The notes available here are great for revision and studying on the go. e.g. Please explore the links below for the study notes and questions for each subject! Providing study notes, tips, and practice questions for students preparing for their O level or upper secondary examinations. 1 • Elements in Group IV can lose or gain electrons depending on reacting element. 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. Since less energy is needed, more energy resources can be conserved, e.g. I have also posted 2 exam-based questions on Features & Trends in the Periodic Table. transition metals and their compounds are used In the next few days, i am gog to… A periodic table is a listing of elements that are regulated in order of increasing atomic (proton) number. Eg. Rubidium will react violently with cold water. As atomic number increases down the group, the physical states change from gas (fluorine and chlorine) to liquid (bromine) and then to solid (iodine, astatine). Chlorine is oxidised to ClOH and reduced to HCl at the same time. Periodic Table of Elements. which elements in periodic table should an eighth grader preparing for GCE O Level know? are yellow and green. b. number of electrons in the outer shell. compounds formed often have characteristic colours. Atoms of elements in the same group have the same total number of electrons. Elements on left side periodic table lose ions to form, Elements on right side periodic table gain ions to form. It forms a covalent compound with hydrogen. So used for chromium-plating and in making stainless steel, titanium and its alloys are light but as strong as steel so used in aircraft construction, a strong metal that resists corrosion. This quiz is a demo quiz created to test O level Chemistry knowledge of the student by www.donason.com No comments: Post a Comment. 12 Sodium is in Group I of the Periodic Table. reacts vigorously with metals to form ionic salts, halogens become less reactive down the group. Let’s find out: Groups: It is a vertical column of elements. FREE (0) Popular paid resources.

I2 formed, have properties of both metals and non-metals, metalloids beneath the staircase line are called Poor Metals (eg tin and lead), poor conductors of heat and electricity (except graphite), many of these metals have variable oxidation state eg Copper(I) and Copper(II), Iron(II) and Iron(III). The equation for the reaction is: 2Na + 2H 2O 2NaOH + H 2 (a) State the name given to the elements in Group I.
