Group 2 metals: Alkaline earth metals (Periodic Table #2)

The alkaline earth elements are metallic elements found in the second group of the periodic table. All alkaline earth elements have an oxidation number of +2, making them very reactive. Because of their reactivity, the alkaline metals are not found free in nature. In the modern IUPAC nomenclature, the alkaline earth metals comprise the group 2 elements.They are all shiny, silvery-white. This group lies in the s-block of the periodic table as all alkaline earth metals have their outermost electron in an s-orbital.

The Alkaline Earth Metals are:
• Beryllium
• Magnesium
• Calcium
• Strontium
• Barium
• Radium

Barium

Magnesium

Beryllium

Calcium

Radium


Strontium

 Further experiments: Experiments have been conducted to attempt the synthesis of element 120 which is likely to be the next member of the group, but they have all met with failure. However, element 120 may not be an alkaline earth metal due to relativistic effects which are predicted to have a large influence on the chemical properties of superheavy metals.

Group 14-16: Non metals ( Periodic Table #6)

Non-metals are the elements in groups 14-16 of the periodic table. Non-metals are not able to conduct electricity or heat very well . Non-metallic elements are very brittle , and not malleable (i.e.cannot be rolled into wires or pounded into sheets). The non-metals exist in two of the three states of matter at room temperature: gases (such as oxygen) and solids (such as carbon). The non-metals have no metallic luster, and do not reflect light . They have oxidation numbers of ±4, -3, and -2. The Non-Metal elements are: Hydrogen Carbon Nitrogen Oxygen Phosphorus Sulfur Selenium  Although five times more elements are metals than nonmetals, two of the nonmetals —hydrogen and helium—make up over 99 per cent of the observable Universe,  and one—oxygen—makes up close to half of the Earth's crust, oceans and atmosphere.   Living organisms are also composed almost entirely of nonmetals,  and nonmetals form many more compounds than metals CREDIT: wikiped...

Structure of atoms #2 : Electronic Configuration

Image
The arrangement of electrons in the various shells/orbits/energy levels of an atom of the element is known as electronic configuration. Bohr-Bury scheme Electrons revolve around the nucleus in different energy levels or shells and each shell is associated with definite energy. The energy of the K shell is the least while those of L, M, N and O shells increases progressively. We also know that any system that has least energy is the most stable. 1 s t  energy level is K shell 2 n d  energy level is L shell 3 r d  energy level is M shell 4 t h  energy level is N shell and so on. Electronic configuration of an element Bohr and Bury Scheme - Important Rules 1. Maximum number of electrons that can be accommodated in a shell is given by 2n 2  where n=shell number For 1 s t  energy level, n = 1 Maximum number of electrons in 1 s t  energy level = 2n 2 2 x (1) 2 = 2 For 2 n d  energy level n=2 Maximum number of...
