkali metals as it forms cations (H+) more reluctantly than the other alkalimetals. …
What group is hydrogen part of?
Alkali Metals
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.
What group does hydrogen belong?
group 1
“Hydrogen is formally a member of group 1, but its chemis- try is usually dealt with separately from the other elements” (9). The typical periodic table in textbooks and in the usual chemistry classrooms charts (10) places hydrogen above the alkali metals.
What two groups can hydrogen be in?
Electronically, or by valence, hydrogen belongs in both groups I and VII. Its electronegativity, however, corre- sponds to a chemistry intermediate between the two ex- tremes. Hydrogen is, therefore, placed above the other elements and just to the left of carbon (1a).
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. …

Is hydrogen a part of group 1?
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.
In which group should hydrogen be placed in group 1 or Group 17 Why?
The reason why the hydrogen can be placed in both group 1 and group 17 is that it resembles Alkali metals in some of its properties like it can easily form cations so, it can be placed in Group 1 of periodic table but it also resembles Halogens in its properties like it forms which is true property of halogen that is …

What is the name of the element hydrogen?
Name: hydrogen. Symbol: H. Atomic number: 1. Relative atomic mass (A r): 1.008 range: [1.00784, 1.00811] m [see notes g m r] Standard state: gas at 298 K. Appearance: colourless. Classification: Non-metallic. Group in periodic table: 1.
Where does hydrogen go in the periodic table?
Hydrogen in Periodic table. Hydrogen element is in group 1 and period 1 of the Periodic table. Hydrogen is placed along with the alkali metals group as it has the similar outer electron configuration as that of the group 1 elements (i.e ns1). H.
Where can hydrogen be found in the atmosphere?
On Earth, hydrogen is found in the greatest quantities as water. It is present as a gas in the atmosphere only in tiny amounts – less than 1 part per million by volume.
What kind of compounds does hydrogen form in the body?
Hydrogen forms a vast array of compounds with carbon called the hydrocarbons, and an even vaster array with heteroatoms that, because of their general association with living things, are called organic compounds. The study of their properties is known as organic chemistry and their study in the context of living organisms is known as biochemistry.
