Chapter 22: Problem 21

Give a reason why hydrogen might be placed along with the group 1 A elements of the periodic table.

Short Answer

Expert verified
Hydrogen might be placed along with the group 1A elements of the periodic table due to its similarity in valence electron configuration (1s1) and the ability to form a positive ion (H^+) by losing one electron, which is also a common property of group 1A elements. However, hydrogen is a unique element and may not fit perfectly in any group.

Step by step solution

01

Identify the properties of hydrogen

Hydrogen is the first element in the periodic table. It is a non-metal with one electron in its outermost shell. It can easily lose that electron to form a singly positive ion (H^+), which is a characteristic of metals. Adding to this, its electron configuration is 1s1.
02

Identify the properties of group 1A elements

Group 1A elements, also known as alkali metals, are located in the first column of the periodic table. They are characterized as metals with one electron in their outermost shell. These elements react vigorously with water and air, and they easily lose their single valence electron to form a singly positive ion (e.g. Na^+). The general electron configuration of alkali metals is ns1, where n represents the principal quantum number (n=2, 3, 4,...).
03

Compare hydrogen's properties with group 1A elements

Although hydrogen is a non-metal, it shares a similarity with group 1A elements by having one electron in its outermost shell. Additionally, both hydrogen and alkali metals can easily lose their single valence electron to form singly positive ions.
04

Conclusion

The reason why hydrogen might be placed along with the group 1A elements of the periodic table is due to the similarity in valence electron configuration and the ability to form a positive ion by losing one electron. However, it should be noted that hydrogen is a unique element that may not fit perfectly in any group and is often found alone at the top of the periodic table.
