ATOMS - answer✔✔- FUNDAMENTAL SUBMICROSCOPIC UNIT OF ALL MASS. SIZE
OF
THE ATOM AND ITS WEIGHT HAVE INTERESTED SCIENTISTS FOR A LONG PERIOD.
SUBSEQUENTLY, EXPERIMENTS WERE DEVISED TO DETERMINE THE SIZE AND
WEIGHT OF THE VARIOUS ATOMS. THE LIGHTEST OF ALL ATOMS IS HYDROGEN.
PROTON - answer✔✔- A SUBATOMIC PARTICLE HAVING A POSITVIE CHARGE
IDENTICAL
IN MAGNITUDE TO THE NEGATIVE CHARGE OF AN ELECTRON AND, TOGETHER
WITH THE
NEUTRON, A COMPONENT OF ALL ATOMIC NUCLEI. THE PROTON FORMS, BY
ITSLEF, THE
NUCLEUS OF THE HYDROGEN ATOM. THE MASS OF A PROTON IS APPROXIMATELY
1836 TIMES
THAT OF AN ELECTRON AND THE MASS OF AN ATOM IS CONTAINED ALMOST
ENTIRELY IN THE
,NUCLEUS. THE PROTON HAS AN INTRINSIC ANGULAR MOMENTUM OR SPIN AND
THUS A
MAGNETIC MOMENT (VERY SMALL MAGNETIC FIELD). THE NUMBER OF PROTONS
IN THE NUCLEUS OF AN ATOM DETERMINES WHAT ELEMENT IT IS; THE ATOMIC
NUMBER OF AN ELEMENT DENOTES THE NUMBER OF PROTONS IN THE NUCLEUS.
ELECTRON - answer✔✔- A SUBATOMIC MPARTICLE THAT, ALONG WITH PROTONS
AND
NEUTRONS, MAKE UP THE ATOMS THE FLOW OF AN ELECTRIC CURRENT IN A
CONDUCTOR IS
CAUSED BY THE DRIFTING OF FREE ELECTRONS IN THE CONDUCTOR. HEAT
CONDUCTION IS
ALSO PRIMARILY A PHENOMENON OF ELECTRON ACTIVITY. THE CHARGE OF THE
ELECTRON IS
THE BASIC UNIT OF ELECTRICITY. ELECTRONS HAVE HALF-INTEGRAL SPIN; SPIN IS A
PROPERTY OF SUBATOMIC PARTICLES THAT INDICATES THE PARTICLE'S ANGULAR
MOMENTUM.
NEUTRON - answer✔✔- A SUBATOMIC PARTICLE THAT IS NEUTRAL THEREFORE
HAS NO
CHARGE. IT IS LOCATED IN THE NUCLEUS AND SERVES AS A STABILIZER. THE MASS
OF A
NEUTRON IS SLIGHTLY GREATER THAN THE PROTON MASS AND HAS AN
ENORMOUS EFFECT
ON THE QUANTUM SPIN VALUE OF AN ELEMENT. THE NET CHARGE ON A
NEUTRON IS 0
MAGNETISM - answer✔✔- IS DESCRIED AS THE ABILITY OF A SUBSTANCE TO
ATTRACT IRON, COBALT AND NICKEL. IT IS THE POWER OR FORCE CREATED BY A
,SUBSTANCE HAVING THE PROPERTY OF CREATING OR INDUCING MAGNETIC
DIPOLES. THE MAGNETIC FIELD OF
ANY MAGNET HAS A DIRECTION, SIGNIFIED NORTH AND SOUTH. THIS PROPERTY
OF A MAGNET MAKES IT A DIPOLE. DIPOLE - A MAGNETIC FIELD CHARACTERIZED
BY ITS OWN MAGNETIC NORTH AND SOUTH POLES SEPARATED BY A FINITE
DISTANCE.
MAGNETIC SUSCEPTIBILITY - answer✔✔- DEFINED AS THE TENDENCY OF A
SUBSTANCE TO ATTRACT OR REPEL MAGNETIC LINES OF FORCE DEPENDENT ON
THE MAGNETIC PROPERTIES OF ITS ELECTRONS.
