Why is hydrogen placed with the group 1 elements How is it different from the other group 1 elements?

Why is hydrogen placed with the group 1 elements How is it different from the other group 1 elements?

Hydrogen 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 has a much smaller electron affinity than the halogens.

Why is hydrogen so different from other elements?

Hydrogen is the smallest chemical element because it consists of only one proton in its nucleus. Hydrogen has one one proton and one electron; the most common isotope, protium (1H), has no neutrons. Hydrogen has a melting point of -259.14 °C and a boiling point of -252.87 °C.

How is hydrogen different from alkali metals?

Hydrogen is a very reactive gas, and the alkali metals are even more reactive. In fact, they are the most reactive metals and, along with the elements in group 17, are the most reactive of all elements.

How are the elements in group 1 different?

All the Group 1 elements are very reactive . They must be stored under oil to keep air and water away from them. Group 1 elements form alkaline solutions when they react with water, which is why they are called alkali metals.

Why is hydrogen not placed in any group?

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.

Why hydrogen can be placed in group 1 and 17?

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 …

Is hydrogen a Group 1 element?

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 is the uniqueness of hydrogen?

Hydrogen is unique because it does not have any neutrons. Hydrogen’s nucleus only contains a proton. This is the only element to lack neutrons. …

Is hydrogen a group 1 element?

Why is hydrogen in group 1 if it is not a metal?

Why is hydrogen not considered to be a member of Group 1 the alkali metals )?

there is variety of isotope of element found it is not possible to arrange in periodic table if they arranged on the basis of atomic mass. So due to isotope of hydrogen it is not placed on fixed place. in the periodic table of Mendeleev he placed it into alkali metal instead of placing it into halogens.
