The periodic table, also known as the periodic table of elements, arranges the chemical elements such as hydrogen, silicon, iron, and uranium according to their atomic number.The number of each element corresponds to the number of protons in its nucleus (which, in an uncharged atom, is the same as the number of electrons orbiting that nucleus). 18 Dec 2020. Section A will carry 50 marks and will consist of a variable number of compulsory structured questions. (RbCl, KCl, LiCl, CsCl), From left to right, elements gradually change from metal to non-metal. d. Metal consists of a lattice of cations in a sea of delocalised electrons. Elements are arranged on the Periodic Table in order of increasing atomic number, where each element has one proton more than the element preceding it; The table is arranged in vertical columns called Groups numbered 1 – 8 and in rows called Periods; Period: these are the horizontal rows that show the number of shells of electrons an atom has d. its metallic or non-metallic properties. Transition metals may form variable cation of 2+ or 3+. This table shows the pattern in the periodic table that Mendeleev developed and how the missing elements at … 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. Electrons orbit the atom's nucleus in energy levels. Oxygen is a chemical element with atomic number 8 which means there are 8 protons and 8 electrons in the atomic structure.

Elements in same group has the same number of valence shell electrons which the amount is the same as the group number. Main use is to galvanise iron to prevent it from rusting, unreactive metal and malleable. (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. Group II has elements with valency of 2 electrons. 2. When chlorine gas is bubbled through a colorless solution of potassium bromide, reddish brown color of bromine is seen. Thank you making it easy for reference. Your email address will not be published. What about it as a noble gas makes it so good at hiding?
