| metals | Electropositive chemical elements characterised by ductility, malleability, luster, and conductance of heat and electricity. They can replace the hydrogen of an acid and form bases with hydroxyl radicals. (12 Dec 1998) |
| metals, actinoid | A series of radioactive elements from actinium, atomic number 89, to and including lawrencium, atomic number 103. They are the theoretical analogs of the rare earth metal series. (12 Dec 1998) |
| metals, alkali | Metals that constitute group ia in the periodic table. They are the most strongly electropositive of the metals. (12 Dec 1998) |
| metals, alkaline earth | Metals that constitute the group IIa in the periodic table. (12 Dec 1998) |
| metals, heavy | metals with high specific gravity, typically larger than 5. They have complex spectra, form coloured salts and double salts, have a low electrode potential, are mainly amphoteric, yield weak bases and weak acids, and are oxidizing or reducing agents (12 Dec 1998) |
| metals, light | Metals with low specific gravity, typically smaller than 5, characterised by a single valence (1, 2, or 3), a simple spectrum, strong electromotive force (positive), and colourless compounds. (12 Dec 1998) |
| metals, rare earth | Elements of group IIIb of the periodic table from lanthanum, atomic number 57, to and including lutetium, atomic number 71. (12 Dec 1998) |
| trace | 1. To mark out; to draw or delineate with marks; especially, to copy, as a drawing or engraving, by following the lines and marking them on a sheet superimposed, through which they appear; as, to trace a figure or an outline; a traced drawing. "Some faintly traced features or outline of the mother and the child, slowly lading into the twilight of the woods." (Hawthorne) 2. To follow by some mark that has been left by a person or thing which has preceded; to follow by footsteps, tracks, or tokens. "You may trace the deluge quite round the globe." (T. Burnet) "I feel thy power . . . To trace the ways Of highest agents." (Milton) 3. Hence, to follow the trace or track of. "How all the way the prince on footpace traced." (Spenser) 4. To copy; to imitate. "That servile path thou nobly dost decline, Of tracing word, and line by line." (Denham) 5. To walk over; to pass through; to traverse. "We do tracethis alley up and down." (Shak) Origin: OF. Tracier, F. Tracer, from (assumed) LL. Tractiare, fr.L. Tractus, p. P. Of trahere to draw. Cf. Abstract, Attract, Contract, Portratt, Tract, Trail, Train, Treat. 1. A mark left by anything passing; a track; a path; a course; a footprint; a vestige; as, the trace of a carriage or sled; the trace of a deer; a sinuous trace. 2. <chemistry> A very small quantity of an element or compound in a given substance, especially when so small that the amount is not quantitatively determined in an analysis;-hence, in stating an analysis, often contracted to tr. 3. A mark, impression, or visible appearance of anything left when the thing itself no longer exists; remains; token; vestige. "The shady empire shall retain no trace Of war or blood, but in the sylvan chase." (Pope) 4. <geometry> The intersection of a plane of projection, or an original plane, with a coordinate plane. 5. The ground plan of a work or works. Syn.-Vestige; mark; token. See Vestige. Origin: F. Trace. See Trace. Source: Websters Dictionary (01 Mar 1998) |
| trace conditioned reflex | A conditioned reflex established by applying the stimulus a short time before reinforcement; in the conditioned reflex of the animal so prepared, the response occurs at the same interval of time after the application of the stimulus as during the period of training. (05 Mar 2000) |
| trace conditioning | Conditioning when there is no temporal overlap between the conditioning stimulus and the unconditioned stimulus. (05 Mar 2000) |
| trace element | Any chemical element that an organism needs very small quantities of tosurvive. (09 Oct 1997) |
| trace elements | A group of chemical elements that are needed in minute quantities for the proper growth, development, and physiology of an organism. (12 Dec 1998) |
| trace nutrient | Essential dietary elements required only in small quantities. They are present in the body in amounts less than .005% of body weight. (12 Dec 1998) |
