The elements are the alkali metals.
because they have similar properties to the other elements in their groups
Main group elements have elements from groups 1 and 2, except hydrogen and groups 13 to 18. Main group elements are elements in groups who's lightest elements are shown by helium, lithium, boron, beryllium, carbon, nitrogen, oxygen, and fluorine.
There are 18 groups in the periodic table of elements.
There are 18 main groups in the modern periodic table of elements.
Elements located in groups 4 - 12 in the modern periodic table are considered as transition elements. Transition elements should not be confused with the d-block elements which are from groups 3 - 12.
The elements in the first two groups and in the last 6 groups. Basically all the elements except the inner transition and transition elements.
groups 11 and 12
There are 18 groups and 7 periods in the modern periodic table.
It is similar because you are putting rocks into groups like you are putting elements into groups
There are 18 groups on the periodic table. These groups are columns that contain elements with similar properties due to their shared electron configurations. The groups are numbered 1 to 18, with the first two groups referred to as the "s-block" elements and the last six groups classified as the "p-block" elements.
There are eight groups that make up the main group elements. They are groups 1, 2, and 13 - 18. They are also called the representative elements.
No, the elements in all groups do not ionise. Some of the elements share electrons to form compounds.
