An extended periodic table theorises about chemical elements beyond those currently known in the periodic table and proven up through oganesson , which completes the seventh period row in the periodic table at atomic number Z As of [update] , no element with a higher atomic number than oganesson has been successfully synthesized; all elements in the eighth period and beyond thus remain purely hypothetical.

It is measured by Pauling scale. Flourine is assigned the value of 4 Trends across the Periods and Groups a The electro-negativity increases from left to right in a period as the number of protons in the nucleus increases and attraction forces are increased b The electro-negativity decreases from top to bottom in a group as the distance from nucleus is increased We know that Non-metallic elements have strong tendency to gain electrons. Therefore, electronegativity is directly related to that non-metallic properties of elements.

The elements in the periodic table are arranged in order of increasing atomic number. All of these elements display several other trends and we can use the periodic law and table formation to predict their chemical, physical, and atomic properties. Understanding these trends is done by analyzing the elements electron configuration; all elements prefer an octet formation and will gain or lose electrons to form that stable configuration. We can never determine the atomic radius of an atom because there is never a zero probability of finding an electron, and thus never a distinct boundary to the atom.

Periodic table and atomic structure 1. Explanations for trends in values: i down a group ii across a period covalent radii of main group elements only. First ionisation energies.

Explanations for general trends in values: i down a group ii across a period main group elements and for exceptions to the general trends across a period. Symbols of elements 1 - 36 The periodic table as a list of elements arranged so as to demonstrate trends in their physical and chemical properties. Brief statement of the principal resemblances of elements within each main group, in particular alkali metals, alkaline earth metals, halogens and noble gases.

Chemical bonding 2. Students should be able to describe the reactions of the first three alkali metals with oxygen, chlorine and water. In Group 1, the reactivity of the elements increases going down the group. Students should be able to: explain how properties of the elements in Group 1 depend on the outer shell of electrons of the atoms.

Predict properties from given trends down the group. The halogens are non-metals and consist of molecules made of pairs of atoms. Students should be able to describe the nature of the compounds formed when chlorine, bromine and iodine react with metals and non-metals. In Group 7, the further down the group an element is the higher its relative molecular mass, melting point and boiling point.

A more reactive halogen can displace a less reactive halogen from an aqueous solution of its salt. Students should be able to: explain how properties of the elements in Group 7 depend on the outer shell of electrons of the atoms. They are unreactive and do not easily form molecules because their atoms have stable arrangements of electrons. The noble gases have eight electrons in their outer shell, except for helium, which has only two electrons.

The boiling points of the noble gases increase with increasing relative atomic mass going down the group. Students should be able to: explain how properties of the elements in Group 0 depend on the outer shell of electrons of the atoms. AQA Combined science: Synergy 4. Explain how the observed simple properties of Group 7 depend on the outer shell of electrons of the atoms and predict properties from given trends down the group.

Extended periodic table

If you went into a grocery store, how would you find a loaf of bread or a gallon of milk? Where would you find the ice cream? What about your favorite cereal, an apple, or an orange? Grocery stores are organized in a manner that helps customers easily find items. Similar items are grouped together.

As early chemists worked to purify ores and discovered more elements, they realized that various elements could be grouped together by their similar chemical behaviors. One such grouping includes lithium Li , sodium Na , and potassium K : These elements all are shiny, conduct heat and electricity well, and have similar chemical properties. A second grouping includes calcium Ca , strontium Sr , and barium Ba , which also are shiny, good conductors of heat and electricity, and have chemical properties in common. However, the specific properties of these two groupings are notably different from each other. For example: Li, Na, and K are much more reactive than are Ca, Sr, and Ba; Li, Na, and K form compounds with oxygen in a ratio of two of their atoms to one oxygen atom, whereas Ca, Sr, and Ba form compounds with one of their atoms to one oxygen atom.

These trends can be predicted merely by examing the periodic table and can be explained and understood by analyzing the electron configurations of the elements. Elements tend to gain or lose valence electrons to achieve stable octet formation. In addition to this activity, there are two other important trends. First, electrons are added one at a time moving from left to right across a period. As this happens, the electrons of the outermost shell experience increasingly strong nuclear attraction, so the electrons become closer to the nucleus and more tightly bound to it.

Finally, we shall examine some of the periodic trends in the physical and chemical properties of the elements. WHY DO WE NEED TO CLASSIFY ELEMENTS?
