From example, we know elements in same group form same formula. 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.

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. Notes. 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). 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).

The GCSE Chemistry periodic table of elements is something which you have to get to know pretty well for your exam. The Royal Society of Chemistry's interactive periodic table features history, alchemy, podcasts, videos, and data trends across the periodic table. 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.
