the three main groups are that you gey(:
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 eight groups that make up the main group elements. They are groups 1, 2, and 13 - 18. They are also called the representative elements.
The three main elements of a triangle are its three sides, three angles, and three vertices.
The three main groups in science are chemistry,biology and physics.
The main group elements are groups 1, 2, and 13 - 18.
Groups 1, 2, and 13 - 18 are the main group elements, also called the representative elements.
There are 18 main groups in the modern periodic table of elements.
The representative, or main group elements are the elements in groups 1, 2, and 13 - 18.
