How do you justify position of hydrogen at the top of various groups?

How do you justify position of hydrogen at the top of various groups?

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.

How do you justify the position of hydrogen?

The dual nature of hydrogen can be justified by following points:

1. As stated earlier, hydrogen like other alkali metal lose the only electron to form unipositive ion.
2. When hydrogen is present in compound state like HCl it exhibits +1 oxidation state like other alkali metals.

How can you justify the position of hydrogen in group first?

Hydrogen is the first element of the periodic table & often called protium. Its electronic configuration is [1s1]. Due to the presence of only one electron in its 1s shell, hydrogen exhibits a dual behaviour, i.e., it resembles both alkali metals and halogens.

Why is hydrogen placed on the left side of the periodic table at the top of the 1st group?

Because hydrogen has a single valence electron, it is grouped with other elements, such as lithium, that have only one valence electron. 6 The Alkali Metals The elements in Group 1A are called alkali metals. These metals have a single valence electron and are extremely reactive.

Where do you think should hydrogen be placed in the modern periodic table Class 10?

Answer: Hydrogen should be placed above the elements of group 1 because its electronic configuration is similar to the alkali metals and it can also be placed in group 17 because because its chemical properties found to be similar to (F, Cl, Br).

What is the position of hydrogen?

So if you glance at the periodic table, you will see hydrogen is the first element in the table. It is the smallest element on the table. It has atomic number one, which means it has only one electron orbiting it its shell. In fact, Hydrogen has only one shell.

What do you think should hydrogen be placed in the group 17 of halogens 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.

How is position of hydrogen justified in modern periodic table?

Position of hydrogen is non justified as it shows similarities with alkali metals like Na, K etc in having 1 electron in outermost shell and also it shows similarities with halogen in terms of electronegativity. So it position could not be justified.

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

Why is hydrogen in the left side?

Hydrogen is on the left side because like members of the IA group containing Lithium, Sodium and Potassium it has a normal charge of +1. Hydrogen is a non metal because it does not form metallic bonding. Hydrogen is not a conductor, is not malleable. Hydrogen is a gas, most metals are solids except for mercury.

What is the position of hydrogen in the periodic table?

Hydrogen is the first element of the periodic table as its atomic number is one, which means it has only one electron in its atom and thus only one electron is present in its outermost shell.

Where do you think should hydrogen be placed in the modern periodic?

The position of hydrogen in the periodic table is unclear because it resembles both the alkali metals and halogens in some of its properties. However, it is placed in the first group, above all the alkali metals in the modern periodic table because its electronic configuration is similar to that of alkali metals.

Is the position of hydrogen in the periodic table justified?

Alkali metal cations also exist as hydrates but the extent of hydration decreases as the size of alkali metal cation increases. It is not justified to include hydrogen either along with alkali metal of group 1 or halogens of group 17. The position of hydrogen in the periodic table is Anomalous.

Why is hydrogen not in a particular group?

Properties of hydrogen do not completely match any one of the above-mentioned groups. That is why position of hydrogen is still undecided. In the coming lines we will discuss why hydrogen can not be placed in a particular group in the periodic table. 1) Like alkali metals hydrogen has one electron in its valency shell.

Is the position of hydrogen still undecided?

Hydrogen resembles the elements of group I-A, IV-A and VII-A in some respects. Properties of hydrogen do not completely match any one of the above-mentioned groups. That is why position of hydrogen is still undecided.

How is hydrogen similar to other elements in the periodic table?

This is one of the factors that dictates the position of hydrogen in the table. Let us take a look at the similarities Electronic Configuration: Like all the elements of the group, Hydrogen also has one electron in its last shell, the valence shell. Let us take a look at the composition of valence shells of a few of these alkali metals.
