The observations usually consist of some type of numerical measurement, although sometimes there is a more qualitative (non-numerical) description of the property. Transition Metals. Study the following graph and explain the trend in electronegativity of the group 2 elements. Harsh VJain. This interactive periodic table of element groups arranges the chemical elements according to periodicity or common properties. Periodic Table of Elements 2. Group 2: General Properties The elements in the group include beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra). For the metals (groups 1 to 13) the melting and boiling points increase as you go up the group. We also acknowledge previous National Science Foundation support under grant numbers 1246120, 1525057, and 1413739. They have the same number of electrons in their outer shell, so similar chemical properties. Chances are you will probably need a group 3 compound. Unless otherwise noted, LibreTexts content is licensed by CC BY-NC-SA 3.0. Alkaline metals are usually Shiny, silvery. Magnetism 8. These metals display a fair share of interesting properties which are absolutely fun to study about. Boron is unreactive towards oxygen in its crystalline form. Reactions with water . A great summary about Group 1 in the Periodic table - The Alkali Metals. Hardness 9. Yet they manage to be quite different from them. radium. The ionization energy for beryllium is 899.5, 737.7 for magnesium, 589.8 for calcium, 549.5 for strontium, 502.9 for barium and 509.3 for radium. As a result, the strength of the metallic bonds decreases going down the group. Alkali and alkaline earth metals are respectively the members of group 1 and group 2 elements. Group 1 metals are less reactive than group 2 metals. This means that the halogens all have similar chemical properties .

The alkaline-earth metals have very similar chemical and physical properties. Downloads. A few points to note about the groups are: Although hydrogen appears in group 1, it is not an alkali metal. PERIODIC TABLE GROUP 2 MENU . to personalise content to better meet the needs of our users. barium. Group 7 is on the right-hand side of the periodic table, next to group 0 The halogens show trends in their physical and chemical properties . Radium (Ra) These metal elements tend to stabilize their electron configuration by removing two outermost s electrons to obtain a noble ga… Top 10 blogs in 2020 for remote teaching and learning; Dec. 11, 2020 Electrical conductivity 6. 5 lessons • 49 m . Alkali Earth Metals – Group 2 Elements. Reactions with oxygen . Atomic number 10. Chemical properties of the halogens Atoms of group 7 elements all have seven electrons in their outer shell. Top 10 blogs in 2020 for remote teaching and learning; Dec. 11, 2020 Most of the chemistry has been observed only for the first three members of the group; chemical properties of both actinium and especially lawrencium are not well-characterized.
