Why hydrogen is placed above alkali metals and not above non-metals in Modern Periodic Table?
It is much more common for hydrogen to lose an electron and become H+ than it is for it to become H- (like a halogen would), as in a hydride. Because it is possible for either behavior, though, some periodic tables DO show hydrogen in group 17. Some show it in group 1. Some show both, and some show hydrogen sitting in the middle by itself. It's a tricky one.
Why is the position of hydrogen not justified in the modern periodic table?
Hydrogen's position in the modern periodic table is often viewed as problematic because it shares characteristics with both alkali metals and halogens. While it has one electron in its outer shell, similar to alkali metals, it also readily forms compounds like halogens, indicating it can gain an electron. Additionally, hydrogen exists as a diatomic molecule (H₂) and can exhibit unique properties that do not align perfectly with any single group. This dual behavior complicates its classification, leading to ongoing debates about its appropriate placement.
Explain why hydrogen is not included in group 1 in most versions of the modern periodic table?
Hydrogen is not included in group 1 in most versions of the modern periodic table because it does not exhibit the typical characteristics of alkali metals found in group 1. While hydrogen can lose an electron to form a positive ion like alkali metals, it can also gain an electron to form a negative ion like halogens. This dual behavior makes hydrogen unique and not easily categorized with alkali metals. Therefore, it is often placed separately at the top of the periodic table.
What are the main groups in the modern periodic table of elements?
GroupsGroup 1 is the Alkali MetalsGroup 2 is the Alkaline Earth MetalsGroups 3 through 12 are the Transition Metals (includes the Lanthanide [elements 58-71] and Actinide Series [elements 90-103])Group 13 is the Boron GroupGroup 14 is the Carbon GroupGroup 15 is the Nitrogen GroupGroup 16 is the Oxygen GroupGroup 17 is the HalogensGroup 18 is the Noble Gases
The first element on the periodic table is what?
Dimitri Mendeleev is credited with the the creation of the first modern and rational periodic table of chemical elements; but other chemists also had contributions.
Why hydrogen is placed above alkali metals and not above non metals in modern periodic table?
The electron configuration of hydrogen is similar with that of alkali metals.
The elements in a group 1 of the periodic table are commonly called the?
The elements in Group 1 are also known as alkali metals, or they are sometimes referred to as the lithium family. Answer: Alkali Metals or Lithium Family

Where on periodic table can you find alkali metals?
Alkali metals can be found in Group 1 of the periodic table. These elements include lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr). They are highly reactive and are typically found in nature as compounds rather than in their pure form.
What group are are alkali metals?
Column 1 of a modern periodic table, except for hydrogen: lithium, sodium, potassium, rubidium, and cesium. (Probably francium is an alkali metal too, but it is so radioactive that not much chemistry has been done with it.)
Why position of hydrogen in modern periodic table is not certain?
because some of its properties resembles that of alkali metals i-e elements in group 1 and with the halogens i-e elements of group 17
Why hydrogen is not had proper place in periodic table?
Hydrogen posses properties of alkali metals while it also posses properties of halogens .That is why it cannot be placed in any of the either groups ,so it has been given a distinct place in modern periodic table. NOTE Hydrogen does not belong to group 1
What nonmetals are in the hydrogen family?
None. In modern periodic tables H is included in group 1- this is called the alkali metal family- all the other members of rhe group are metals. It is not usually called the hydrogen family. Hydrogen is included with the alkali metals in group 1 because its ouetr shell contains 1 electron- however hydrogen is different from the other members of the grouo in its chemistry.
Why is hydrogen not included in group 1 in modern periodic table?
Even though hydrogen has a vacant electron in its outer shell, like many of the elements in group 1 of the periodic table, it has unusual properties, e.g. it is a gas at room temperature, whereas the other elements are all solid. As a result, some forms of the periodic table show hydrogen above the rest in the table, in its own special place. However, it is still in group 1
What are group 1A elements exept for hydrogen that are on the left side of the modern periodic table?
The alkali metals are lithium (Li), sodium (Na), potassium (K), rubidium (Rb), caesium (Cs) and francium (Fr).

What period and group is francium in?
Francium is amrmber of the alkali metal familiy (group 1 in the Periodic Table of Mendeleev): Li, Na, K, Rb, Cs, Fr.
