Please explore the links below for the study notes and questions for each subject! • Keep an eye on the time. 12. d (Mg and Ca are in the same group in the Periodic Table), 15. d (Group I metals donate 1 outermost electrons to form X, 18. c (Chlorine, being more reactive than At, displaces At from its aqueous salt). When sodium is added to water, an alkaline solution is produced. (in simple terms, it refers to how much an element loves an electron), Electronegativity is the tendency for an atom to attract electrons to itself, Electropositivity is the tendency for an atom to lose an electron, - Have the same atomic number (number of protons) but different mass number or different number of neutrons, low densities and melting points - these increases down the group, reacts easily in air so they're kept in oil, loses one outermost electron to form an ion of +1 charge eg. Newer Post Home. ... Chemistry and uses of acids, bases & salts, the periodic table, metals, atmosphere and environment and Organic Chemistry. oil to generate electricity in producing iron. Which element reacts most vigorously with cold water? Elements close to dividing line in periodic table in back part of the note (in bold) are called metalloids having properties of metals and non-metals. Li, react violently with air or oxygen, catching fire, and burning with characteristic flame colors to form white oxides. Check your answers if you have time at the end. In the oxidation process, oxidation number of chlorine increased from 0 in Cl, In the reduction process, oxidation number of chlorine decreased from 0 in Cl. Elements are arranged in order of proton numbers, Across the period, the elements change from metals to non-metals, Elements close to the staircase line, like silicon or germanium, can have some properties of the metals and of the non-metals -->, : indicates number of electrons in the outermost shell of an atom, : indicates the number of electron shells in an atom, Ionization energy is the minimum amount of energy required to completely remove an electron from a gaseous atom, of a molecule or atom is the energy change when an electron is added to the neutral atom to form a negative ion. The colour intensity also increases from pale yellow (fluorine) to yellowish green (chlorine) and then to red-brown (bromine) and finally to black (iodine and astatine). • Try to answer every question. Since less energy is needed, more energy resources can be conserved, e.g. When chlorine gas is bubbled through a colorless solution of potassium bromide, reddish brown color of bromine is seen. Periodic Table secondary school. Sodium in Group I forms NaCl, so other elements in Group I does the same.

Since transition elements speed up chemical processes in industries, they saves time in manufacture, Less energy is needed for manufacture in industries, hence lower cost. Proton number increase going down the group, On each sides of periodic table, the change of the proton number small & gradual, In transition metals, the gradual change is larger, Given chlorine, iodine and bromine of Group VII forms molecules of Cl. Periodic Table: Relative charges and approximate relative masses of protons, neutrons and electrons. GROUP 0 THE NOBLE GASES helium, … . To avoid this, the metals are stored under oil, They also react vigorously with water, forming the alkaline hydroxide and releasing hydrogen gas, Because alkali metals are such reactive metals, they combine directly with reactive non-metals such as the halogens to form salts, low melting and boiling points - increases down the group, elements become darker and solidify down the group, because of their atomic size, which increases down the group, therefore it becomes more difficult for the nucleus to attract an electron to form an ion, most reactive is fluorine; least reactive is iodine, all halogens form ions with single negative charge eg F, Any halogen above another in the group will displace it from a solution of its salt ---->, least reactive elements in the gaseous state; do not form bonds, have stable electronic configuration with full electrons on their shells. No comments: Post a Comment. It is a good conductor of electricity. Square Tips and notes for English, General Paper, and … d. Group I elements are very good conductors of electricity.
