| chemical element elements and their compounds ; A substance made up of atoms with the same atomic number; common examples are hydrogen, gold, and iron | chemische elementen (en hun verbindingen) |
| chemical element | chemische elementen en hun verbindingen |
| chemical elements | elementen en hun verbindingen |
| element of group alkaline earth metals | elementen uit groep II aardalkalimetalen |
| element of group Any of the monovalent metals lithium, sodium, potassium, rubidium, caesium, and francium, belonging to group 1A of the periodic table. They are all very reactive and electropositive; alkaline | elementen uit groep I (alkalimetalen) |
| element of group Group IV consists of two subgroups: group IVb, main group, and group IVa. Group IVa consists of titanium, zirconium, and hafnium which are generally classified as transition metals. The main group consists of carbonium, silicium, germanium, tin, and lead. The main valency of the elements is IV, and the members of the group show a variation from nonmetallic to metallic behaviour in moving down the group. The reactivity of the elements increases down the group from carbon to lead. All react with oxygen on heating | elementen uit groep IV |
| element of group Group V consists of two subgroups: group Vb, the main group, and group Va. Group Va consists of vanadium, niobium, and tantalum, which are generally considered with the transition elements. The main group consists of nitrogen, phosphorus, arsenic, antimony, and bismuth | elementen uit groep V |
| element of group Group III consists of two subgroups: group IIIb and group IIIa. Group IIIa consists of scandium, yttrium, and lanthanium, which is generally considered with the lanthanoids, and actinium, which is classified with the actinoids. Group IIIb, the main group, comprises boron, aluminium, gallium, indium, and thallium | elementen uit groep III |
| element of group Any of the divalent electropositive metals beryllium, magnesium, calcium, strontium, barium, and radium, belonging to group 2A of the periodic table; alkaline earth metals | elementen uit groep II (aardalkalimetalen) |
| element of group Group VI consists of two subgroups: group VIb, the main group, and group VIa. Group VIa consists of chromium, molybdenum, and tungsten. The main group consists of oxygen, sulphur, selenium, tellurium, and polonium | elementen uit groep VI |
| element of group 0 | elementen uit groep 0 |
| element of group 0 A group of monatomic gaseous elements forming group 18 (formerly group 0) of the periodic table: helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn) | elementen uit groep 0 |
| element of group Any of the elements of the halogen family, consisting of fluorine, chlorine, bromine, iodine, and astatine | elementen uit groep VII |
| element of group alkaline | elementen uit groep I alkalimetalen |

| elements of group III | elementen uit groep III |
| elements of group IV | elementen uit groep IV |
| elements of group V | elementen uit groep V |
| elements of group VI | elementen uit groep VI |
| elements of group VII | elementen uit groep VII |
| fuel element | splijtstofelement |
| landscape elements | landschapselementen |

| nuclear fuel element A piece of nuclear fuel which has been formed and coated, and is ready to be placed in a reactor fuel assembly | splijtstofelement |
| nuclear fuel element | splijtstofelement |
| radical element | radicaal element |
| trace element Any of various chemical elements that occur in very small amounts in organisms and are essential for many physiological and biochemical processes | sporenelementen |
| trace element | sporenelementen |
| trace elements | sporenelementen |
| transition element One of a group of metallic elements in which the members have the filling of the outermost shell to 8 electrons interrupted to bring the penultimate shell from 8 to 18 or 32 electrons; includes elements 21 through 29 (scandium through copper), 39 through 47 (yttrium through silver), 57 through 79 (lanthanum through gold), and all known elements from 89 (actinium) on | overgangselementen |
