What type of elements are in group 1A?
Alkalene metals like hydrogen are present
Is it true the group 1A elements except for hydrogen are known as the alkali metals?
Yes
Why is hydrogen placed at the top of the periodic table and not in group 1?
Hydrogen is in fact in group 1 physically although not considered an alkali metal. It is at the top because the table is arranged by increasing atomic number; hydrogen is atomic number one, so it's first on the table.
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 s block element is not located in group 1A or group 2A in the periodic table?
hydrogen
Why hydrogen placed with the elements in group 1A?
because it has s1 configuration.
What elements are found in Group 1A sometimes referred to as Group 1?
Potassium and Hydrogen
Why is it that hydrogen is placed in the metal group?
Hydrogen is placed in the metal group because it only needs to lose one electron to be stable just like lithium, sodium, potassium etc It also has the same number of valence electrons as the rest of the elements in group 1a. :)
Why is hydrogen placed with the element in group 1a?
valence electrons and electronic configuration.
Why is hydrogen grouped with elements in group 1a?
valence electrons and electronic configuration.
What type of elements are in group 1A?
Alkalene metals like hydrogen are present
Is it true the group 1A elements except for hydrogen are known as the alkali metals?
Yes
Where do you find an alkali?
Alkali is a group of elements, not just one specific elements. Alkali metals are Group 1A elements starting with Hydrogen then lithium and so on.
Where is alkali metals located on the periodic table and their group number?
The alkali metals are group 1, also known as group 1A.
In what period is hydrogen located at the periodic table?
Hydrogen is located in Group 1A of the Periodic Table.
What is then main difference between period and group?
Groups are the (vertical) columns on the periodic table of the elements, while (horizontal) periods are the rows on the table. Hydrogen is the only one that doesn't really belong in a group although it is usually placed in either group 1A or group 7A.
Why is the element hydrogen not part of a group?
It is (1A).
