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. :)
Where is alkali metals located on the periodic table and their group number?
The alkali metals are group 1, also known as group 1A.
Why is the element hydrogen not part of a group?
It is (1A).
What is the evidence that suggests that hydrogen should be in the first column of the periodic table?
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.
What are the elements in the group 1A on the periodic table?
There are 7 elements in group 1: hydrogen, lithium, sodium, potassium, rubidium, cesium, and francium. All of these (except hydrogen) are considered alkali metals. They react very easily with other elements.
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.
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?

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).
