Because Hydrogen is in the same group (I) as the alkali metals (Li, Na, K, etc.) without being a metal!
Hydrogen and periodic table
Hydrogen (H) is separated as it has only 1 electron and so exhibits some unique behavior.
Most elements lose or gain electrons to reach a noble gas configuration. Most they only do one or the other (but not both usually). For instance fluorine (F) will always gain 1 electron to have the electronic configuration of neon (Ne), while lithium (Li) will always lose one electron to have the configuration of helium (He).
Hydrogen is unique in that it can both gain one electron to have the configuration of He, or it can lose one electron and just be a lone proton with no electrons. A half-filled shell (in this case the 1s orbital) is very unstable. It is better to have no electrons or two electrons. Hydrogen can behave either like an alkali metal and be H+ (having lost 1 electron) or can act more like a halogen and be H- (having gained 1 electron).
What else can I help you with?
What group and row is hydrogen in on the periodic table?
Hydrogen is found in group 1 row 1 of the periodic table
What element belongs to the hydrogen family?
The element that belongs to the hydrogen family is hydrogen itself. Hydrogen is located in group 1 of the periodic table, known as the alkali metals.
What element is located in first row of group 1?
It is hydrogen. This element is the only one in its group because it is extremely unique and shares none of the properties of other gases.
What group is sodium hydroxide in the periodic table?
Sodium hydroxide is a compound. Only elements are found in the periodic table, not compounds.
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
In what period is hydrogen located at the periodic table?
Hydrogen is located in Group 1A of the Periodic Table.
What is the group that hydrogen is in?
Hydrogen is a non-metal; it's in group VII
Why is hydrogen (H) placed with elements in Group 1A?
Properties of Hydrogen. Hydrogen is a nonmetal and is placed above group in the Periodic Table because it has ns1 electron configuration like the alkali metals.
Were are nonmetals located in the periodic table?
the nonmetals are located in the right of the periodic table and only one (hydrogen) is located in group 1, period 1
Is hydrogen its own group on the periodic table?
No, hydrogen is not its own group on the periodic table. It is located in Group 1, but it is not a typical alkali metal like the elements in that group. Hydrogen is unique because it has properties of both metals and nonmetals, and its placement in the periodic table is a subject of debate among chemists.
Which element would you expect to be located in group 1 of the periodic table?
Hydrogen, lithium, sodium, potassium, rubidium, cesium and francium are the elements located in group 1 of the periodic table.
What group and row is hydrogen in on the periodic table?
Hydrogen is found in group 1 row 1 of the periodic table
What does hydrochloric acid mean in the periodic table?
Hydrochloric acid comprises of elements-hydrogen and chlorine. Hydrogen is placed above in group-1 and chlorine in group-17
In what group are non metals located in the periodic table?
Non-metals are located in several groups on the periodic table: Group 14 (Carbon group), Group 15 (Nitrogen group), Group 16 (Chalcogens), and Group 17 (Halogens). These elements are located to the right of the periodic table and have properties such as poor conductivity and often participate in chemical reactions by gaining electrons.
What is the correct placement of hydrogen in the periodic table?
It is placed in group 1, period 1 on the modern periodic table
What s block element is not located in group 1A or group 2A in the periodic table?
One example of a block element that is not located in group 1A or group 2A in the periodic table is carbon, which is a p-block element. Carbon is located in group 4A (14) of the periodic table and is known for its diverse bonding properties, forming a wide range of compounds.
What group is hydrogen in in the periodic table?
Hydrogen is the first element in the periodic table of Mendeleev - atomic number 1. Hydrogen is placed in the group and period 1 of this table.
