Why does hydrogen resemble both group 1 and group 17 elements?

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 do hydrogen and group 1 elements have in common?

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. Because it has two valence electrons like all the other elements in group 1.

What are the similarities of hydrogen with group 17?

Following are the similarities between hydrogen and halogens: (a) In both cases, one electron is required to complete its valence shell. (b) Hydrogen, as well as halogen, are non-metals. (c) When they are combined with metals, they act as negative ions.

Why can hydrogen be placed in group 1 or 17?

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.

Which group of elements does hydrogen resemble and how does it resemble them?

Hydrogen resembles both, alkali metals as well as halogens.

How is hydrogen similar to the elements below it how is it different from them?

How is hydrogen similar to the elements below it? How is it different from them? Hydrogen is similar to the Alkali family because they all have 1 valence electron. They are different because hydrogen is a gas and is a non-metal, and every element in the Alkali family is a solid and metal.

What are the properties of hydrogen?

Hydrogen is a colorless, odorless, tasteless, and nonpoisonous gas under normal conditions on Earth. It typically exists as a diatomic molecule, meaning each molecule has two atoms of hydrogen; this is why pure hydrogen is commonly expressed as “H2“.

What do you think should hydrogen be placed in group 17 of halogen or Group 1 of alkali metals in the modern periodic table?

Hydrogen’s atomic number is 1,hence there is only 1 electron in outermost shell. So to be stable Hydrogen loses its electron and makes 1 positive charge. Therefore, instead keeping Hydrogen in group of halogens it should be in group 1st that is alkali metals group.

Why hydrogen can resemble the Group 1A and the Group 7A elements?

Sometimes hydrogen lose the one electron from their subshell like alkali metal and form 1s0(nS0) electronic configuration. This electronic configuration of hydrogen resembles to 1A. Depending on the electronic configuration hydrogen can resemble the Group 1A and the Group 7A elements.

How do hydrogen and alkali metals resemble?

(i) Resemble with alkali metals : It has one valence electron in s-orbital like alkali metals. It can lose one electron to form H+ ion like alkali metals. It is a strong reducing agent like other alkali metals.

Why is hydrogen not a group 1 metal?

In fact, the chemistry of hydrogen does not greatly resemble that of the metals of Group 1. Indeed, some versions of the periodic table place hydrogen above fluorine in Group 17 because the addition of a single electron to a hydrogen atom completes its valence shell.

Does hydrogen have a group 1 electron configuration?

Although hydrogen has an ns 1 electron configuration, its chemistry does not resemble that of the Group 1 metals. Hydrogen, the most abundant element in the universe, is the ultimate source of all other elements by the process of nuclear fusion.

How does hydhydrogen resemble halogens in the periodic table?

Hydrogen resemble halogens i. F , Cl, Br , I of group 17 of the periodic table in the following ways: 1) Electronic configuration: All the halogens have 7 electron in their respective outermost shell and thus have one electron less than the stable configuration of the nearest inert gas.

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.
