the main groups are numbered from 1 to 7 going from left to right, and the last group on the right is Group 0. the block in between Group 2 and Group 3 is where the transition metals...
Mar 22, 2022 · All elements in Group 2 (also called alkali earth metals) have two electrons in their outermost shell in the s sub-shell (s 2 electron configuration) Redox reactions are the most common reaction of the Group 2 elements.
In chemistry, a group (also known as a family) [1] is a column of elements in the periodic table of the chemical elements. There are 18 numbered groups in the periodic table; the 14 f-block columns, between groups 2 and 3, are not numbered.

Elements within the same group share the same number of valence electrons. The number of valence electrons depends on the octet rule. For example, elements in group 1 have 1 valence electron, elements in groups 3-12 have a variable number of valence electrons, and elements in group 17 have 7 valence electrons. The lanthanides and actinides, located...
Sometimes chemists classify element groups according to shared properties, which do not strictly adhere to individual columns. These groups go by the names alkali metals, alkaline earth metals, transition metals, basic metals, nonmetals, halogens, noble gases, lanthanides, and actinides. Under this system, hydrogen is a nonmetal. The nonmetals, hal...
Elements within a period share the same number of electron shells and the same highest unexcited electron energy level. Elements within a period display periodic table trends, moving from left to right, involving atomic and ionic radius, electronegativity, There are seven element periods. Some periods contain more elements than others because the n...

In order to move from Group 2A to Group 3A, an individual had to move (or transition) through columns 3 through 12.

Dec 6, 2019 · Group 2 elements are: Beryllium. Magnesium. Calcium. Strontium. Barium. Radium. Group 2 elements are called alkaline metals because they form alkaline solutions, hydroxides, when reacting with water and their oxides are found in the earth’s crust. ALKALINE METALS. They have low electron affinity.
