How do you justify the position of hydrogen at the top of various groups?
Hydrogen is a unique element of the Periodic Table. Due to its similarities in properties it can be placed at the top of group 1A or 4A or 7A.
Why hydrogen placed with the elements in group 1A?
Hydrogen is placed with the elements in group 1A (1) because it has one electron in its outermost shell, similar to other group 1A elements like lithium, sodium, and potassium. However, hydrogen is unique as it is not a metal like the other elements in this group, exhibiting properties of both metals and nonmetals.
Which element has one valence electrons?
Any element in group 1
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.
In what period is hydrogen located at the periodic table?
Hydrogen is located in Group 1A of the 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 is the group that hydrogen is in?
Hydrogen is a non-metal; it's in group VII
Which is the lightest element in group 1A?
Hydrogen, which is properly a member of the periodic column. If the properties of hydrogen are considered too little like those of the other elements in the this column, the alkali metals, so that only the latter are considered members of column IA, then the answer would be lithium.
Why H cannot be placed in group 1a although its electronic configuraion is similar to group 1a?
It is so because it also resembles the the halogens. The enthalpy of bond dissociation of Hydrogen is quite similar to Halogens. Its properties resemble both alkali metals and the halogens but differ from them too. So, it is not placed with any of them.
What element from Group 1A is most reactive?
francium
Why is hydrogen separate from the rest of 1A?
Hydrogen is separate from the rest of Group 1A elements because it displays unique properties that do not fit the typical characteristics of alkali metals (Group 1A elements). For example, hydrogen can form both positive and negative ions, while other Group 1A elements typically form only positive ions. Additionally, hydrogen can exhibit nonmetallic properties in addition to metal-like behavior, setting it apart from the rest of Group 1A.
What is the evidence that suggests that hydrogen should be in the first column of the periodic table?
Hydrogen should be in the first column of the periodic table because it has one electron in its outer shell, like the other elements in Group 1 (alkali metals). It also displays similar chemical properties to the alkali metals, such as the tendency to lose an electron to form a positive ion. Additionally, hydrogen behaves like a nonmetal in many instances, which supports its placement at the beginning of the periodic table.
