How Halogens And Alkali Metals Are Extremely Reactive Whereas Noble Gases Are Not Reactive

Metals and Halogens reactions Elements such as fluorine, chlorine, bromine, iodine, and astatine belong to Group 7, Halogens. At room temperature, fluorine is a yellow gas, chlorine is a pale green gas, bromine is a red liquid, and iodine is a purple solid. Astatine is a radioactive element, therefore it exists only in small amounts. All the halogens exist in diatomic molecules. They have high ionization energies and are the most electronegative elements. Their electron configuration ns2 np5 make...

Atoms Molecules And Elements Paper

that element. First we can learn about how halogens and alkali metals are extremely reactive, where as noble gases are non reactive. Secondly we have to compare the properties of molecules formed from atoms in similar families versus . Lastly, we can learn about what is meant by the electronic structure of atoms and how knowing the electronic structure of the atoms aid in the prediction of chemical reactions. Halogens and Alkali Metals compared to Noble gases “In the 1870’s, the Russian chemist...

Alkali Metals

Alkali Metals Introduction Alkali metals refer to six elements belonging to the Group IA of the long form of the Modern Periodic Table, viz. Lithium (Li), Sodium (Na), Potassium (K), Rubidium (Rb), Cesium (Cs) and Francium (Fr). Fr is a radioactive element. These elements are called so because they form strongly alkaline oxides and hydroxides. Electronic Configuration of Alkali Metals Each of the alkali metals has one electron in their outermost (valence) shell, which is just outside an inert...

Chemical Properties of Metals, Non-Metal

Chemical Prperties of Metals Most metals are chemically reactive, reacting with oxygen in the air to form oxides over changing timescales (for example iron rusts over years and potassium burns in seconds). The alkali metals react quickest followed by the alkaline earth metals, found in the leftmost two groups of the periodic table. Examples: 4Na + O2 → 2Na2O (sodium oxide) 2Ca + O2 → 2CaO (calcium oxide) 4Al + 3O2 → 2Al2O3 (aluminium oxide) The transition metals take much longer to...

History of the Periodic Table

of the Periodic Table 1. Explain how scientific observations led to the development of, and changes to, the periodic table. Dmitri Mendeleev- first periodic table, organized 63 known elements according to properties, organized into rows and columns. He wrote names, mass and chemical properties on each. Julius lothar Meyer- independently worked in German , similar to Mendeleev Henry Gwyn Jeffrey’s Moseley: worked with Ernest Rutherford experimented with 38 metals, he found that the positive charge...

Low-Impact Fiber-Reactive Dyes

Low-Impact Fiber-Reactive Dyes The sustainability of our environment is crucial in saving the livelihood of the people and the planet. Since we are all interdependent, we will all have to do our part in sustaining our environment for the future. We should always be questioning and doing more about it rather than just talking or ignoring the facts. Most of us do not realize the excessive use of resources we have taken advantage of over the years. Generations past have exploited our planet which...

except the transition metals. The group number show the number of electrons on the outer most shell. Group 0 does not apply to this rule because they are the noble gases, they however have the outermost electron shell full. Oxygen (O) will have 6 electrons in its outer shell. How is the Periodic Table Split? Non-metals: These are the elements on right side of line, as well as hydrogen, which is, which is in-group 1 because it only has 1 electron on its outer shell. Non-metals cannot conduct electricity...

Chemistry Alkali Metals

The alkali metals are found in group 1 of the Periodic table. They are very reactive metals and do not occur freely in nature. Alkali metals are malleable, ductile, and are good conductors of heat and electricity. Alkali metals can also explode if they are exposed to water. The Alkali metals are: lithium, sodium, potassium, rubidium, cesium, and francium. Lithium The mineral petalite, which contains lithium, was discovered by a Brazilian scientist named Jose Bonifacio towards the end of the...