DIAMAGNETIC - answer✔✔- THE PROPERTY OF MOST SUBSTANCES WITH PAIRED
ORBITAL ELECTRONS THAT HAVE OPPOSITE SPINNING AND THEIR MAGNETIC
MOENTS CANCEL
EACH OTHER OUT. SUBSTANCES WITH DIAMAGNETIC SUSCEPTIBILITY WEAKLY
ATTRACT OR REPEL MAGNETIC LINES OF FORCE. MAGNETIC SUSCEPTIBILITY OF
MOST HUMAN BODY TISSUES ARE DESCRIBED AS DIAMAGNETIC.
PARAMAGNETIC - answer✔✔- THE PROPERTY OF SUBSTANCES WITH POSITIVE
MAGNETIC SUSCEPTIBILITY THAT ATTRACT AND REPEL MAGNETIC LINES OF
FORCE. THESE
SUBSTANCES (GADOLINIUM, METHEMOGLOBIN, FREE RADICALS) CONTAIN ONE
OR MORE
UNPAIRED ORBITAL ELECTRONS AND PRODUCE MARKED REDUCTIONS IN THE T1
AND T2
RELAXATION TIMES. UNPAIRED ORBITAL ELECTRONS SPIN IN THE SAME
DIRECTION AND HAVE THE TENDENCY TO LINE UP WITH THE MAGNETIC FIELD.
THEREFORE PRODUCING ADDITIONAL MAGNETIC FIELDS.
, SUPER-PARAMAGNETIC - answer✔✔- THE PROPERTY OF SUBSTANCES WITH
LARGE
POSITIVE MAGNETIC SUSCEPTIBILITY WHICH STRONGLY ATTRACT OR REPEL
MAGNETIC LINE
SOF FORCE. THESE SUBSTANCES (HEMOSIDERIN AND SUPERPARAMAGNETIC IRON
OXIDE SPIO) HAVE A SINGLE MAGNETIC DOMAIN AND ARE MAGNETIZED IN A
MAGNETIC FIELD. THEIR
MAGNETIC SUSCEPTIBILITIES ARE MUCH LARGER THAN THOSE OF
PARAMAGNETIC
SUBSTANCES AND SIMILAR TO THOSE OF FERROMAGNETIC MATERIALS. UNLIKE
FERROMAGNETIC SUBSTANCES, SUPERPARAMAGNETIC MATERIALS DO NOT
EXHIBIT RESIDUAL MAGNETISM WHEN THE EXTERNAL FIELD IS REMOVED.
FERROMAGNETIC - answer✔✔- THE PROPERTY OF SUBSTANCES WITH LARGE
POSITIVE MAGNETIC SUSCEPTIBILITY THAT BECOME MAGNETIZED WITHIN A
MAGNETIC FIELD AND REMAIN MAGNETIZED AGTER BEING REMOVED FROM THE
MAGNETIC FIELD. FERROMAGNETIC SUBSTANCES INCLUDE A NUMBER OF IRON
AN COBALT-CONTAINING METALS.
MAGNETIC FIELD - answer✔✔- A VECTOR QUANTITIY CONSISTING OF BOTH A
NORTH
AND SOUTH POLE; IT EXERTS AN INDUCTION FORCE ON FERROMAGNETIC AND
PARAMAGNETIC SUBSTANCES. WHEN SYMBOLIZING THE FLOW AND AREA OF A
MAGNETIC FIELD, SPECIAL LINES ARE USED; THEY ARE FIELD OR FLUX LINES
FIELD OR FLUX LINES - answer✔✔- MEASURE THE FLOW AND AREA OF A
MAGNETIC
FIELD. THE STRONGEST AREA OF THE MAGNETIC FIELD IS WHERE THE FIELD OR
FLUX LINES CONVERGE AND IS CALLED THE ISOCENTER. AWAY FROM THE
ISOCENTER THE FIELD OR FLIX LINES REPRESENT THE FRINGE FIELDS.
